Front

What are the whiskers in a box and whisker plot?

Back

The whiskers extend from the box to the minimum and maximum values of the dataset, excluding outliers.

Front

How do you calculate the interquartile range (IQR)?

Back

IQR is calculated as Q3 - Q1, where Q3 is the third quartile and Q1 is the first quartile.

Front

What does Q1 represent in a box and whisker plot?

Back

Q1, or the first quartile, represents the value below which 25% of the data falls.

Front

What does Q3 represent in a box and whisker plot?

Back

Q3, or the third quartile, represents the value below which 75% of the data falls.

Front

What is the median in a box and whisker plot?

Back

The median is the middle value of the dataset, dividing it into two equal halves.

Front

How can you identify outliers in a box and whisker plot?

Back

Outliers are typically identified as values that fall below Q1 - 1.5*IQR or above Q3 + 1.5*IQR.

Front

What percentage of data lies between Q1 and Q3?

Back

50% of the data lies between Q1 and Q3.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset.
