<h3>What is a stemplot?</h3>
A stemplot is a graphical way of displaying numerical data that uses place value to group the data. The leftmost digits of the data values form the stem, and the rightmost digits form the leaf.
The distribution is symmetric, because the left and right halves of the stemplot are roughly mirror images of each other. The mean and median are both about $25, because the middle value of the data is $25, and the sum of the data values divided by the number of data values is also $25. The distribution is not skewed to the right or left, because there are no long tails or outliers on either side of the peak.
