1-Variable Statistics: Target 1A

Which car club has the higher median?

• Cruisers

• Car Hops

• Their medians are the same

• You can not tell from the box plots

The median is the...

• average of all data values

• the most frequently occurring number

• the difference between the biggest and smallest value

• the middle value

A measure of variability helps determine the center of the data.

• True

• False

Which data set shows a greater spread (larger IQR)?

• Chess Club

• Checkers Club

• They have the same spread.

• You cannot tell from the box plots.

Here are the times (in minutes) that six students needed to finish a quiz:

10, 14, 15, 15, 14, 10

The standard deviation for this data is 2.

A seventh student took 8 minutes to finish the quiz. We added his time to our data. What will happen to the standard deviation?

• It will decrease because our range is bigger.

• It will increase because our range is bigger.

• It will not change.

• It will decrease because we have more numbers in our data set.

A distribution whose dot plot or histogram takes the form of a bell with most of the data clustered near the center and fewer points farther from the center

• Bell-Shaped Distribution

• Bimodal Distribution

• Skewed Distribution

• Uniform Distribution

A distribution where one side of the distribution has more values farther from the bulk of the data than the other side, so that the mean is not equal to the median

• Bell-Shaped Distribution

• Skewed Distribution

• Uniform Distribution

• Bimodal Distribution

Which statement correctly describes the shapes of the dot plots for cars and SUVs?

• SUVs: symmetrical
  Cars: skewed left
• Both are skewed left
• Both are symmetrical
• SUVs: skewed right
  Cars: Skewed left

Which of the following best describes the shape of the distribution?

• SKEWED LEFT
• SKEWED RIGHT
• UNIFORM
• SYMMETRICAL

The given distribution is skewed left. Compare the median and the mean.

• The median and the mean are the same because they both are measures of center

• The median is less than the mean since the distribution is skewed left.

• The median is greater than the mean since the distribution is skewed left.

• There is not enough information to compare the median and the mean.
