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 shows its minimum, first quartile, median, third quartile, and maximum.

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.

Front

How do you calculate the range of a dataset?

Back

The range is calculated by subtracting the minimum value from the maximum value in the dataset.

Front

What is the purpose of quartiles in a Box and Whisker Plot?

Back

Quartiles divide the dataset into four equal parts, helping to understand the distribution of the data.

Front

What does the lower quartile (Q1) represent?

Back

The lower quartile (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What does the upper quartile (Q3) represent?

Back

The upper quartile (Q3) is the median of the upper half of the dataset, representing the 75th percentile.

Front

What percentage of data lies between the lower and upper quartiles?

Back

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

Front

How can you determine the interquartile range (IQR)?

Back

The interquartile range (IQR) is calculated by subtracting Q1 from Q3 (IQR = Q3 - Q1).

Front

What does a Box and Whisker Plot indicate about outliers?

Back

Outliers are data points that fall outside of the whiskers in a Box and Whisker Plot, indicating they are significantly lower or higher than the rest of the data.

Front

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

Back

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