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, 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 find the range of a dataset?

Back

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

Front

What are quartiles in a Box and Whisker Plot?

Back

Quartiles are values that divide a dataset into four equal parts, with the first quartile (Q1) being the 25th percentile, the second quartile (Q2) the 50th percentile (median), and the third quartile (Q3) the 75th percentile.

Front

What does the interquartile range (IQR) measure?

Back

The interquartile range (IQR) measures the spread of the middle 50% of the data, calculated as Q3 - Q1.

Front

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

Back

A Box and Whisker Plot shows the central tendency, variability, and potential outliers in a dataset.

Front

How can you identify outliers in a Box and Whisker Plot?

Back

Outliers can be identified as data points that fall below Q1 - 1.5*IQR or above Q3 + 1.5*IQR.

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 range of the data.

Front

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

Back

The median line inside the box represents the middle value of the dataset, indicating where half the data points lie below and half above.

Front

What does a longer box in a Box and Whisker Plot indicate?

Back

A longer box indicates greater variability in the middle 50% of the data.
