Sometimes, we have some data we want to investigate and putting it in a table or list can help us make sense of it. Maybe we want to see which ice cream sold the most, which pet is most popular etc. We can create a table showing the results of looking at our data. Let's see how by watching a video.
Data can be shown as:
- a list - our data is written out, usually in words
- a table - where we list each 'type' and a total for each type
- a bar graph - where columns show 'how many' of each type
