Box Plots

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows its minimum, first quartile, median, third quartile, 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 minimum value in a box plot?

Back

The minimum value is represented by the leftmost point on the box plot.

Front

What does the maximum value indicate in a box plot?

Back

The maximum value is represented by the rightmost point on the box plot, showing the highest value in the dataset.

Front

What are quartiles in a box plot?

Back

Quartiles are values that divide a dataset into four equal parts: the first quartile (Q1), median (Q2), and third quartile (Q3).

Front

How is the interquartile range (IQR) calculated?

Back

The IQR is calculated by subtracting the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

Front

What does a box plot tell us about the spread of data?

Back

A box plot visually shows the spread of data by displaying the range, quartiles, and any potential outliers.

Front

What is an outlier in the context of a box plot?

Back

An outlier is a data point that lies significantly outside the range of the other data points, often represented as individual points beyond the whiskers of the box plot.

Front

How can you determine the range of a dataset from a box plot?

Back

The range can be determined by subtracting the minimum value from the maximum value: Range = Maximum - Minimum.

Front

What does the length of the box in a box plot represent?

Back

The length of the box represents the interquartile range (IQR), showing the spread of the middle 50% of the data.
