Interpreting Visuals [7.SP.4]

Which is true of every box plot?

• Both sides of the box are the same size

• The distance between the min and Q1 is the same as the distance between Q3 and the max

• About half of the data is captured by the box

• The median is one half of the maximum

Answer explanation

When data is skewed in different directions, the sides of the box might be a different size, Q3, Q1 or even the median could be shifted left or right on the number line.

These histograms compare the weights of football players in two universities. Which statements are true?

• The mean weight is larger at Mount Union (blue)

• The ellipsis (squiggly) on the bottom of each graph signals there is no data until the first tick mark

• Mount Union (blue) has more players than Alabama (green)

• All of the Alabama players (green) have more mass than all of the Mount Union players (blue)

Answer explanation

In a histogram or graph with large skips in the data, it is important to note it rather than making the marks on the graph unevenly spaced. It's part of accurately labeling a graph!
