Comparing Box Plots

Front

What do points A and E represent on the box plot?

Back

Least and Greatest Value

Front

What is a box plot?

Back

A graphical representation of data that shows the distribution through five summary statistics: minimum, first quartile, median, third quartile, and maximum.

Front

What does the median represent in a data set?

Back

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

Front

How do you find the range of a data set?

Back

The range is found by subtracting the smallest value from the largest value in the data set.

Front

What do the first and third quartiles represent?

Back

The first quartile (Q1) is the median of the lower half of the data, and the third quartile (Q3) is the median of the upper half of the data.

Front

What does a higher median indicate about a data set?

Back

A higher median indicates that the central tendency of the data is higher, meaning that half of the values are above this point.

Front

What is the purpose of comparing box plots?

Back

Comparing box plots helps to analyze and interpret differences in distributions, medians, ranges, and quartiles between different data sets.

Front

What does it mean if two box plots have the same median?

Back

It means that the central value of both data sets is the same, but it does not indicate that the distributions are identical.

Front

What is an outlier in a box plot?

Back

An outlier is a data point that lies significantly outside the range of the other data points, often represented as a dot or asterisk on the plot.

Front

How can you tell which group has a greater range from box plots?

Back

The group with the longer box or whiskers in the box plot has a greater range.
