# Statistics - Program Evaluation, Coursework

1) Test whether there is an association between a person’s gender and the prestige of their occupation. Use the GSS2008 data set to perform an independent samples t-test on SEX and PRESTG80. Mean prestige score for men ___________________ Mean prestige score for women ___________________ t-test equality of means significance level (sig.) ___________________ Is the relationship statistically significant (sig.) Yes No On the basis of these data, would you say that gender is associated with occupational prestige? What could explain this relationship? 2) Perform a paired t-test to compare the White State Prisoner Incarceration Rate per 100,000: 2005 (CRC66) to the Black State Prisoner Incarceration Rate per 100,000: 2005 (CRC67) using the STATES10 data set. White State Prisoner Incarceration Rate per 100,000: 2005? __________________ Black State Prisoner Incarceration Rate per 100,000: 2005? __________________ Significance (sig.) for the Paired Samples Test? ___________________ Is the relationship statistically significant Yes No Are incarceration rates related to race? What were you expecting to find and did you find it? 3) Astrologers assert that our birth dates influence our success (or lack thereof) in life. Test this assumption with the GSS2008 data by analyzing the relationship between respondent’s astrological sign (ZODIAK) with respondent’s socioeconomic index (SEI). The SEI is an indicator of economic and socio-economic attainment: The higher the SEI score, the more successful the respondent. Make a prediction: Can a person’s astrological sign predict their socioeconomic success? Yes No If so, what zodiac sign is the most successful ____________ Now perform the analysis using the GSS2008 data Mean SEI10 of Pisces ______________ Mean SEI10 of Taurus ______________ Mean SEI10 of your astrological sign ______________ ANOVA significance level ______________ Is the relationship statistically significant? Yes No On the basis of these data, would you say that astrologers are correct in their assertion of the power of the stars? Why? 4) Hi all, I would recommend taking a look at assignment 2 (exercise 2)--we are going to practice this exercise Test whether there is an association between a person’s educational attainment and how much television they watch. Use the GSS2008 data set to perform an ANOVA on respondents’ highest educational degree (DEGREE) and the hours per day they watch television (TVHOURS) Now perform the analysis with PSPP [USE THE SYNTAX BELOW TO DO THE ENTIRE ANALYSIS] and find: WE WILL USE THIS TO DO THE FOLLOWING QUESTIONS: One-way ANOVA File New Syntax The syntax editor will open, then type [do not type anything in red, they are commands] Oneway [enter] /Variables = var1 BY var2 [enter] /Statistics = descriptives [enter] /Posthoc = tukey [go to tool ribbon “File Edit Run Windows Help” and click on RUN and then ALL. Check you output and you should have a nice TABLE. Var1 and var2 are the variables being used for the tables. Just type in the variable name as written in the assignment.]. Hint on the above Tvhours BY degree Mean hours for people with less than a high school degree Mean hours for people with a high school degree Mean hours for people with a junior college degree Mean hours for people with a bachelor’s degree Mean hours for people with a graduate degree ANOVA significance level Is the relationship statistically significant THE TUKEY TEST ALLOWS US TO SEE IF THERE IS A SIGNIFICANT DIFFERENCE AMONG THE DIFFERENT GROUPS, FOR EXAMPLE: According to the Tukey Test, which categories have means that are significantly different from the means of those with a high school degree? SO YOU CHECK THE ROW "HIGH SCHOOL" IN THE TUKEY TEST BOX (MULTIPLE COMPARISONS), AND DO YOU SEE ANY CATEGORIES THAT ARE SIGNIFICANTLY DIFFERENT? WHICH ONE?
1) Test whether there is an association between a person’s gender and the prestige of their occupation. Use the GSS2008 data set to perform an independent samples t-test on SEX and PRESTG80.
