Shape Center Spread of Data

• both sets of data have the same median
• Ander's center is at 6
• Marcus's center is at 7
• Ander's spread is greater than Marcus's

• the shapes of both plots are symmetrical
• the data spreads for both populations are the same
• Route 9 is skewed left
• Route 9 is skewed right

Describing the shape of a data set that is a mirror image one both sides of the center point.

• symmetrical

• unimodal

• skewed

• uniform

Describe the histogram:

• Left Skewed

• Symmetrical

• Right Skewed

• Uniform

• Mode
• Median
• Mean
• IQR

One of three statistics that represents the spread of a set of data: including range, and interquartile range.

• measure of center

• interquartile range

• measure of variability

• box and whisker plot

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

• skewed left

• skewed right

• uniform

• symmetrical

Should we use the mean or the median to represent the center of the data?

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

• center: median

  spread: standard deviation

• center: mean

  spread: IQR

• center: mean

  spread: standard deviation

• center: median

  spread: IQR
