Exploring Adding and Subtracting Rational Expressions

What is the purpose of a box and whisker plot?

• To compare the means of two data sets

• To show the frequency of data points

• To display data on a number line using a five-number summary

• To calculate the mean of a data set

How many sections does a box and whisker plot divide the data into?

• Three

• Four

• Five

• Six

What does the median represent in a box and whisker plot?

• The highest value in the data set

• The lowest value in the data set

• The middle value of the data set

• The average value of the data set

What does the upper quartile represent in a box and whisker plot?

• The maximum value of the data set

• The median of the upper half of the data

• The median of the lower half of the data

• The median of the entire data set

In a box and whisker plot, what does a dot typically represent?

• The quartiles

• The mean

• The median

• The maximum and minimum values

What does the range of a data set tell you?

• The difference between the upper and lower quartiles

• The total number of data points

• The difference between the maximum and minimum values

• The average value of the data set

How is the interquartile range (IQR) calculated?

• Upper quartile minus lower quartile

• Maximum value minus minimum value

• Median of the upper half minus median of the lower half

• Sum of all data points divided by the number of data points

Which part of the box and whisker plot represents the interquartile range?

• The length of the whiskers

• The space between the quartiles

• The entire length of the plot

• The length of the box

What does a longer left whisker indicate in a box and whisker plot?

• The median is to the right of the center

• The median is to the left of the center

• The data is skewed left

• The data is skewed right

What does a symmetric box and whisker plot indicate about the data?

• The data is evenly distributed

• The median is not in the center

• The data is skewed to the left

• The data is skewed to the right
