- Environmental differences - e.g. Nutrition
5
Q
How could you sample a population?
A
- large sample size
- selected at random

Q
What is a large sample size good to for sampling a population?
A
- As the data is representative of the whole population
- We can then use a statistical test

A
- To avoid bias
8
