Read instructions to each section carefully to understand what type of response you should be giving. This should illustrate that you completed the work yourself and using SPSS.
Part A – Independent-samples T-tests
In this section, you will conduct independent-samples t-tests using a continuous/scale variable as your test/outcome/dependent variable and a categorical variable as your independent/grouping variable. Practice writing your results professionally as sentences in the space below (the book and the presentation give examples. Your text should present:
Distribution of the continuous variable for the values of your categorical variable .
95% confidence interval for the difference of the means.
t-value, df, effect size , and significance level .
Warning that not all information is given by SPSS and you may have to calculate items manually using the output.
For the quiz, copy directly from the output; do not round and do not add or remove extra zeros. If p-value=.000, then report “<.001”. If eta-squared is less than .001, then report “<.001”; otherwise, round to 3 decimals.
Using the Cholera and Distance variables
Using the Cholera and Age variables.
Using the Town Type and Distance variables.
Part B – Chi-square tests for Independence
In this section, you will conduct chi-square tests for independence using Crosstab frequencies and two categorical variables. Practice writing your results professionally as sentences in the space below (the book and the presentation give examples). Your text should present:
Information about the distribution of the two variables. (It is useful to request Observed Counts (Ns) and Row/Column Percentages to help with this.)
Chi-square test value, df, significance level (p-value), and effect size (Phi or Cramer’s V).
Warning that not all information is given by SPSS and you may have to calculate items manually using the output.
For the quiz, copy directly from the output; do not round and do not add or remove extra zeros. If p-value=.000, then report “<.001”. Choose appropriate measure between Phi or Cramer’s V.
Using TownID and Sex variables; focus on proportion of males within each town.
Using EdProgram and Cholera; focus on proportion of cholera within education program.
Using EdProgram and Cholera stratified by TownType; focus on proportion of cholera within education program with urban/rural status.
Part C – Evaluation of Education Program on Cholera
Using the results from Part B questions 2 and 3 above, you need to evaluate the effectiveness of the education program on cholera in the communities. Calculate the Risk Ratio and Risk Difference. You need to assess the potential of confounding and effect modification by whether the town was urban vs. rural. Note: you may have to reorder the output when calculating the RR and RD below—treat education programs with the town hall as the exposed group and cholera as the disease group.
Show 3 decimals for the below calculations.
Crude or Overall RR.
Crude or Overall RD.
Urban RR.
Urban RD.
Rural RR.
Rural RD.
Overall, does the education program with the town hall meetings result in a difference in cholera compared to the education program only?
Which measure Risk Ratio or Risk Difference provides the best information for public health policy changes?
Which measure Risk Ratio or Risk Difference provides the best information for the magnitude of the association?
