Analysis of t test results – Essaylink

Write a 2 to 3-paragraph analysis of your t test results for each research scenario and include the SPSS syntax and output. If you are using the Afrobarometer Dataset,

report the mean of Q1 (Age). If you are using the HS Long Survey Dataset, report the mean of X1SES. Do not forget to evaluate if the t test assumptions are met,

justify the selection of type of t test, and report the effect size. Based on your results, provide an explanation of what the implications of social change might be.

Scenarios 1. As an international development researcher, you would like to know African Citizen’s perceptions about current levels of democracy. Your working

hypothesis is that a series of reforms have increased African views of the level of democracy today. You do not have a good research design to compare attitudes before

and after the reforms, but know that leaders and development experts would like to see a value of 6, on the scale of 1–10. Using the data from the 2015 Afrobarometer,

determine whether perceptions about current levels of democracy statistically differ from a value of 6. Please provide: a 1–2 APA style paragraph statement that

furnishes an answer to this question, note the relevant statistics, comment on meaningfulness and include your relevant SPSS output.

2. As an international development researcher, you have already tested whether perceptions about the current levels of democracy differ from a value of 6. Given recent

social change movements in North Africa, you now want to determine whether there is a statistical difference in these perceptions between North Africa and Southern

Africa. Using the data from the 2015 Afrobarometer, please provide: a 1–2 APA style paragraph statement that furnishes an answer to this question, note the relevant

statistics, comment on meaningfulness, and include your relevant SPSS output.

3. As an educational researcher, would like to know whether high school student’s perceptions about mathematical utility changed between their freshman and senior

year. Each respondent is asked the same series of questions about the utility of mathematics in their future during their freshman and senior year. These questions are

combined to form one variable of mathematical utility; higher values indicate higher levels of mathematical utility. Using the High School Longitudinal Survey, please

provide: a 1–2 APA style paragraph statement that furnishes an answer to this question, note the relevant statistics, comment on meaningfulness, and include your

relevant SPSS output.
