review the test scenarios found in this week's Learning Resources and consider the three different approaches of tests:

Independent sample ttest

Paired sample test

One sample test

Follow step by step through for how to use SPSS software, then choose and run the appropriate test.

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.

Based on each of the three research scenarios provided, open the . the Afrobarometer dataset from this week's Learning Resources using SPSS software, then choose and run the appropriate test.

.

For this Assignment:

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.

Use proper APA format, citations, and referencing for your analysis, research questions, and output.
