What is a Box Plot?

Back

A Box Plot is a graphical representation of a dataset that displays the distribution of data based on five summary statistics: minimum, lower quartile (Q1), median (Q2), upper quartile (Q3), and maximum.

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

Back

The lower quartile (Q1) represents the median of the lower half of the dataset, meaning 25% of the data points are below this value.

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

Back

The upper quartile (Q3) represents the median of the upper half of the dataset, meaning 75% of the data points are below this value.

What is the median in a Box Plot?

Back

The median (Q2) is the middle value of the dataset when it is ordered from least to greatest, dividing the dataset into two equal halves.

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.

What does the IQR tell us about a dataset?

Back

The IQR measures the spread of the middle 50% of the data, indicating how concentrated the data points are around the median.

What is the purpose of a Box Plot?

Back

The purpose of a Box Plot is to visually summarize the distribution of a dataset, highlighting its central tendency and variability.

What does a Box Plot indicate about outliers?

Back

Outliers are data points that fall significantly outside the range of the Box Plot, typically defined as being 1.5 times the IQR above Q3 or below Q1.
