How can a line plot help me organize data?

You can pick out the mode or modes of a set of data by looking at the Xs and seeing which column or columns are the highest. You can see approximately where the middle of the data—the median—is by looking at the Xs. If you count the number of Xs and divide by 2 to find the middle one, then you can easily locate the median. For example, if there are 11 values, the middle value would be the sixth one. Another way to find the median is to count in from each end and meet at the median, or middle number. • When do I want to know the mode? The median? The mean?

For example, a shoe store manager keeps track of sizes sold and based on this data, orders more shoes. Perhaps a mode is size 8. If so, the man
