What is a hypothesis? By Saul McLeodupdated August 10, A hypothesis plural hypotheses is a precise, testable statement of what the researchers predict will be the outcome of the study. This usually involves proposing a possible relationship between two variables: In research, there is a convention that the hypothesis is written in two forms, the null hypothesis, and the alternative hypothesis called the experimental hypothesis when the method of investigation is an experiment.
Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion Communicate Your Results Following the scientific methodwe come up with a question that we want to answer, we do some initial research, and then before we set out to answer the question by performing an experiment and observing what happens, we first clearly identify what we "think" will happen.
We make an "educated guess. We set out to prove or disprove the hypothesis. What you "think" will happen, of course, should be based on your preliminary research and your understanding of the science and scientific principles involved in your proposed experiment or study.
In other words, you don't simply "guess. You're not pulling your statement out of thin air. Instead, you make an "educated guess" based on what you already know and what you have already learned from your research.
If you keep in mind the format of a well-constructed hypothesis, you should find that writing your hypothesis is not difficult to do.
You'll also find that in order to write a solid hypothesis, you need to understand what your variables are for your project. If I never water my plant, it will dry out and die. That seems like an obvious statement, right?
The above hypothesis is too simplistic for most middle- to upper-grade science projects, however. As you work on deciding what question you will explore, you should be looking for something for which the answer is not already obvious or already known to you.
When you write your hypothesis, it should be based on your "educated guess" not on known data. Similarly, the hypothesis should be written before you begin your experimental procedures—not after the fact. Hypotheses Tips Our staff scientists offer the following tips for thinking about and writing good hypotheses.
The question comes first. Before you make a hypothesis, you have to clearly identify the question you are interested in studying. A hypothesis is a statement, not a question. Your hypothesis is not the scientific question in your project. The hypothesis is an educated, testable prediction about what will happen.
A good hypothesis is written in clear and simple language. Reading your hypothesis should tell a teacher or judge exactly what you thought was going to happen when you started your project. Keep the variables in mind. A good hypothesis defines the variables in easy-to-measure terms, like who the participants are, what changes during the testing, and what the effect of the changes will be.
For more information about identifying variables, see: Variables in Your Science Fair Project. Make sure your hypothesis is "testable. You should also be able to repeat your experiment over and over again, if necessary. To create a "testable" hypothesis make sure you have done all of these things: Thought about what experiments you will need to carry out to do the test.
Identified the variables in the project. Included the independent and dependent variables in the hypothesis statement. This helps ensure that your statement is specific enough.
You may find many studies similar to yours have already been conducted. What you learn from available research and data can help you shape your project and hypothesis.
Dec 21, · How to Write Predictions and Hypotheses in Psychological Research Reports This post discusses the topic of predictions in psychological research. The main aim of the post is to provide assistance to researchers who are in the process of writing . Nov 05, · In psychology, the hypothesis might focus on how a certain aspect of the environment might influence a particular behavior. Unless you are creating a study that is exploratory in nature, your hypothesis should always explain what you expect to happen during the . One of the ways that you can tell if you have written an "answerable" experimental question is to try and reduce the question down into variables (see "variables" module).In psychology experiments reported in scholarly journals the form of these questions and/or hypotheses varies.
Don't bite off more than you can chew! Answering some scientific questions can involve more than one experiment, each with its own hypothesis. Make sure your hypothesis is a specific statement relating to a single experiment. Putting it in Action To help demonstrate the above principles and techniques for developing and writing solid, specific, and testable hypotheses, Sandra and Kristin, two of our staff scientists, offer the following good and bad examples.
Good Hypothesis Poor Hypothesis When there is less oxygen in the water, rainbow trout suffer more lice. By its very nature, it is not testable. There are no observations that a scientist can make to tell whether or not the hypothesis is correct. This statement is speculation, not a hypothesis.Newton's hypothesis demonstrates the techniques for writing a good hypothesis: It is testable.
It is simple. It is universal. It allows for predictions that will occur in new circumstances. It builds upon previously accumulated knowledge (e.g., Newton's work explained the observed orbits of the planets).
Hypothesis Writing: examples EXPERIMENT OR CORRELATION? EXPERIMENT CORRELATION Operationalise IV (sauna or igloo) Operationalise DV (time to do a piece jigsaw) Think of a difference between two groups. The research hypothesis will be directional (one-tailed) if theory or existing evidence argues a particular ‘direction’ of the predicted results, as demonstrated in the two hypothesis examples above.
This is a testable hypothesis - he has established variables, and by measuring the amount of oxygen in the water, eliminating other controlled variables, such as temperature, he can see if there is a correlation against the number of lice on the fish. This is an example of how a gradual focusing of research helps to define how to write a hypothesis.
