Statistical Reasoning

Varalakshmi Balaji, Instructor

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?

Measure of Central Tendency and Variation:

In my survey I am utilizing random sampling and a numerical variable as I’m studying

the height of 10 out of 50 nurses. It is a convenience sample as I chose to sample the

nurses where I work, and the data is quantitative continuous since it is numerical and

can have fractions. The location was Tyler, TX. All nurses were in work-from-home

positions. They come into the physical corporate office approximately 3 times a year for

meetings.
