So you want to know everything there is to know about dot plots and column graphs - well here is the video for you. I take a look at what dot plots are, and how they can be used to find the mode of data. I move onto looking at column graphs and how they can also be used to represent data before moving on to look at how we can use numerical graphs to find things like mean, median, mode, and range.
There are some examples, and the video ends by looking at the tricks which can be used in Mathematics to try and confuse you. Not fair Barry!
