What is a Box Plot?

Back

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

Front

What does the minimum value represent in a Box Plot?

Back

The minimum value is the smallest data point in the dataset.

Front

What is the maximum value in a Box Plot?

Back

The maximum value is the largest data point in the dataset.

Front

What is the median in a Box Plot?

Back

The median is the middle value of the dataset when it is ordered from least to greatest.

Front

What is the term for the median of the lower half of the data?

Back

Lower Quartile (Q1) - it is the median of the first half of the dataset.

Front

What is the term for the median of the upper half of the data?

Back

Upper Quartile (Q3) - it is the median of the second half of the dataset.

Front

How do you calculate the Interquartile Range (IQR)?

Back

IQR = Q3 - Q1, which measures the spread of the middle 50% of the data.

Front

Given the data set 50, 60, 82, 86, 94, 110, what is the IQR?

Back

IQR = 86 - 60 = 26.

Front

If the minimum is 77, Q1 is 79.5, median is 86.5, Q3 is 90.5, and maximum is 99, what is the IQR?

Back

IQR = Q3 - Q1 = 90.5 - 79.5 = 11.

Front

What does a Box Plot visually represent?

Back

A Box Plot visually represents the distribution of data based on a five-number summary: minimum, Q1, median, Q3, and maximum.
