Instructions

This week’s lab highlights using graphics, distributions, and tables to summarize and interpret data. Review the video below to gain an overview of this week’s lab assignment.

1. Begin with 10 heights provided to you by your instructor. (Please see the link in the Required Resources above.)
2. 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.
3. Determine the mean and standard deviation forthe 20 values (your instructor’s 10 from Step 1A above plus your 10) by using theWeek 3 Excel Spreadsheet.
4. Post a screenshot of the portion of the spreadsheet that helped you determine these values.
5. How does your height compare to the mean (average) height of the20values? Is your height taller, shorter, or the same as the mean of the sample?

Note: The values in the picture above are NOT the values that you are to use in your lab.

Give some background information on the group of people you used in your study. Use the following questions to guide your answers.

1. How did you choose the participants for your study? What was the sampling method:systematic, convenience, cluster, stratified, simple random?
2. What part of the country did your study take place in?
3. What are the age ranges of your participants?
4. How many of each gender did you have in your study?
5. Identify the population based on the sample gathered. For example, if you sampled people that worked on your floor in the hospital, your population may be all employees at your hospital or if you sampled your neighbors, maybe the population is everyone who lives in your city.
10. Use the Week 5 Excel Spreadsheetfor the following:
    1. Use theEmpirical Ruletab from the spreadsheet. Then, determine the 68%, 95%, and 99.7% values of the Empirical Rule in terms of the20 heightsin your height study.
    2. Post a screenshot of your work from the Week 5 Excel spreadsheet.

    

    1. What do these values tell you? (Example: These values tell me that 68% of the heights in the [name your study population; where did you draw your data from?] will fall between 62.584 inches and 70.916 inches. 95% will…).
    2. Post another screenshot of your work from the Normal Probability tab from the Week 5 Excel spreadsheet.
    3. 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).

    GradingThis activity will be graded based on the Week 5 Lab Assignment Rubric.

    Outcomes
