Recording and organising data is the foundation of data handling. There are many ways to organise data to make it easier to use. Dot plots and frequency tables both display how often different values occur in a set of numerical data. Remember, like always, the names don't matter as much as the idea behind them. A dot plot is like a bar chart, but it displays data using dots (not bars). And a frequency table is like a dot plot, but it displays data in a simple table (not a fancy diagram).
