Front

What is a Box and Whisker Plot?

Back

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

Front

What does the Interquartile Range (IQR) represent?

Back

The Interquartile Range (IQR) represents the range of the middle 50% of the data, calculated as the difference between the upper quartile (Q3) and the lower quartile (Q1).

Front

How do you find the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of the data set, which means it is the value that separates the highest 25% of the data from the rest.

Front

What is the minimum value in a data set?

Back

The minimum value is the smallest number in the data set.

Front

What is the maximum value in a data set?

Back

The maximum value is the largest number in the data set.

Front

What does a Box and Whisker Plot show about data distribution?

Back

A Box and Whisker Plot shows the spread and skewness of the data, highlighting the median, quartiles, and potential outliers.

Front

What percentage of data lies between the lower quartile (Q1) and upper quartile (Q3)?

Back

50% of the data lies between the lower quartile (Q1) and upper quartile (Q3).

Front

How do you calculate the Interquartile Range (IQR)?

Back

To calculate the Interquartile Range (IQR), subtract the lower quartile (Q1) from the upper quartile (Q3): IQR = Q3 - Q1.

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 data's central tendency, variability, and overall distribution.

Front

What does it mean if a Box and Whisker Plot is skewed to the right?

Back

If a Box and Whisker Plot is skewed to the right, it indicates that the majority of the data points are concentrated on the left side, with a few higher values stretching the tail to the right.
