Science is not just knowledge. It is also a method for obtaining knowledge.
5 steps of scientific method What is the sixth step of the scientific method? Place the steps of the scientific method in the correct order. quizlet 7 steps of the scientific method Scientific understanding is organized into theories.
The scientific method is a step-by-step process used by researchers and scientists to determine if there is a relationship between two or more variables. Psychologists use this method to conduct psychological research, gather data, process information, and describe behaviors.
It involves careful observation, asking questions, formulating hypotheses, experimental testing, and refining hypotheses based on experimental findings.
How it is Used
The scientific method can be applied broadly in science across many different fields, such as chemistry, physics, geology, and psychology.
In a typical application of this process, a researcher will develop a hypothesis, test this hypothesis, and then modify the hypothesis based on the outcomes of the experiment.
The process is then repeated with the modified hypothesis until the results align with the observed phenomena. Detailed steps of the scientific method are described below.
Keep in mind that the scientific method does not have to follow this fixed sequence of steps; rather, these steps represent a set of general principles or guidelines.
7 Steps of the Scientific Method
Psychology uses an empirical approach
Empiricism (founded by John Locke) states that the only source of knowledge comes through our senses – e.g., sight, hearing, touch, etc.
Empirical evidence does not rely on argument or belief.
Thus, empiricism is the view that all knowledge is based on or may come from direct observation and experience.
The empiricist approach of gaining knowledge through experience quickly became the scientific approach and greatly influenced the development of physics and chemistry in the 17th and 18th centuries.
Step 1: Make an Observation (Theory Construction)
Every researcher starts at the very beginning.
Before diving in and exploring something, one must first determine what they will study it seems simple enough!
By making observations, researchers can establish an area of interest. Once this topic of study has been chosen, a researcher should review existing literature to gain insight into what has already been tested and determine what questions remain unanswered.
This assessment will provide helpful information about what has already been comprehended about the specific topic and what questions remain, and if one can go and answer them.
Specifically, a literature review might implicate examining a substantial amount of documented material from academic journals to books dating back decades.
The most appropriate information gathered by the researcher will be shown in the introduction section or abstract of the published study results.
The background material and knowledge will help the researcher with the first significant step in conducting a psychology study, which is formulating a research question.
This is the inductive phase of the scientific process.
Scientific method steps quizlet Briefly explain each. A theory is a well-developed set of ideas that propose an explanation for observed phenomena. What Are the Elements of a Good Hypothesis? It states that the results are not due to chance and that they are significant in terms of supporting the theory being investigated.Observations yield information that is used to formulate theories as explanations. A theory is a well-developed set of ideas that propose an explanation for observed phenomena.
Inductive reasoning moves from specific premises to a general conclusion. It starts with observations of phenomena in the natural world and derives a general law.
Step 2: Ask a Question
Once a researcher has made observations and conducted background research, the next step is to ask a scientific question.
A scientific question must be defined, testable, and measurable.
A useful approach to develop a scientific question is: “What is the effect of…?” or “How does X affect Y?”
To answer an experimental question, a researcher must identify two variables: the independent and dependent variables.
The independent variable is the variable manipulated (the cause), and the dependent variable is the variable being measured (the effect).
An example of a research question could be, “Is handwriting or typing more effective for retaining information?” Answering the research question and proposing a relationship between the two variables is discussed in the next step.
Step 3: Form a Hypothesis (Make Predictions)
A hypothesis is an educated guess about the relationship between two or more variables.
A hypothesis is an attempt to answer your research question based on prior observation and background research. Theories tend to be too complex to be tested all at once; instead, researchers create hypotheses to test specific aspects of a theory.
For example, a researcher might ask about the connection between sleep and educational performance.
Do students who get less sleep perform worse on tests at school?
It is crucial to think about different questions one might have about a particular topic to formulate a reasonable hypothesis. It would help if one also considered how one could investigate the causalities.
It is important that the hypothesis is both testable against reality and falsifiable.
This means that it can be tested through an experiment and can be proven wrong.
The falsification principle, proposed by Karl Popper, is a way of demarcating science from non-science.
Scientific method steps quizlet biology Scientific Method Steps The scientific method is used by every scientist around the world. The fifth of the Scientific Method is Collect and Analyze Results in which you modify the procedure if needed. This process allows scientists to analyze and understand various psychological phenomena, but it also provides investigators and others a way to disseminate and debate the results of their studies. A detailed record of psychological studies and all scientific studies is vital to clearly explain the steps and procedures used throughout the study.It suggests that for a theory to be considered scientific, it must be able to be tested and conceivably proven false.
To test a hypothesis, we first assume that there is no difference between the populations from which the samples were taken. This is known as the null hypothesis and predicts that the independent variable will not influence the dependent variable.
Examples of ifthen Hypotheses:
- If one gets less than 6 hours of sleep, then one will do worse on tests than if one obtains more rest.
- If one drinks lots of water before going to bed, one will have to use the bathroom often at night.
- If one practices exercising and lighting weights, then ones body will begin to build muscle.
The research hypothesis is often called the alternative hypothesis and predicts what change(s) will occur in the dependent variable when the independent variable is manipulated.
It states that the results are not due to chance and that they are significant in terms of supporting the theory being investigated.
Although one could state and write a scientific hypothesis in many ways, hypotheses are usually built like ifthen statements.
Step 4: Run an Experiment (Gather Data)
The next step in the scientific method is to test your hypothesis and collect data.
A researcher will design an experiment to test the hypothesis and gather data that will either support or refute the hypothesis.
The exact research methods used to examine a hypothesis depend on what is being studied. A psychologist might utilize two primary forms of research, experimental research, and descriptive research.
The scientific method is objective in that researchers do not let preconceived ideas or biases influence the collection of data and is systematic in that experiments are conducted in a logical way.
Experimental Research
Experimental research is used to investigate cause-and-effect associations between two or more variables.
This type of research systematically controls an independent variable and measures its effect on a specified dependent variable.
Experimental research involves manipulating an independent variable and measuring the effect(s) on the dependent variable. Repeating the experiment multiple times is important to confirm that your results are accurate and consistent.
One of the significant advantages of this method is that it permits researchers to determine if changes in one variable cause shifts in each other.
While experiments in psychology typically have many moving parts (and can be relatively complex), an easy investigation is rather fundamental.
Still, it does allow researchers to specify cause-and-effect associations between variables.
Most simple experiments use a control group, which involves those who do not receive the treatment, and an experimental group, which involves those who do receive the treatment.
An example of experimental research would be when a pharmaceutical company wants to test a new drug.
They give one group a placebo (control group) and the other the actual pill (experimental group).
Descriptive Research
Descriptive research is generally used when it is challenging or even impossible to control the variables in question. Examples of descriptive analysis include naturalistic observation, case studies, and correlation studies.
One example of descriptive research includes phone surveys that marketers often use.
While they typically do not allow researchers to identify cause and effect, correlational studies are quite common in psychology research. They make it possible to spot associations between distinct variables and measure the solidity of those relationships.
Step 5: Analyze the Data and Draw Conclusions
Once a researcher has designed and done the investigation and collected sufficient data, it is time to inspect this gathered information and judge what has been found.
Researchers can summarize the data, interpret the results, and draw conclusions based on this evidence using analyses and statistics.
Upon completion of the experiment, you can collect your measurements and analyze the data using statistics. Based on the outcomes, you will either reject or confirm your hypothesis.
Analyze the Data
So, how does a researcher determine what the results of their study mean?
Statistical analysis can either support or refute a researchers hypothesis and can also be used to determine if the conclusions are statistically significant.
When outcomes are said to be statistically significant, it is improbable that these results are due to luck or chance. Based on these observations, investigators must then determine what the results mean.
An experiment will support a hypothesis in some circumstances, but sometimes it fails to be truthful in other cases.
What occurs if the developments of a psychology investigation do not endorse the researchers hypothesis?
Scientific method steps quizlet chemistry Experimental research involves manipulating an independent variable and measuring the effect s on the dependent variable. Once a researcher has made observations and conducted background research, the next step is to ask a scientific question. Based on the outcomes, you will either reject or confirm your hypothesis. Understand audiences through statistics or combinations of data from different sources.It does mean that the study was worthless. Simply because the findings fail to defend the researchers hypothesis does not mean that the examination is not helpful or instructive.
This kind of research plays a vital role in supporting scientists in developing unexplored questions and hypotheses to investigate in the future.
After decisions have been made, the next step is to communicate the results with the rest of the scientific community.
This is an integral part of the process because it contributes to the general knowledge base and can assist other scientists in finding new research routes to explore.
If the hypothesis is not supported, a researcher should acknowledge the experiments results, formulate a new hypothesis, and develop a new experiment.
We must avoid any reference to results proving a theory as this implies % certainty, and there is always a chance that evidence may exist that could refute a theory.
Draw Conclusions and Interpret the Data
When the empirical observations disagree with the hypothesis, a number of possibilities must be considered.
It might be that the theory is incorrect, in which case it needs altering, so it fully explains the data.
Alternatively, it might be that the hypothesis was poorly derived from the original theory, in which case the scientists were expecting the wrong thing to happen.
It might also be that the research was poorly conducted, or used an inappropriate method, or there were factors in play that the researchers did not consider.
This will begin the process of the scientific method again.
If the hypothesis is supported, the researcher can find more evidence to support their hypothesis or look for counter-evidence to strengthen their hypothesis further.
In either scenario, the researcher should share their results with the greater scientific community.
Step 6: Share Your Results
One of the final stages of the research cycle involves the publication of the research.
Scientific method psychology: Test Hypothesis and Collect Data: Fill two identical containers with the same amount of room temperature water. Make recommendations for further study. Add to Folders Close. Experimental research is used to investigate cause-and-effect associations between two or more variables.
Once the report is written, the researcher(s) may submit the work for publication in an appropriate journal.
Usually, this is done by writing up a study description and publishing the article in a professional or academic journal. The studies and conclusions of psychological work can be seen in peer-reviewed journals such as Developmental Psychology, Psychological Bulletin, the Journal of Social Psychology, and numerous others.
Scientists should report their findings by writing up a description of their study and any subsequent findings.
This enables other researchers to build upon the present research or replicate the results.
As outlined by the American Psychological Association (APA), there is a typical structure of a journal article that follows a specified format. In these articles, researchers:
- Supply a brief narrative and background on previous research
- Give their hypothesis
- Specify who participated in the study and how they were chosen
- Provide operational definitions for each variable
- Explain the measures and methods used to collect data
- Describe how the data collected was interpreted
- Discuss what the outcomes mean
A detailed record of psychological studies and all scientific studies is vital to clearly explain the steps and procedures used throughout the study.
So that other researchers can try this experiment too and replicate the results.
The editorial process utilized by academic and professional journals guarantees that each submitted article undergoes a thorough peer review to help assure that the study is scientifically sound. Once published, the investigation becomes another piece of the current puzzle of our knowledge base on that subject.
This last step is important because all results, whether they supported or did not support the hypothesis, can contribute to the scientific community.
Publication of empirical observations leads to more ideas that are tested against the real world, and so on.

Once published, the investigation becomes another piece of the current puzzle of our knowledge base on that subject.
By replicating studies, psychologists can reduce errors, validate theories, and gain a stronger understanding of a particular topic.
Step 7: Repeat the Scientific Method (Iteration)
Now, if ones hypothesis turns out to be accurate, find more evidence or find counter-evidence.
If ones hypothesis is false, create a new hypothesis or try again.
One may wish to revise their first hypothesis to make a more niche experiment to design or a different specific question to test.
The amazingness of the scientific method is that it is a comprehensive and straightforward process that scientists, and everyone, can utilize over and over again.
So, draw conclusions and repeat because the scientific method is never-ending, and no result is ever considered perfect.
The scientific method is a process of:
- Making an observation.
- Forming a hypothesis.
- Making a prediction.
- Experimenting to test the hypothesis.
The procedure of repeating the scientific method is crucial to science and all fields of human knowledge.
