Question

Randomly selected groups of 120 parents and 150 teachers from one school district are surveyed about their attitudes toward inclusion. One of the questions asks them whether they oppose or support inclusions and their responses to this question are recorded in the following table. The data were analyzed using a chi square test. The obtained chi square value is 5.65, significant at the .02 level (p=.02).

GROUP	SUPPORT	OPPOSE
Parent	75	45
Teachers	72	78

a. Which chi square test should be used to analyze the data and answer the research questions? Explain.

b.             Is there a statistically significant difference in the responses of the parents and teachers? Explain.

Answer 1

Solution:-

a) The chi square test should be used to analyze the data is Chi square test for Homogeneity.

Null hypothesis: The null hypothesis states that the proportion of responses of the parents and teachers are same.

Alternative hypothesis: At least one of the null hypothesis statements is false.

b) Yes, there a statistically significant difference in the responses of the parents and teachers.

Since the p-value(0.02) is less than 0.05, hence we have to reject the null hypothesis.
