Description

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 from the same population in which you gathered your sample.

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. For the remainder of this lab, treat the 20 numbers as ONE sample.

1b. Post a screen shot in the space BELOW of the portion of the Week 3 spreadsheet that helped you determine these values. Please list the 10 heights your professor provided first followed by the 10 heights you collected.

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?

Step 2. Data Characteristics

Answer the following questions to give some background information on the group of people you used in your study. Write in complete sentences.

How did you choose the participants for your study? What was the sampling method: systematic, convenience, cluster, stratified, simple random, etc.? Explain how you concluded that you used the selected sampling method.
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?

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.

Step 3. Data Analysis

Answer the following questions. Use the Week 5 Excel spreadsheets to help analyze the data.

For the remainder of the lab, suppose the population has the same mean and standard deviation as your sample.

Empirical Rule

Determine the 68%, 95%, and 99.7% values of the Empirical Rule using the population mean and standard deviation. (Use the Empirical Rule tab from the Week 5 spreadsheet).
Take a Screenshot of your Empirical Rule Sheet and provide it below.
What do these values tell you? Write complete sentences explaining what the values in the Empirical Rule tell you in context of the data.

Step 4. Save and submit this document
