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.

Front

What does the interquartile range (IQR) represent?

Back

The interquartile range (IQR) represents the range of the middle 50% of the data, calculated as Q3 - Q1.

Front

How do you calculate the interquartile range?

Back

To calculate the interquartile range, subtract the first quartile (Q1) from the third quartile (Q3).

Front

What is the median in a Box Plot?

Back

The median is the middle value of a dataset when it is ordered from least to greatest, represented by the line inside the box of a Box Plot.

Front

What are quartiles?

Back

Quartiles are values that divide a dataset into four equal parts, with Q1 being the first quartile, Q2 the median, and Q3 the third quartile.

Front

What is the Upper Quartile?

Back

The Upper Quartile (Q3) is the median of the upper half of the dataset, representing the 75th percentile.

Front

What is the Lower Quartile?

Back

The Lower Quartile (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What does a Box Plot indicate about data distribution?

Back

A Box Plot indicates the spread and skewness of the data, showing how data points are distributed across different quartiles.

Front

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

Back

The whiskers in a Box Plot extend from the quartiles to the minimum and maximum values, indicating the range of the data.

Front

How can you identify outliers in a Box Plot?

Back

Outliers in a Box Plot are typically represented as individual points that fall outside the range defined by Q1 - 1.5*IQR and Q3 + 1.5*IQR.
