Hypotheses - The low down


Let’s talk about hypotheses!

A hypothesis is simply a prediction that is made by a psychologist which states what you believe will happen. The hypothesis is a precise statement that can be tested to show the relationship between the two variables (whether the independent variable is affecting the dependent variable thus making the experiment significant).

An experimental hypothesis can either be directional or non directional.

1.       A directional hypothesis predicts the type of difference we want to see in the results. (shows the direction of the difference in results)
For example – The results will show that men are better at driving around obstacles than women

2.       A non directional hypothesis predicts that there will be a difference in the results but does not specify where the difference will be.
For example – The results will show a difference in the driving abilities of men and women around obstacles.

3.       A Null hypothesis is a prediction that states there will be no differences in the results (as in some cases the results of a study will not prove any differences between condition’s results)
For example – There will be no difference in the results between men and women in their ability to be able to go round obstacles. Any differences found will be due to chance.

This should help you when making your hypotheses for your practicals.
