Question

The principal of an elementary school wanted to see if there are differences in the abilities of first, second, and third graders to render a three-dimensional image into a two- dimensional drawing (as judged by trained coders). All students were attending the same school, and data were collected during the same semester.

What test I use?

-Independent samples t test

-ANOVA

-Paired samples t test

-Correlation

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
