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 maximum value in a box plot?

Back

The maximum value is the highest point on the box plot, representing the largest data point in the dataset.

Front

What is the minimum value in a box plot?

Back

The minimum value is the lowest point on the box plot, representing the smallest data point in the dataset.

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), indicating the range of the middle 50% of the data.

Front

How do you calculate the IQR?

Back

IQR = Q3 - Q1.

Front

What does Q1 represent in a box plot?

Back

Q1, or the first quartile, represents the median of the lower half of the dataset, marking the 25th percentile.

Front

What does Q3 represent in a box plot?

Back

Q3, or the third quartile, represents the median of the upper half of the dataset, marking the 75th percentile.

Front

What is the purpose of a box plot?

Back

A box plot is used to visually summarize the distribution of a dataset, highlighting its central tendency and variability.

Front

What does a longer box in a box plot indicate?

Back

A longer box indicates greater variability in the middle 50% of the data.
