What is a box plot?

Back

A box plot is a graphical representation of a data set that shows the median, quartiles, and any outliers.

Front

How do you calculate the mean of these numbers: 5, 11, 2, 12, 4, 2?

Back

Mean = (5 + 11 + 2 + 12 + 4 + 2) / 6 = 36 / 6 = 6.

Front

What is the median of the following numbers: 58, 60, 62, 66?

Back

Median = (60 + 62) / 2 = 122 / 2 = 61.

Front

What is the range of these numbers: 8, 10, 60, 3, 5, 13, 12, 40, 8?

Back

Range = 60 - 3 = 57.

Front

What is the interquartile range (IQR)?

Back

The IQR is the difference between the first quartile (Q1) and the third quartile (Q3) in a data set.

Front

How do you find the mode of the numbers: 1, 2, 2, 3, 4?
