Create a study for which you will need to conduct an independent-samples t test. 12 points (1 point for each of the questions below) NOTE: One variable will need to be on a nominal scale of measurement. The other will need to be on an interval or ratio scale. Research Question: Independent Variable: How measured and units: Dependent Variable: How measured and units: Research Hypothesis: Brief Description of Study Design: Be sure to include your n! Null Hypothesis: Alternative Hypothesis: Alpha Level: Probability of making a Type I Error: One or Two-tailed Test? SCROLL RIGHT Database: 4 points (correct structure 2; correct data 2) Data Analysis: 18 points (2 points for each question below) NOTE: Use at least n = 25 NOTE: I must be able to see the formulas for any computations you do in the pink cells immediately adjacent to them. ID "Column Title" "Column Title" Group labels (e.g., 1 = ?; 2 = ?) Mean of Group 1: Mean of Group 2: Value of t statistic: degrees of freedom: p-value of statistic: Reject null hypothesis? Effect size Interpretation of study results: Briefly discuss the quality of your study. How confident are you that your accurate and WHY?

Do you think these results might represent a Type I o error? You can discuss things such as sample size, the quality of the meas representativeness of sample, and the study design. omputations you do in the pink cells or in ow confident are you that your results are ults might represent a Type I or Type II le size, the quality of the measures used, y design.
