Flashback Box and Whiskers

Front

What is a box and whisker plot?

Back

A 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 values.

Front

What does the median represent in a data set?

Back

The median is the middle value of a data set when it is ordered from least to greatest. It divides the data into two equal halves.

Front

How do you find the interquartile range (IQR)?

Back

The interquartile range (IQR) is found by subtracting the first quartile (Q1) from the third quartile (Q3). IQR = Q3 - Q1.

Front

What is the maximum value in a data set?

Back

The maximum value is the largest number in a data set.

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of a data set, representing the 25th percentile.

Front

What is the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of a data set, representing the 75th percentile.

Front

How do you determine the median from a box and whisker plot?

Back

The median is represented by the line inside the box of the box and whisker plot.

Front

What does the whisker represent in a box and whisker plot?

Back

The whiskers in a box and whisker plot extend from the box to the minimum and maximum values, showing the range of the data.

Front

What is the purpose of a box and whisker plot?

Back

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

Front

How can you identify outliers in a box and whisker plot?

Back

Outliers can be identified as points that fall outside the range defined by 1.5 times the IQR above Q3 and below Q1.
