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 values.

Front

What does the interquartile range (IQR) represent?

Back

The interquartile range (IQR) represents the range of the middle 50% of the data, calculated as Q3 - Q1.

Front

How do you find the median in a box plot?

Back

The median is the middle value of the dataset when it is ordered from least to greatest, represented by the line inside the box of the box plot.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset, represented by the leftmost point on the box plot.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset, represented by the rightmost point on the box plot.

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, indicating that 25% of the data falls below this value.

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, indicating that 75% of the data falls below this value.

Front

How do you calculate the interquartile range (IQR)?

Back

IQR is calculated by subtracting Q1 from Q3: IQR = Q3 - Q1.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is 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 in a box plot indicates greater variability in the middle 50% of the data.
