Chapter Overview
Data answers a question only when every response is counted once in the correct category.
How Many Ponytails? introduces collecting and organising data. Children ask a simple question, use tally marks, place answers in categories, and read a table or pictograph to compare groups.
Collecting Data
- Choose clear categories before recording answers.
- One tally mark records one response.
- The fifth tally crosses the first four to make a group of five.
Reading the Results
- Add tallies to find each category's frequency.
- The greatest frequency is the most common result.
- Find a difference by subtracting the smaller count from the larger count.
