Textbook Problem

Research has demonstrated strong gender differences in teenagers’ approaches to dealing with mental health issues (Chandra & Minkovitz. 2006). In a typical study, eighth-grade students are asked to report their willingness to use mental health services in the event they were experiencing emotional or other mental health problems. Typical data for a sample of n = 150 students are shown in the following table.

**a.**Do the data show a significant relationship between gender and willingness to seek mental health assistance? Test with α = .05.**b.**Compute Cramér’s V to measure the size of the treatment effect.

**a.**

To determine

**To check:** Whether there is significant relationship between gender and willingness to seek mental health assistance for the given question.

Explanation

**Given info:**

A sample of 150 students was involved in a study based on “the willingness to use mental health services and gender”. Use

**Calculations:**

Step 1: Null Hypothesis and Alternate Hypothesis are:

Step 2: For the given sample, degrees of freedom equals:

With

Step 3:

The formula to calculate expected frequency is:

Substitute

For the category “males”, the expected frequencies are:

Similarly, for the category “females”, the expected frequencies are:

**b.**

To determine

**To Find:** The value of Cramer’s V for the given question.
