Mean Median Mode Dotplot

The graph shows the data from an experiment. Based on the shape of the distribution, what measure of center should be used?

• Mean

• Median

• Neither

Which is the best measure of center for the graph?

• Mean and median

• Mean only

• Median only

Which is the best measure of center for the graph?

• Mean

• Mean only

• Median only

When finding the median, what do you do if there are two middle numbers?

• Add them together and divide by 2

• Write them both as the answer

• Give up

• Pick one

What is the best measure of center for this data set?

• Mean

• Median

• Neither

How are the Mean and Median related for this data set?

• Mean > Median

• Mean = Median

• Mean < Median

What would be the best measure of center for this data set?

• Skewed right so median

• Skewed left so median
