Box Plots

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows its minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

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.

Front

How do you find the median if there are two middle numbers?

Back

Add the two numbers in the middle and then divide by two.

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of the dataset.

Front

What is the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of the dataset.

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).

Front

How do you calculate the IQR?

Back

Subtract Q1 from Q3.

Front

What does a box plot help to visualize?

Back

A box plot helps to visualize the distribution, central tendency, and variability of a dataset.

Front

What does the length of the box in a box plot represent?

Back

The length of the box represents the interquartile range (IQR), showing the range of the middle 50% of the data.

Front

What do the 'whiskers' in a box plot indicate?

Back

The 'whiskers' extend from the box to the smallest and largest values within 1.5 times the IQR from the quartiles.
