You want to compare differences in prior arrests across ethnicity. In your study, you measured ethnicity as White = 0, Black = 1, Hispanic = 2, and Other = 3. Prior arrests was recorded as the number of prior arrests. Which test would you perform to see if arrests differ across different ethnic categories?

Group of answer choices

T-tests are appropriate when you have a continuous dependent variable and two-category nominal independent variable.

Group of answer choices

True

False

When interpreting the findings of a t-test, if the observed t-value is greater than the critical t-value, which of the following would we conclude?

Group of answer choices

There is no significant mean difference.

None of the answers are correct.

Fail to reject the null hypothesis.

There is a significant mean difference.

When conducting an ANOVA, a significant F-test tells us between which specific groups/categories there are significant differences.

Group of answer choices

True

False

Which of the following is an assumption of the t-test?

Group of answer choices

All of these are assumptions of the t-test

The variable you are comparing two groups on is continuous (i.e., interval or ratio).

The sampling difference of the differences between mean scores is normally distributed

The observations from each group are independent of each other (e.g., they are not the same individuals measured at two different times)
