Q. 1.1 - The Practice of Statistics for AP

Question

Based only on the stemplot, would you expect the mean travel time to be less than, about the same as, or larger than the median? Why? 

Step-by-Step Solution

Answer

The Travel Time is to be Larger then median

Step 1: Given Information

As per the given distribution data, the graph has stated to be on the right side so it is skewed towards the right hand side.

Step 2: Findings from discusion

Thus it can be expected that  the mean of the data is to be larger than the value of median. 

Mean and median of a approximately symmetric distribution which are close together. In this context distribution is exact symmetric the mean. However, the median are exact same as well .

But in this case of skewed distribution, mean is generally farther out in long tail than the median.
