For the box plot shown below, which number should go in position $2$2?

A box plot, also known as a box-and-whisker plot, is used to display the distribution of a dataset. It consists of a box representing the interquartile range, which contains the middle 50% of the data, and includes a line within the box that indicates the median value. The plot also shows additional details such as the minimum value, maximum value, lower quartile, and upper quartile.
Median $=$= $47$47
L.Q. $=$= $33$33, U.Q. $=$= $61$61
Least score $=$= $16$16, Greatest score $=$= $71$71

Outcomes

8.PS.2

The student will apply the data cycle (formulate questions; collect or acquire data; organize and represent data; and analyze data and communicate results) with a focus on boxplots.

8.PS.2a

Formulate questions that require the collection or acquisition of data with a focus on boxplots.

8.PS.2b

Determine the data needed to answer a formulated question and collect the data (or acquire existing data) using various methods (e.g., observations, measurement, surveys, experiments).

8.PS.2c

Determine how statistical bias might affect whether the data collected from the sample is representative of the larger population.

8.PS.2d

Organize and represent a numeric data set of no more than 20 items, using boxplots, with and without the use of technology.

8.PS.2e

Identify and describe the lower extreme (minimum), upper extreme (maximum), median, upper quartile, lower quartile, range, and interquartile range given a data set, represented by a boxplot.

8.PS.2g

Analyze data represented in a boxplot by making observations and drawing conclusions
