Box Plots

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that displays the 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

How do you find the median of a dataset?

Back

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

Front

What is the interquartile range (IQR)?

Back

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

Front

How do you calculate the IQR?

Back

IQR = Q3 - Q1.

Front

What does the maximum value in a box plot represent?

Back

The maximum value is the highest data point in the dataset.

Front

What does the minimum value in a box plot represent?

Back

The minimum value is the lowest data point in the dataset.

Front

What is quartile 1 (Q1)?

Back

Quartile 1 (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What is quartile 3 (Q3)?

Back

Quartile 3 (Q3) is the median of the upper half of the dataset, representing the 75th percentile.

Front

What does a box plot show about data distribution?

Back

A box plot shows the spread and skewness of the data, highlighting outliers and the central tendency.
