How do you find the median?
What is find the middle number. First place the numbers in order from least to greatest. If the number of data is odd, it is the middle number. If the number of data is even, find the two middle numbers and find the mean.
200
When the median used as the best value to use for a dot plot or box and whisker?
What is when the data is skewed.

What is Q1 - ( IQR x 1.5).
300
In a dot plot, if the data set is skewed to the right, where is most of the data?
What is left.
300
If the box and whisker is skewed to right, what would be the best measure of center for the data?
What is median.
300
What percent of the data is above the maximum?
What is 0%.
300
When is the mean the best value to use for a dot plot and box and whisker?
What is data is symmetric.
300
What is the formula for the upper fence?
What is Q3 + ( IQR x 1.5).
400
Describe the distribution of the data set on a dot plot, what does that mean?
What is if the dot plot is skewed to left, symmetric, or skewed to right.
400
If 5 is the median of the box and whisker, what does the number represent?
What is 50% of the data is above or below 5.

How do you know if there are any outilers?
What is numbers less than the lower fence and numbers greater than the upper fence.
500
Would 2,4,4,5,7,8 have outiler?
What is none.

What can the box and whisker not tell you about the data?
What is how many scored a number, who scored what....
