Question

A social worker in South Phoenix delivered an intervention on financial literacy. The program is six weeks long (one hour per week). She collected pre and post- test surveys in order to determine if participants’ knowledge on financial literacy increased due their involvement in the program.

Review the table below and answer the following questions.

Table 1. Financial literacy intervention change from pre to post test

	M	SD	t	p
Financial Literacy Knowledge			5.04	.001
Pre test	7.25	1.78
Post test	8.42	1.20

1. Was a dependent or independent t-test used to analyze the data? How do you know?

2. Is the difference between pre test and post test statistically significant (use the traditional rejection level)?

3. Did measures of financial literacy knowledge improve or decline? How do you know?

Answer 1

1:

Independent variable: Involvement in program "financial literacy"

Dependent variable: Pre test Survey scores and post test survey scores

2:

Since p-value is less than 0.05 so at 5% level of significance we can conclude that the difference between pre test and post test is statistically significant.

3:

Since post test sample mean is greater than pre test sample mean and test statistics is positive and we reject the null hypothesis so we can conclude that measures of financial literacy knowledge improve.
