Line Plots<br />

Date<br />

A line plot is another way to organize data. Line plots are a lot like tally<br />

charts. In line plots, you use Xs above a number line instead of tally<br />

marks next to a category. Line plots are used when you want to chart<br />

how often a certain number occurs in your data.<br />
