When you have a boxplot, what can you look at to determine spread? (variability)
IQR
The box
The range

What is the AVERAGE number of siblings the students have in your group?
Describe the steps you took to get the answer.
answers vary
Students should explain mean/ average and explain either calculating it mentally, with a yellow calculator or with desmos.

Can you find the mean and median of a histogram?
Why or why not?
No- in a histogram you have intervals of data, but not specific data.
