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 (Q1), median, third quartile (Q3), and maximum values.

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, dividing the dataset into two equal halves.

Front

How do you find the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of the dataset, excluding the median if the number of data points is odd.

Front

What is the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of the dataset, excluding the median if the number of data points is odd.

Front

How is the interquartile range (IQR) calculated?

Back

The interquartile range (IQR) is calculated by subtracting the lower quartile (Q1) from the upper quartile (Q3): IQR = Q3 - Q1.

Front

What does the maximum value represent in a Box and Whisker Plot?

Back

The maximum value represents the highest data point in the dataset.

Front

What does the minimum value represent in a Box and Whisker Plot?

Back

The minimum value represents the lowest data point in the dataset.

Front

What percentage of data falls within the interquartile range (IQR)?

Back

Approximately 50% of the data falls within the interquartile range (IQR), which is between Q1 and Q3.

Front

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

Back

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

Front

What is the purpose of a Box and Whisker Plot?

Back

The purpose of a Box and Whisker Plot is to provide a visual summary of the distribution, central tendency, and variability of a dataset.
