Assignment: Testing for Bivariate Categorical Analysis
For this Assignment, you will consider three different scenarios. Each of these scenarios include a research question. You will examine each scenario, choose a categorical data analysis and run a sample test. For this Assignment: Using the SPSS software, open the Afrobarometer dataset. Afrobarometer. (2016). Merged data. Retrieved from, http://afrobarometer.org/data/merged-round-6-data-36-countries-2016 Based on the dataset you chose and for each research scenario provided, using the SPSS software, choose a categorical data analysis and run a sample test. For this Assignment: Write a 1- to 2-paragraph analysis of your categorical data results for each research scenario. In your analysis, display the data for the 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 question, and display of output. Scenario #1 Results of your literature review conclude that trust in the police is an integral part of any democracy. You wish to test whether a relationship between trust in the police and presence of democracy (measured with dichotomous variable) exists in Africa. Using Afrobarometer 2015, 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. Scenario #2 Following up on your previous analysis, you now wish to determine whether a relationship exists between citizen trust in police and whether respondents reside in rural, urban or semi-urban settings? Using Afrobarometer 2015, 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. In addition, please comment on what could be influencing the results you obtained. Scenario #3 Is there a relationship between perceptions of current economic conditions and extent of a democracy? Using Afrobarometer 2015, 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. In addition, please comment on what could be influencing the results you obtained.

Moore College of Art and Design Hypothesis Test for a Population Worksheet
ContextA group of 75 college students from a liberal arts college were
randomly sampled and asked about the number of alcoholic drinks they
have in a typical week. The file containing the data is linked below.
The purpose of this study (Links to an external site.) was
to compare the drinking habits of the students at the college to the
drinking habits of college students in general. In particular, the dean
of students, who initiated this study, would like to check whether the
mean number of alcoholic drinks that students at his college have in a
typical week differs from the mean of U.S. college students in general,
which is estimated to be 4.73.VariablesThe number of alcoholic beverages a student consumes in a week.Data: Hypothesis test results:

0.0717PromptThe drinks datafile is available in the Data section below.Let
μ
be the mean number of alcoholic beverages that students
in the liberal arts college drink in a typical week. State the
hypotheses.
Here is a histogram of the data. Can we safely use the t-test with this data? Explain.
Perform the t-test using StatCrunch. (directions)Copy and paste the information from the StatCrunch output window into your initial post.Based on the P-value, state your conclusions in context. Use a 5% level of significance. NOTE: You do not need to double the P-value for this two-tailed test. StatCrunch calculates the P-value for you.Using the context of this scenario, explain the meaning of each of
following items from the StatCrunch output for the hypothesis test.
Std. Err (standard error)T-stat (T-score)P-valueEXAMPLE TO ANSWER 1. The hypotheses are:Ho:
μ
= 4.73Ha:
μ
≠ 4.732. Although the histogram is skewed to the right, we can still do a t-test because n=75 which is more than 30.3.One sample T hypothesis test:μ : Mean of variableH0 : μ = 4.73HA : μ ≠ 4.73Hypothesis test results:

4. 2(0.0717)= 1.4341.434>0.05We do not have enough evidence to reject the null hypothesis that the
average amount of alcoholic beverages that students at this college
drink is the same as the national average.5. a) Std. Err. is the standard error, which is an estimate of how far from the actual mean a sample mean is likely to be.b) T-stat is T-score, which is used in a t-test to find evidence/lack
of evidence of a significant difference between population means.c) The P-value measures the likelihood of getting results as extreme
as the sample in a population where the null hypothesis is true.
