Question

question 1
which of the following options is suitable for a two - dependent - sample test?
compare the math test scores of two independent groups of students from two different schools
compare the pre - training and post - training scores of employees in a leadership program
compare the job satisfaction levels of employees in two unrelated organizations
compare the average income levels of individuals based on their education level

Explanation:

A two - dependent - sample test is used when the samples are related. In the case of comparing pre - training and post - training scores of employees in a leadership program, the same group of employees is measured twice (before and after training), so the samples are dependent.

• For comparing math test scores of two independent groups of students from two different schools, the groups are independent.
• For comparing job satisfaction levels of employees in two unrelated organizations, the groups are independent.
• For comparing the average income levels of individuals based on their education level, the samples (individuals with different education levels) are independent.

Answer:

Compare the pre - training and post - training scores of employees in a leadership program.
