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 values.

Front

What does the median represent in a Box and Whisker 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

What are quartiles in a Box and Whisker Plot?

Back

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

Front

How do you find the lower extreme in a Box and Whisker Plot?

Back

The lower extreme is the smallest value in the dataset.

Front

How do you find the upper extreme in a Box and Whisker Plot?

Back

The upper extreme is the largest value in the dataset.

Front

What does the interquartile range (IQR) represent?

Back

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1), representing the range of the middle 50% of the data.

Front

What percentage of data lies between the first quartile and the third quartile?

Back

50% of the data lies between the first quartile (Q1) and the third quartile (Q3).

Front

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

Back

The whiskers extend from the quartiles to the lower and upper extremes, showing the range of the data outside the interquartile range.

Front

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

Back

The median line within the box indicates the central tendency of the dataset.

Front

How can you determine if a dataset is skewed using a Box and Whisker Plot?

Back

If the median line is closer to one quartile than the other, or if the whiskers are of unequal length, the dataset may be skewed.
