How do you calculate the median in a Box and Whisker Plot?

Back

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

What does the whisker in a Box and Whisker Plot indicate?

Back

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

What is an outlier in the context of Box and Whisker Plots?

Back

An outlier is a data point that lies significantly outside the range of the other data points, often defined as being more than 1.5 times the IQR above Q3 or below Q1.

Front

How can you determine the IQR from a Box and Whisker Plot?

Back

The IQR can be determined by subtracting the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

How do you interpret the quartiles in a Box and Whisker Plot?

Back

Q1 represents the 25th percentile, Q2 (median) represents the 50th percentile, and Q3 represents the 75th percentile of the dataset.
