First you want to gather all your data and put it in order even if there is a number more than once. This way you a have a nice organized line of numbers to take from. Next, You want to make a horizontal line for the base of the plot and you also want to name your line plot, For example,"What is the average hight of fifth graders?". After that you need to need to put your numbers in order from least to greatest under the line plot. Last but not least, You need to put the "X's" on top of the number for how many people are that hight.
