Question

1. Now think about how you can summarize your expectations for each independent variable (IV) into one sentence. The first part of the sentence should describe the relationship you expect. The second part of the sentence should describe what you expect this relationship to show. Often in psychology, we are looking for group differences. (Later in the semester, we will see situations where we are looking for associations or correlations among variables.) A typical hypothesis statement might then look something like this:

I propose that 4 year-olds and 7 year-olds will perform differently on a standardized reading test, where 7 year-olds will score higher on the test than 4 year-olds.

Write your hypothesis statements (one per IV) in the space below:

Answer 1

Null hypothesis (Ho): The mean score of the 4-year olds and the mean score of the 7-year olds are the same

Alternative hypothesis (Ha): The 7-years olds have a significantly high mean score than the 4-year olds.
