Creating Dot Plots

Dot plots are simple visual representations of small sets of data. Generally, a dot is used to represent each sample that fits into a particular category. A category can be a qualitative characteristic or it can be a quantitative value or range of values. Watch to see how to make a simple dot plot.

Creating Histograms

In this video, Khan creates a quick histogram. Be sure to recognize the fairly minute difference between a histogram and a bar graph. Both are made of bars that represent the size or frequency of that particular group. One of the key differences is that bar graphs group data by quanitative groups where histograms group data in quantitative groups.
