Statistics

Part A

For Part A you will choose a topic for your project. You will need to determine the number of mean for your topic. You will submit Part 1 in Unit 2.

Here are some examples of topics with 1 mean:

·        

Is the mean SAT math score for some defined population 500?

·         Is the mean starting salary for an associate’s student $28,000?

·         Is the mean number of students who have full time jobs 60% of your school’s total population?

Examples of topics with 2 means:

·         Is the mean number of Networking students (or any degree program) different for males and females?

·         Is there a difference in the mean salary of individuals given that they have completed no more than high school or 2 years of college?

·         Is the mean number of students who like Pepsi different from the mean number of students who like Coke?

Part B

In Part B you will submit a “working” References page containing the source or sources for your project. Use APA to create your Reference page. Additionally, if you choose to create a survey, submit your list of questions.

Part C

In Unit 4 you will create and submit the graphs, hypothesis and test conclusions for your project. Please be sure to show your work.

Part D

In Unit 5 you will complete your final project. Your final project should include the following:

·         Sampling: A careful description of how you obtained the samples. Be very specific. Include sample sizes, population of interest, and description of sample. Also include a copy of the survey if you used one.

·         Data: The actual data and a summary of the counts.

·         Descriptive Statistics: Any descriptive statistics relevant to your project should be included. You are required to give mean, mode, median, and standard deviation of your data (2 sets if you are doing 2 means). At least two graphs (such as box plots, scatter plots, stem-and-leaf, histograms, etc.) should be part of your project. The graphs can be a way to summarize descriptive statistics.

·         Hypothesis Test: The type of test should be identified and an explanation of why this type of test was chosen. Your project should include a check to make sure that it meets the assumptions of the particular test. This may include a graph. The hypotheses should be stated in words and symbols. The formula should be written with symbols and then with the substitution of the appropriate numbers.

·         Conclusion: Discuss the weaknesses of your study. Include any confounding variables. To what population do you feel comfortable extrapolating your results? Why? Give suggestions for further work in the area of your topic. Be sure to reference the situation as you discuss your conclusion. Explain what lead you to the conclusion(s) that you have drawn.
