Statistics Final Assignment using Statcrunch
Using the data set supplied in StatCrunch, provide the following for the variable(s) of your choice:
- Frequency distribution of a nominal variable (with cumulative relative frequency) and bar graph of the same variable
- Descriptives (summary stats) of a continuous variable: mean, median, skewness, kurtosis, standard deviation and graph of that variable
- Cross tabulation of two variables, with chi square. Include hypotheses and analysis.
- Comparison of the effect of three or more groups (single variable) on a single continuous variable. Include hypotheses and analysis.
- Scatterplot of two continuous variables
- Correlation between the two continuous variables from #5 above, with regression. Include hypotheses and results.
Think carefully about what kind of variables to choose for the given tasks.
A short descriptive statement should accompany each of the above including a description of the variables used and any meaning that may be attached to the results. The student must show that she or he is able to synthesize and apply the materials learned in class. Part of the class time is expected to be spent on this project. Submit to the appropriate assignment area in a Word document.
Grading on this project is as follows:
3 points for each task 1-6: 1 point each for variable choice, appropriate display/test, description of result.
2 points for overall format/readability/construct (the writing and graphs should be formal and of publishable quality as you would see in a journal article)
