What is a Box and Whisker Plot?

Back

A Box and Whisker Plot is a graphical representation of a data set that shows its minimum, first quartile (Q1), median, third quartile (Q3), and maximum values.

Front

What does the minimum value represent in a Box and Whisker Plot?

Back

The minimum value is the smallest data point in the data set.

Front

What is the median in a Box and Whisker Plot?

Back

The median is the middle value of the data set when it is ordered from least to greatest.

Front

What are quartiles in a Box and Whisker Plot?

Back

Quartiles are values that divide the data set into four equal parts: Q1 (first quartile), Q2 (median), and Q3 (third quartile).

Front

How do you find the first quartile (Q1)?

Back

Q1 is the median of the lower half of the data set (excluding the overall median if the number of data points is odd).

Front

How do you find the third quartile (Q3)?

Back

Q3 is the median of the upper half of the data set (excluding the overall median if the number of data points is odd).

Front

What does the upper quartile (Q3) represent?

Back

Q3 represents the value below which 75% of the data points fall.

Front

What does point C represent in a Box and Whisker Plot?

Back

Point C represents the median of the data set.

Front

How do you calculate the range of a data set?

Back

The range is calculated by subtracting the minimum value from the maximum value.

Front

What is the purpose of a Box and Whisker Plot?

Back

The purpose of a Box and Whisker Plot is to visually summarize the distribution of a data set and identify its central tendency and variability.
