A related-samples t test, also known as a paired-samples t test, is appropriate when the same participants are observed in each level of the independent variable. This type of test compares the means of two related groups to determine if there is a statistically significant difference between them. Since this study only has two levels of the independent variable, a related-samples t test is the most appropriate choice.
