Sara collected the femur length, in inches, of her classmates. She used these values to create a dot plot. Sara multiplied each value by 3 and created a second dot plot. Which characteristic of the two dot plots must be the same for both data sets?
The range of the data.
The mean of the data.
The interquartile range of the data.
The number of data points plotted.
Is it possible to find the mode from a box and whisker plot?
Yes, because the plot shows the frequency of each score.
No, because the plot only shows the minimum, quartiles, median, and maximum values, not the frequency of individual data points.
Yes, because the mode is always the median in a box and whisker plot.
No, because the plot only shows the mean and range.
Is it possible to find the median from a box and whisker plot? If so, what is the median value shown in the plot?
No, it is not possible to find the median from a box and whisker plot.
Yes, it is possible, and the median is 82.
Yes, it is possible, and the median is 75.
Yes, it is possible, and the median is 90.
Which measure of central tendency should be used to BEST describe the test data?
The mean because the data contains an outlier.
The median because the data contains an outlier.
The mean because the data does not contain an outlier.
The median because the data does not contain an outlier.

Which is TRUE about these two data sets?
The modes are equal.
The ranges are equal.
The Bears have a greater mean.
The Wolves have a greater median.
What effect does the outlier have on the mean temperature of Karen’s car?
Since the outlier is a low value, its removal would raise the mean.
Since the outlier is a low value, its removal would lower the mean.
Since the outlier is a high value, its removal would raise the mean.
Since the outlier is a high value, its removal would lower the mean.

Both teams performed similarly in the 21 wins based on the mean score.
Both teams performed similarly in the 21 wins based on the median score.
Team B had a closer margin of victory based on the mean absolute deviation.
Team B had a greater spread in the margin of victory based on a lower range.
Team A had a greater spread in the margin of victory based on a greater interquartile range.
What is the shape of the data?

A basketball team has these margins of victory in the first 14 games: 1, 4, 8, 15, 17, 20, 12, 13, 14, 3, 8, 3, 10, 12. The results are shown incorrectly on the box plot. What error was made in the box plot?
The error is the location of the box. The box is required to start at the minimum value of 1 and the maximum value of 20.
The median for the box plot is incorrect. The mean of the data set is 10 points, which is shown in the box plot. The median is 11 points for the set of data.
The error is the location of the whiskers. The whiskers are required to stop at the value before the minimum, which is 3, and the value before the maximum, which is 17.
The median for the box plot is incorrect. The mean of the data set is 10 points, which is shown in the box plot. The median is 12.5 points because this is the middle number in the list.
Which measure of center and spread is used to compare two sets of data that each contain an outlier that is skewing the graph?
mean and interquartile range
median and interquartile range
mean and mean absolute deviation
median and mean absolute deviation
A survey was given to two groups of students about the number of pets in their place of residence.

Group B: 0, 0, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 4
Which conclusion BEST represents the comparison between the two data sets?
The median is 1 greater for group A when comparing the two data sets. This description is a more accurate description because each set of data is uniform.
The median is 1 greater for group A when comparing the two data sets. This description is a more accurate description because each set of data is symmetrical.
The mean and median are 1 greater for group A when comparing the two data sets. This description is a more accurate description because each set of data is uniform.
The mean and median are 1 greater for group A when comparing the two data sets. This description is a more accurate description because each set of data is symmetrical.
