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 Box and Whisker Plot?

Back

The median is the middle value of a dataset when it is ordered from least to greatest, dividing the data into two equal halves.

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 is the interquartile range (IQR)?

Back

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

Front

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

Back

A longer whisker indicates more variability or spread in the data outside the quartiles.

Front

What percentage of data falls within the interquartile range?

Back

50% of the data falls within the interquartile range (IQR).

Front

How can you determine which Box and Whisker Plot has the highest median?

Back

Compare the median lines in each plot; the plot with the highest median line has the highest median.

Front

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

Back

A skewed Box and Whisker Plot indicates that the data is not symmetrically distributed, with more values on one side.

Front

What is the purpose of a Box and Whisker Plot?

Back

The purpose is to summarize and visualize the distribution, central tendency, and variability of a dataset.

Front

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

Back

The first quartile (Q1) is the 25th percentile, the median (Q2) is the 50th percentile, and the third quartile (Q3) is the 75th percentile.
