Interpreting and Comparing Histograms

What happens to the mean and median in a symmetrical histogram?

• They become identical

• They move further apart

• Only the mean is affected

• Only the median is affected

In a left-skewed graph, how do the mean and median compare to the mode?

• There is no relationship

• Mean is greater than median, which is greater than the mode

• Mean and median are greater than the mode

• Mean and median are less than the mode
