Research topic: Screen time hours affect academic ability

Using the SPSS make a crosstab of your variables and a measures of association table.

1. Post a brief explanation of your topic. Include your research question and a broad research hypothesis -- that is, the relationship of IV to DV. (For example, educational attainment affects family income in US adults.)
2. Run a crosstab on your variables. Be sure to explain your findings, including a description of the table, a calculation of the epsilons, and a discussion of the 10% rule.
3. Run the correct measure of association for your variables (Choose one - either Pearson R, Gamma, Phi, Cramer's V or Lambda). Explain what the output means in terms of strength and direction of the relationship. Interpret Proportional Reduction of Error (PRE) using the following statement: Knowing the IV will reduce error in predicting the DV by *%.

Copy the crosstab and measure of association table into the discussion window or into a document (PDF, MS Word) and attach to discussion. If your table does not fit to the page, choose "copy special" and then "images" or take a screen shot of the table to copy/past into the window.
