Suppose you are interested in studying whether temperature affects spatial reasoning abilities. You decide to test spatial reasoning using completion time scores for the paper-folding test with five people, repeating the test on each person with three different temperatures (40 degrees, 60 degrees, and 80 degrees Fahrenheit).


In this experiment, the null hypothesis is that:


a. There are no differences in the mean completion times among the temperatures compared

b. There are no individual differences in the completion time means

c. The completion time mean for at least one temperature is different from another


The factor of interest is the ____________, and the dependent variable is the ___________

The null hypothesis in this situation is "There are no differences in the mean completion times among the temperatures compared".

What is a null hypothesis?

This is a hypothesis that states the independent variable or factor being studied has not effect on the dependent variable.

This implies the temperature has no effect on the completion times of the paper-folding test.

What is the factor of interest?

It is the effect of temperature because this is the factor being manipulated on purpose.

What is the dependent variable?

This refers to the factor being studied, in this case, these are the spatial reasoning abilities, which are tested through a specific test.
