You, the researcher, write a hypothesis and null hypothesis.This lesson explores the process and terminology used in writing a hypothesis and null hypothesis.If you can't measure it, then you can't form a hypothesis about it because you can't confirm or reject it.
If test scores don't change, then our hypothesis was incorrect and we will reject it.
You probably also noticed that we changed 'studying' to 'test scores' and the vague term about 'bright light' into 'amount of light.' This is an example of operationalizing, which is finding a way to measure or quantify a variable.
First off, it is an if-then statement: 'If we increase..., then the participant's...' This creates a prediction that we can test by increasing the light on participants as they study and then see if their test scores go down.
It also means that the hypothesis can be proven correct or incorrect based on what happens to the test scores.
For example: While there are many ways to state a hypothesis, you may wish to revise your first hypothesis in order to make it easier to design an experiment to test it.
For example, let's say you have a bad breakout the morning after eating a lot of greasy food.This is the bottom, or base, which you will build up from. I am curious about the effects of bright lights on studying.You take the thing you are interested in and turn it into a question.You may wonder if there is a correlation between eating greasy food and getting pimples.You propose a hypothesis: Next, you need to design an experiment to test this hypothesis.Research typically includes a hypothesis, and when this is the case you will form a null hypothesis as a counterbalance to ensure there is a way to disprove your prediction.A null hypothesis is the prediction a researcher hopes to prove false.A hypothesis is an educated prediction that provides an explanation for an observed event.An observed event is a measurable result or condition.Here is mine: 'What is the effect of bright light on studying?' That's how easy it is to write a research question.
