We are data detectives: Statistics is about collecting data and gathering all of the information that you need. There needs to be a purpose for your data collection. We gather data for a particular need. For example, we might do an investigation about our favourite colours if we were going to buy each person a t-shirt or make them a card. You can use open or closed questions to gather data. You can present your data in a graph. For example: Tally chart Scatter plot Line graph Stem and leaf graph Bar graph Pictograph A bar graph has: A title Bars (even widths) An x and y axis The y axis has numbers on it that are evenly spaced Labels on the x and y axis Once we have presented the data - we can make statistical statements by analysing it.
