Box Plots

Front

What is a Box Plot?

Back

A Box Plot, also known as a 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 IQR stand for?

Back

IQR stands for Interquartile Range, which is the difference between the first quartile (Q1) and the third quartile (Q3) in a dataset.

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 does the median represent in a Box Plot?

Back

The median represents the middle value of a dataset when it is ordered from least to greatest.

Front

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

Back

50% of the data falls between Q1 (first quartile) and Q3 (third quartile) in a Box Plot.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset.

Front

How can you identify outliers in a Box Plot?

Back

Outliers can be identified as points that fall outside of the whiskers, which typically extend 1.5 times the IQR above Q3 and below Q1.

Front

What does a longer whisker indicate in a Box Plot?

Back

A longer whisker indicates a greater spread of data points in that direction, suggesting more variability.

Front

What is the significance of the first quartile (Q1)?

Back

Q1 is the value below which 25% of the data falls.
