Statistics in Psychology SPSS Assignment #2 Carlton Spring 2021 Directions: This assignment is designed for you to practice: 1) choosing the appropriate statistical technique to answer different research questions, and 2) running different statistical analyses in SPSS. This is an INDIVIDUAL assignment. Although you can consult with your teammates, everyone should hand in their own individual assignment, which should be qualitatively different from your peers! There are three research problems below, using variables from the HSData.sav dataset, which can be found on Canvas. This data file contains 200 observations from a sample of high school students with demographic information about the students (gender, socio-economic status, ethnic background) as well as their scores on standardized tests of reading, writing, mathematics, and social studies. Please complete the full NHST process for any TWO of the problems below, including all of the following information: a. The appropriate test for evaluating the research question. b. What variable you used as an IV, and which as the DV. c. The measurement type (Nominal, Ordinal, or Scale) of each variable. If the variable is Nominal, please list the categories and what number indicates membership in these categories. d. Means, standard deviations, and graphs of the dependent variable (using the EXPLORE command in SPSS). e. Null/Alternative hypotheses. f. Alpha level, degrees of freedom (if appropriate), one/two tailed test type (if appropriate), other information as appropriate. g. Appropriate test statistic/table, as a copied and pasted/screenshot/table of SPSS result, including post hoc tests if appropriate. h. A full write up for step four, including: a. A decision about the null hypothesis b. A written explanation about the results of the test, including means and standard deviations, and a final answer to your research question c. Proper APA style string, including effect size and confidence intervals, if appropriate. Each problem you complete is worth 25 points. You can complete the third research problem for an additional 10 points of extra credit. If you choose to complete all three, please indicate what problem you would like counted for extra credit – otherwise, I will automatically treat the third problem as extra credit. Problems: 1) You would like to see if there is a significant difference in writing scores based on the student’s socio-economic status. Test this hypothesis using the variables “write” and “ses”. 2) You would like to see whether students’ test grades in science change between freshman and senior year. Test whether or not there is a significant difference in science scores between these two time points using the variables “sciencefresh” and ‘sciencesen”. 3) You would like to know if student’s science scores as freshman predict how well they perform in math during their senior year. Use the variables “math” and “sciencefresh”.
