Question

A physics instructor believes natural light improves learning and randomly assigns a total of 50 students to a natural light condition (n=25) or an artificial light condition (n=25). Both groups receive a learning task and are given a test scored as number correct. What condition below will you assess for the appropriate statistical test for this study?

Do the groups have similar standard deviations?

Are the scores normally distributed in each condition?

Does the relationship appear linear?

Are expected cell sizes greater than 5?

Explanation / Answer

A physics instructor believes natural light improves learning for this he randomly assigns a total of 50 students to a natural light condition (n=25) or an artificial light condition (n=25) Both groups receive a learning task and are given a test scored as number correct.

Here we have to check performance of both groups from a provided learning task the appropriate condition below wi for the statistical test for this study is,Does the relationship appear linear? because if both groups appear linear relationship then it is easy to determine that relationship is positive or negative by using correlation coefficient. if the correlation coefficient is nearly equal to 1 means there is strong positive relation ship between groups indictes no impact of natural light and artificial light on study. if the correlation coefficient is nearly equal to -1 means there is strong negative relation ship between groups indictes impact of natural light and artificial light on study.
