Collecting and Organising Data

Data = information. Steps to organise: 1. Collect (survey: ask everyone in class their favourite subject). 2. Tally (make tally marks as each person answers). 3. Count (count tallies for each category). 4. Display (graph). Tally marks: |||| = 5 (four vertical, one diagonal). Counting in 5s makes tallying faster. Your tally table is the data table.
