Follow the instructions found in the Lesson 7 Lab to analyze the 4 variables listed in the Lesson 7 Lab Data Download Lesson 7 Lab Data. You should analyze Variable 1 (Var1) and check your results against the results presented in the Lab. You do not need to discuss Var1, but you will be doing the same analysis for Var2, Var3, and Var4 below.(File attached)
1.What are the mean, median, mode, standard deviation, and range for Var2?
2.How does the graph appear for Var2? Hint: does the distribution appear to be normal, skewed, or something else? Give me a descriiption of the appearance and tell me what it might indicate about the concept that was measured.
3.What are the mean, median, mode, standard deviation, and range for Var3?
4.How does the graph appear for Var3? Hint: does the distribution appear to be normal, skewed, or something else? Give me a descriiption of the appearance and tell me what it might indicate about the concept that was measured.
5.What are the mean, median, mode, standard deviation, and range for Var4?
6.How does the graph appear for Var4? Hint: does the distribution appear to be normal, skewed, or something else? Give me a descriiption of the appearance and tell me what it might indicate about the concept that was measured. (Worth 1 point EXTRA CREDIT)
Then:Print 10 copies of the Final Questionnaire and collect data from yourself and 9 friends or relatives. (Please note: I’m asking you to include yourself because I’d like to ensure that the sample has at least some participants who could fall into the “Yes, I have enrolled in an online college course” group. Normally, researchers do not participate in their own research.) We are going to have several research questions to explore: one having to do with online experience, the second with age, and two questions related to future behaviors (Outcome Questions).
You will then enter your data into the Homework 3 excel spreadsheet Download Homework 3 excel spreadsheet, and upload a copy to this assignment page. I have provided a basic introduction to entering data in excel. See the Lesson 6 Lab Handout – Excel.
