Mr. Salso will check.
Is the following question statistical or not?

What is 19 and 18!
Definition of range!
The range math definition is the difference between the highest value and the lowest value in a given set of numbers.
Give me an easy definition of what a histogram is.
What is a histogram is a graph that shows the frequency of numerical data using rectangles.
Make a stem and leaf plot out of the data!

MR.SASLORD WILL CHECK!!!

LET MR. SASLO CHECK YOUR HISTOGRAM!!!
What is the shape of the data out of the data below.
1,4,2,4,3,3,2,4,2,4,5,6
What is symmetrical
Two data sets have the same range. Can you assume that the IQRs of the two data sets are about the same? Give an example, IF YOU DO NOT GIVE AN EXAMPLE YOU WILL NOT GET THE POINTS!!!
What is NO!!!
Make a dot plot and see what the best measure of center is?
1,1,1,3,5,6,6,8,8,8,8,4,2

What is the Mad of...
10,8,10,6,6,2,10,4
What is 2.5
Make up your own data and make a histogram out of it
Show Mr.Saslord
Everybody make a stem-and-leaf plot(don't forget the key) Make it hard but not impossible! When everybody is done switch with somebody and find all of the measures of center and all the measures of variation.
What is let Mr.Saslo check your work
Take the data below and make a dot plot,box and whisker, and stem-and-leaf (don't froget keys and labels)
