Box Plots Review

Front

What is a Box Plot?

Back

A Box Plot, or Box-and-Whisker Plot, is a graphical representation of a data set that displays its minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

What does IQR stand for?

Back

IQR stands for Interquartile Range, which is the difference between the first quartile (Q1) and the third quartile (Q3) in a data set.

Front

How do you calculate the IQR?

Back

To calculate the IQR, subtract the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

Front

What is the median in a data set?

Back

The median is the middle value when the data set is ordered from least to greatest. If there is an even number of observations, the median is the average of the two middle numbers.

Front

What do the points B and D represent on a box plot?

Back

Points B and D represent the Upper Quartile (Q3) and Lower Quartile (Q1) respectively.

Front

What is the Lower Extreme in a box plot?

Back

The Lower Extreme is the smallest value in the data set, represented by the leftmost point of the box plot.

Front

What is the Upper Extreme in a box plot?

Back

The Upper Extreme is the largest value in the data set, represented by the rightmost point of the box plot.

Front

What does the box in a box plot represent?

Back

The box in a box plot represents the interquartile range (IQR), which contains the middle 50% of the data.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is to provide a visual summary of the distribution of a data set, highlighting its central tendency and variability.

Front

How can you identify outliers in a box plot?

Back

Outliers in a box plot are typically represented as individual points that fall outside the whiskers, which extend to 1.5 times the IQR from the quartiles.
