Week 10-Mini-Task

Before attempting this mini-task you should study Chapter 13 of the prescribed textbook (Marketing Research).

Using the data about Internet Usage (link to the data below), you need to conduct the following tests (use default 95% confidence level in your analysis):

1. One Sample T-test: test whether Familiarity changed from previous year value of 4.45. How your answer changes whether you use one-tailed vs two-tailed test?

2. Independent Samples T-test: pick any variable and compare it for males and females. Which variables can and cannot be used in this test? Why?

3. Paired samples T-test: compare whether attitudes are on the same level or not. Explain what are the requirements for these two variables to be eligible for this test?

4. ANOVA: conduct any ANOVA test (hint: you can use 2 groups for your analysis). Explain which variables can be used for this analysis.

For all test you have to:

Justify why this test can be used with selected variables.

State null and alternative hypotheses (mathematically and in words).

Interpret the results.

In your answer you should include screenshots from SPSS outputs. Submissions without screenshots will not be accepted.
