Box and Whisker Plots

Front

What is a Box and Whisker Plot?

Back

A Box and Whisker Plot is a graphical representation of a dataset that displays its minimum, first quartile, median, third quartile, and maximum.

Front

What does the median represent in a dataset?

Back

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

Front

How do you find the median of a dataset?

Back

To find the median, arrange the numbers in order and identify the middle number. If there is an even number of values, the median is the average of the two middle numbers.

Front

What do the whiskers in a Box and Whisker Plot represent?

Back

The whiskers represent the range of the data, extending from the minimum to the maximum values.

Front

What is the first quartile (Q1)?

Back

The first quartile (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What is the third quartile (Q3)?

Back

The third quartile (Q3) is the median of the upper half of the dataset, representing the 75th percentile.

Front

How do you calculate the range of a dataset?

Back

The range is calculated by subtracting the minimum value from the maximum value.

Front

What does point C on a Box and Whisker Plot typically represent?

Back

Point C represents the median of the dataset.

Front

What is the significance of outliers in a Box and Whisker Plot?

Back

Outliers are values that fall significantly outside the range of the rest of the data and can affect the interpretation of the dataset.

Front

How can you identify outliers in a Box and Whisker Plot?

Back

Outliers can be identified as points that lie beyond 1.5 times the interquartile range (IQR) from the quartiles.
