Question description

Based on each of the three research scenarios provided, open the High School Longitudinal Study dataset using SPSS software, then choose and run the appropriate t test (use either the Independent sample t test, Paired sample t test, or the One sample t test).

Once you perform your t test analyses, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.

Write a 2- to 3-paragraph analysis of your t test results for each research scenario (Scenarios are attached) and include the SPSS syntax and output. 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.

Week 6 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. © 2016 Laureate Education, Inc.

Scenario 1

In the first scenario, one sample t-test was used. This was used due to the fact that we needed to
understand if there existed a significant difference between the mean of the data used and 6.The
following was the procedure for the analysis:
1: On the main menu, click Analyze > Compare Means > One-Sample T Test
2. Click the variable Q46a. Make sure you move it to the Test Variable box by use of the
arrow button. In the box, enter the mean of the population you are comparing by changing the
current value of "0" to "6".
3. Click the options button. The One-Sample T-Test will be presented. Ensure that the default is
set at 95% confidence intervals. You will consider excluding cases analysis by analysis in the
value missing area. The default should be 95% confidence intervals and Exclude cases analysis
by analysis in the –Missing Values– area.
4. Click the Continue button, which well lead you to One-Sample T Test dialogue box
5. Press OK button for the output to be produced.
