Steps to Complete Week 5 Lab
Use the Weeks 3 and 5 spreadsheets from the Weeks 3 and 5 Lessons to help you answer the questions below.
Step 1: Your instructor will provide you with 10 values to use for this lab.
Gather 10 MORE of your own to add to the 10 provided by your instructor. Do the following:
Survey or measure 10 people to find their heights. Determine the mean and standard deviation for the 20 values by using the Week 3 Excel spreadsheet. Post a screen shot of the portion of the spreadsheet that helped you determine these values. 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?
Note: The following image is just an example. They are NOT the values you should be using for your lab. Your instructor should have sent you our data values for your Week 5 Lab. Please reach out to your instructor if you do not have your data values.
Data Example of 10 people with different heights(your spreadsheet will have 20 values—10 from your instructor and 10 from your own data gathering).Step 2: Give some background information on the group of people you used in your study. You might consider using the following questions to guide your answer.
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 for the following.
(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.
What do these values tell you?
Post a screen shot of your work from the Week 5 Excel spreadsheet.
(Use the normal probability tab from the spreadsheet). Based on your study results, what percent of the study participants are shorter than you? What percent are taller than you?
Post a screen shot of your work from the Week 5 Excel spreadsheet.
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”.
REQUIREMENTS
The deliverable is a Word document with your answers to the questions posed below based on the data you find.
REQUIRED SOFTWARE

GRADING
This activity will be graded based on the Week 5 Lab Rubric.
OUTCOMES
CO 3: Given scenarios supported by qualitative and quantitative data, summarize, organize, display and interpret data through the application of graphs generated with the use of technology.
Week(s): 2, 8
CO 4: Given scenarios using quantitative data from everyday life, calculate and interpret numerical summaries such as measures of central tendency, measures of variation, and measures of position.
CO 5: Given a normally distributed dataset or creating such a dataset, describe, apply, and interpret the principles and its application with everyday decisions.

Instructor Name: _______________
Please use this template to help answer the questions listed in the lab
instructions. The “steps” below refer to the steps listed in the lab instructions.
Type your answers and post your screenshots in the spaces given below. Then,
save this document with your name and submit it inside the course room.
Step 1. Gather Data
Your instructors will post 10 data values to use for this lab. The data values
represent the HEIGHTS of 10 people.
Please reach out to your instructor if you did not receive the assigned 10 data
values for the term by Monday of Week 5.
(NOTE: This is NOT the data used in the lab video, which is about midterm
grades. Do not use the midterm grades data.)
1a. Gather 10 MORE of your own to add to the 10 provided by your instructor.
Do the following: Survey or measure 10 people to find their heights. Determine
the mean and standard deviation for the 20 values by using the Week 3 Excel
spreadsheet. (Round statistics to two decimals.)
Mean Height in Inches
Sample Standard Deviation

1b. Post a screen shot in the space BELOW of the portion of the spreadsheet
that helped you determine these values. Please list the 10 heights your
professor provided first followed by the 10 heights you collected. There
should be 20 values to determine the mean and sample standard deviation.
1c. Answer the following two questions (Answer in complete sentences).
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?
