Box Plots

Front

What is a box plot?

Back

A box 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 median represent in a box plot?

Back

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

Front

What are quartiles in a box plot?

Back

Quartiles are values that divide a dataset into four equal parts: Q1 (25th percentile), Q2 (50th percentile or median), and Q3 (75th percentile).

Front

How do you find the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

How do you find the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset.

Front

What does the interquartile range (IQR) represent?

Back

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

Front

What percentage of data lies between Q1 and Q3 in a box plot?

Back

50% of the data lies between Q1 and Q3.

Front

How can you determine if a dataset has outliers using a box plot?

Back

Outliers are typically represented as individual points outside the whiskers of the box plot, which extend to 1.5 times the IQR from Q1 and Q3.

Front

What does a longer whisker in a box plot indicate?

Back

A longer whisker indicates a greater spread of data points in that direction, suggesting more variability.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is to provide a visual summary of the distribution, central tendency, and variability of a dataset.
