To create a dot plot, we put the numbers 1 – 10 along the x-axis. Then you take the first number in the dataset, which is a 3, and place a dot above the three:
Then you take the next number in the dataset, which is a 2 and put a dot above the 2.
The next point in the dataset is another 2, so we place a dot above the dot above the first dot.
We continue adding dots for every point in the dataset until we have all of the data points are on the graph. The completed dot plot is shown below:
Dot Plots are an excellent way to display quantitative data that has a small amount of variability. Because the higher the variability in the dataset the more spread out the data is, and therefore the shorter each of the bars is.
