You need to make sure this answer is in complete sentences and that you make mention of things like MEDIAN, MODE, RANGE, and at least one other observation you can make about the data.
Compare and contrast the data displays you created for a boxplot, histogram, and stem and leaf.
What does a histogram show that the others don't?
What does a boxplot show that the others don't?
What does a stem and leaf show that the others don't?
What do they all have in common?
Which do you think is the BEST way to display your data? Explain why.
You must write in complete sentences and give complete thoughts with statistical analysis.

Standard deviation:
Use the show your work area to draw a WELL LABLED Normal Curve.
Show the empirical rule.
a) What is your value within the data?
b) What is the z-score of your value?
c) What percent of scores are above your score?
d) Are there any values that are unusual?
e) What is the Q1 of your data set?
f) What percent of data values are between your score and the Q1.
Show your work for the answer to question (c) in the show your work area.
According to your normal model....
68% of the data should fall between the values of
95% of the values should fall between the values of
99.7% of the values should fall between the values of
EXTENSION....
Look at your histogram....and then think about your data set.
Using your histogram as part of your discussion, do you think your calculations to find your z-score are accurate? Why or why not?
(this should be at least a 2-4 sentence answer)
