Box Plots

Front

What is a box plot?

Back

A box plot, or box-and-whisker plot, is a graphical representation of a dataset that displays its minimum, first quartile (Q1), median, third quartile (Q3), and maximum values.

Front

What does the median represent in a box plot?

Back

The median is the middle value of a dataset when it is ordered from least to greatest, dividing the dataset 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 significance of the whiskers in a box plot?

Back

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

Front

What does Q1 represent in a box plot?

Back

Q1, or the first quartile, represents the value below which 25% of the data falls.

Front

What does Q3 represent in a box plot?

Back

Q3, or the third quartile, represents the value below which 75% of the data falls.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in a dataset.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in a dataset.

Front

How can you identify the median from a box plot?

Back

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

Front

What does a longer box in a box plot indicate?

Back

A longer box indicates a larger interquartile range (IQR), suggesting more variability in the middle 50% of the data.
