#### Steps to Complete Week 5 Lab

Step 1: Survey or measure 10 people to find their heights. Determine the mean and standard deviation for this group 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 group that you surveyed? Is your height taller, shorter, or the same as the mean of your group?

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.

1. How did you choose the participants for your study (sampling method)?
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?
