Statistics

For  this assignment, you will use a secondary dataset (e.g., data that has  already been collected by another source) to demonstrate your skills in  the basics of statistical analyses. You will need to:  

1. Describe your research question.
2. State a hypothesis.
3. List  and explain the variables you are using from the dataset. Should you  design a study with just two variables, make a recommendation for a  third variable and how that might add to interpretation of the data.
4. Select  a random sample of data from your dataset. The data should have a  minimum of 30 cases, but not more than 200 cases. (Hint: You can use the  “random” function in either Excel or SPSS to generate a random sample  from your dataset.)
5. Conduct a descriptive data analysis that includes the following: 
   1. a measure of central tendency
   2. a measure of dispersion
   3. at least one graph
6. Briefly interpret the descriptive data analysis.
7. Conduct  the appropriate statistical test that will answer your hypothesis. It  must be a statistical test covered in this course such as regression  analysis, single t-test, independent t-test, cross-tabulations,  Chi-square, or One-Way ANOVA. Explain your justification for using the  test based on the type of data and the level of measurement.
8. Report  and interpret your findings. Use APA style and include a statement  about whether you reject or fail to reject the null hypothesis. Here are  some resources that will help you with APA formatting in this step: 
   1. Reporting Statistics in APA Style
   2. Reporting Results of Common Statistical Tests in APA Format
9. Copy and paste your Excel or SPSS data output and place it in an appendix.

Length: 10-15 pages
 

 Your response should demonstrate thoughtful consideration of the ideas  and concepts presented in the course and provide new thoughts and  insights relating directly to this topic. Where applicable, your  response should reflect scholarly writing and current APA standards.
