Collecting and recording data - Two-way tables
You can use a two way table to show two sets of information.
Investigation example
Aled carried out a survey to see how many of his classmates are left-handed. His results are shown in the table below:
| Left-handed | Right-handed | |
|---|---|---|
| Boys | 2 | 14 |
| Girls | 1 | 12 |
This is an example of a two-way table and it is used to show two different features in a survey.
In this case it shows:
- Boys and girls
- Left-handed or right-handed
You can find out lots of information from this table. For example, you can see that there are 2 left-handed boys in the class. You can also see that there are 13 girls in the class (1 left-handed and 12 not left-handed)
Question
Q1. How many right-handed children are there in the class?
Q2. How many children are there in total?
