Download and save the Polit2SetA.sav data set. You will open the data file in SPSS.Compare your data output against the tables presented in the Week 4 Descriptive Statistics SPSS Output document. This will enable you to become comfortable with defining variables, entering data, and creating tables and graphs.Formulate an initial interpretation of the meaning or implication of your calculations.To complete:Complete the Part I, Part II, and Part III steps and Assignment as outlined in the Week 4 Descriptive Statistics Assignment page.Part IUsing the Polit2SetA data set, run descriptive statistics on the following variables: respondent’s age (age) and highest school grade completed (higrade). Create a frequency distribution for the variables: race and ethnicity (racethn) and currently employed (worknow). Create a table (in APA format) summarizing the results, using the below table shell as a model. Write a paragraph summarizing the information in the table.Table 1. Demographic Data (N= 30)n% M (SD)Age (in years)     30  15(2.4)Highest School Grade Completed  29  11(1.2)Race and EthnicityBlack, Not Hispanic    14 (46.67)Hispanic       8 (26.67)White, Not Hispanic      6 (20.0)Other        2 (6.66)Currently EmployedYes      27 (90)No        3 (10)Note.Differences in sample size are due to missing data.Follow these steps when using SPSS:1. Open Polit2SetA data set.2. Click onAnalyze,then click onDescriptives Statistics, thenDescriptives.3. Click on the first continuous variable you wish to obtain descriptives for (respondent’s age), and then click on the arrow button and move it into the Variables box. Then click onhighest school grade completedand then click on the arrow button and move it into the Variables box.4. Click on theOptionsbutton in the upper-right corner. Click onmean,standard deviation,minimum,maximum, andskewness.5. Click onContinueand then click onOK.To run the frequency distribution in SPSS, do the following:1. Click onAnalyze, then click onDescriptive Statistics, thenFrequencies.2. Click on the first categorical variable you wish to obtain a frequency for (race and ethnicity), and then click on the arrow button and move it into the Variables box. Then click oncurrently employed,and then click on the arrow button and move it into the Variables box. Click on theStatisticsbutton in the upper-right corner, then in the Dispersion box click onMinimum and Maximum.3. Click onContinueand then click onOK.Assignment:Create a table (in APA format) summarizing the results, using the below table shell as a model. Write a paragraph summarizing the information in the table.Part IIFor the variables respondent’s age (age) and highest school grade completed (higrade) create a histogram with a normal curve displayed over the histogram.To create a histogram for respondent’s age in SPSS, do the following:1. Click onGraphs, then onLegacy Dialogs, thenHistogram.2. Click on the variablerespondent’s ageand then click on the arrow button and move it into the Variables box. Click on theDisplay Normal Curvebutton, which is right below the Variables box.3. Click onOK.To create a histogram for highest school grade completed in SPSS, do the following:1. Click onGraphs, then onLegacy Dialogs, thenHistogram.2. Click onrespondent’s agein the Variable box and click the arrow to move it back to the box on the left that contains all the variables.3. Click on the variablehighest school grade completedand then click the arrow button and move it into the Variables box. TheDisplay Normal Curvebutton should alredy be on.4. Click onOK.Assignment:Using the data obtained when you ran the descriptives and the histograms, determine whether the data skewed. If so, is it a positive or negative skew?Part IIIUsing the Polit2SetA data set, run descriptive statistics on the variable “Family Income Prior Month, all sources” (Income).Follow these steps when using SPSS:1. Click onAnalyze, then click onDescriptives Statistics, thenDescriptives.2. Click onFamily Income Prior Month, all sources, and then click on the arrow button and move it into the Variables box.3. Click on theOptionsbutton in the upper-right corner. Click onmean,standard deviation,minimum,maximum,S.E. Mean(standard error of the mean), andskewness.4. Click onContinueand then click onOK.Assignment:Using the descriptive statistics for Family Income Prior Month, all sources (Income), answer the following questions:1. What is the mean income in this sample?2. What is the standard deviation?3. What is the standard error of the mean?4. Compute a 95% confidence interval around the mean. (Use 1.96 for the 95% CI and get the standard error from the descriptive statistics table). The formula is as follows:95% CI = [mean ± (1.96 ´ SE)]5. Compute a 99% confidence interval around the mean. (Use 2.58 for the 99% CI and get the standard error from the descriptive statistics table). The formula is as follows:99% CI = [mean ± (2.58 ´ SE)]6. Which interval is wider? Explain.Review the corresponding Week 4 Descriptive Statistics Exercises SPSS Output document that has the SPSS output for the above problems.
