What is a box and whisker plot?
All the points listed on a box and whisker plot.
What is the minimum, 1st quartile, median, 3rd quartile, and maximum?
A measure of center of the data.
What is central tendency?
The standard deviation tells me this about the data.
What is the spread of the data?

The box and whisker plot tells you this about the data.
What is the spread and central tendency of the data?
A measure of how far apart each data point is on average.
What is the spread of the data?
Find the standard deviation using the following variance
variance= 25
standard deviation= 5
The population was selected by drawing random names out of a hat
What is simple random?
A class is asked their favorite pizza topping. Create a circle graph with percentages using the data below.
Pepperoni- 8 Sausage- 4 Cheese- 5 Supreme- 3
Pepperoni- 40% Sausage- 20%
Cheese- 25% Supreme- 15%
