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.

What does the lower quartile (Q1) represent?

Back

The lower quartile (Q1) is the value below which 25% of the data falls.

Front

What does the upper quartile (Q3) represent?

Back

The upper quartile (Q3) is the value below which 75% of the data falls.

Front

How do you find the median of a dataset?

Back

To find the median, arrange the data in ascending order and locate the middle value. If there is an even number of values, average the two middle values.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

How do you calculate the interquartile range (IQR)?

Back

The interquartile range (IQR) is calculated by subtracting the lower quartile (Q1) from the upper quartile (Q3): IQR = Q3 - Q1.

Front

What is the purpose of a box plot?

Back

A box plot visually summarizes the distribution of a dataset, highlighting its central tendency and variability.

Front

What does a box plot tell you about outliers?

Back

Outliers are data points that fall outside the range defined by Q1 - 1.5*IQR and Q3 + 1.5*IQR.

Front

How can you identify the median in a box plot?

Back

The median is represented by the line inside the box of the box plot.
