Mean and Median vs Shape of Distribution

This is the box plot from question 7. How would you describe the skewness

• The data is symmetrical

• The data is positively skewed

• The data is negatively skewed

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

• skewed left

• skewed right

• uniform

• symmetrical

Which measure of center will be the smallest?

(Remember which one pulls toward the tail)

• median

• mean

• mode

Describe the shape of the graph.

• skewed

• symmetrical

• uniform

What is the shape of the distribution?

• symmetric

• uniform

• skewed to the right

• skewed to the left

What is the shape of the data?

• symmetrical

• skewed left

• skewed right

• uniform

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?

(a)  

Given that the data is symmetric, which pair of measures should be used to represent the data?

• center: median

  spread: standard deviation

• center: mean

  spread: IQR

• center: mean

  spread: standard deviation

• center: median

  spread: IQR

Because this distribution is ____________ to the ___________, we would use the ______________ for the center and the _____________ for the spread of the data.

• symmetric, middle, median, IQR

• skewed, left, median, IQR

• skewed, left, mean, IQR

• skewed, right, median, standard deviation
