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.
