Box Plot Basics

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that displays its minimum, first quartile, median, third quartile, and maximum.

Front

What does the upper quartile represent in a box plot?

Back

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

Front

What does the lower quartile represent in a box plot?

Back

The lower quartile (Q1) represents the value below which 25% 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

How do you find the minimum value in a box plot?

Back

The minimum value is the smallest data point in the dataset, represented by the leftmost point of the box plot.

Front

How do you find the maximum value in a box plot?

Back

The maximum value is the largest data point in the dataset, represented by the rightmost point of the box plot.

Front

What is the interquartile range (IQR)?

Back

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

Front

What does a box plot tell you about data distribution?

Back

A box plot provides insights into the data's central tendency, variability, and potential outliers.

Front

What is an outlier in the context of a box plot?

Back

An outlier is a data point that lies significantly outside the range of the other data points, often represented as individual points beyond the whiskers of the box plot.

Front

How can you compare two box plots?

Back

You can compare two box plots by examining their medians, quartiles, and overall spread to understand differences in their distributions.
