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 lower quartile (Q1) represent in a Box and Whisker Plot?

Back

The lower quartile (Q1) represents the value below which 25% of the data falls.

Front

How do you calculate the median from a Box and Whisker Plot?

Back

The median is the middle value of the dataset, which divides the data into two equal halves.

Front

What does the upper quartile (Q3) represent in a Box and Whisker Plot?

Back

The upper quartile (Q3) represents the value below which 75% of the data falls.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the upper quartile (Q3) and the lower quartile (Q1), representing the range of the middle 50% of the data.

Front

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

Back

A longer whisker indicates a greater spread of data points outside the quartiles.

Front

How can you determine the spread of data from a Box and Whisker Plot?

Back

The spread of data can be determined by looking at the length of the box and the whiskers, as well as the IQR.

Front

What percentage of data falls between Q1 and Q3 in a Box and Whisker Plot?

Back

50% of the data falls between Q1 and Q3.

Front

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

Back

If a Box and Whisker Plot is skewed, it indicates that the data is not symmetrically distributed, with a longer tail on one side.

Front

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

Back

The median is the line inside the box that divides the box into two parts, representing the middle value of the dataset.
