Download Week 5 Lab Notes Support Notes (to be used with actual lab)Open the Weeks 3 and 5 spreadsheets from the Weeks 3 and 5 Lessons OR the Getting Started Module (under the Resources tab) to help you answer the questions below.
Step 1: Gather Data
1a. Use these instructor-provided 10 heights from the Required Resources list above to start your lab.
1b. To add 10 more values to your lab data, survey or measure 10 people to find their heights. Add these heights to the Week 5 Lab Template along with the 10 provided by your instructor.
Determine the mean and standard deviation for the 20 values (your instructor’s 10 from Step 1a above plus your 10) by using the Week 3 Excel spreadsheet (Links to an external site.).
1c. Post a screen shot of the portion of the spreadsheet that helped you determine these values.
1d. How does your height compare to the mean (average) height of the 20 values? Is your height taller, shorter, or the same as the mean of the sample?
Step 2: Give some background information on the group of people you used in your study. Use the following questions to guide your answers.
How did you choose the participants for your study? What was the sampling method: systematic, convenience, cluster, stratified, simple random?
What part of the country did your study take place in?
What are the age ranges of your participants?
How many of each gender did you have in your study?
What are other interesting factors about your group?
Step 3: Use the Week 5 Excel spreadsheet (Links to an external site.) for the following.
1. (Use the Empirical Rule tab from the spreadsheet). Determine the 68%, 95%, and 99.7% values of the Empirical Rule in terms of the 20 heights in your height study.
2. Post a screen shot of your work from the Week 5 Excel spreadsheet.
3. What do these values tell you?
4. Post a screen shot of your work from the Normal Probability tab from the Week 5 Excel spreadsheet.
5. Based on your study results, what percent of the study participants are shorter than you? What percent are taller than you? (Example: If my height is 73 inches, then 20.86% of the relevant population is shorter. The other 79.14%, of course, is taller).
Step 4: Be sure your name is on the Word document, save it, and then submit it under “Assignments” and “Week 5: Lab”.
