o------------[o-----------o------o]----o
1 2 3
a. 1
b. 2
c.3
What is B?

Mean is another word for average.
Find the IQR
median - 13
Q1- 7
Q3- 20
mean- 14.1
What is 13?
to find IQR do Q3-Q1 or 20-7 and you get 13.
Can you find the mean without knowing how many numbers you have?
What is no?
You need to know the amount of numbers because you use that number to divide into the total.
