Box Plot

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 the lower quartile (Q1) represent in a Box Plot?

Back

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

Front

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

Back

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

Front

What is the median in a Box Plot?

Back

The median is the middle value of the dataset, dividing it into two equal halves.

Front

What is the purpose of the whiskers in a Box Plot?

Back

The whiskers extend from the box to the smallest and largest values that are not outliers, showing the range of the data.

Front

How do you calculate the interquartile range (IQR)?

Back

The interquartile range (IQR) is calculated by subtracting the lower quartile (Q1) from the upper quartile (Q3): IQR = Q3 - Q1.

Front

What does an outlier represent in a Box Plot?

Back

An outlier is a data point that is significantly higher or lower than the other values in the dataset, often represented as individual points beyond the whiskers.

Front

What percent of data falls below the median in a Box Plot?

Back

50% of the data falls below the median in a Box Plot.

Front

If the lower quartile is 40, what does this indicate about the data?

Back

This indicates that 25% of the data points are less than or equal to 40.

Front

What is the significance of the upper extreme in a Box Plot?

Back

The upper extreme represents the maximum value in the dataset, excluding outliers.
