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 median represent in a dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. It divides the dataset into two equal halves.

Front

How do you find the median of a dataset?

Back

To find the median, arrange the numbers in ascending order and locate the middle number. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is the mode of a dataset?

Back

The mode is the value that appears most frequently in a dataset. A dataset may have one mode, more than one mode, or no mode at all.

Front

How do you determine the mode from a set of numbers?

Back

Count how many times each number appears in the dataset. The number that appears the most is the mode.

Front

What is the range of a dataset?

Back

The range is the difference between the maximum and minimum values in a dataset.

Front

How do you calculate the range of a dataset?

Back

To calculate the range, subtract the smallest number (minimum) from the largest number (maximum) in the dataset.

Front

What is a quartile in statistics?

Back

A quartile is a type of quantile that divides a dataset into four equal parts. The first quartile (Q1) is the median of the lower half, the second quartile (Q2) is the median, and the third quartile (Q3) is the median of the upper half.

Front

What is the lower quartile (Q1)?

Back

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

Front

What is the upper quartile (Q3)?

Back

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