Description
This video looks at how we can group data and show it. It looks at the ideas of histograms and how we can create them and read from them. It looks at the difference between a histogram and bar chart. There is a look at why we might want to write numbers in intervals and the best way to choose those intervals. It also takes a look at how we create a percentage frequency histogram. There is way too much fun happening in this video!
