Answer:
It must be large
Random
Explanation:
For a sample to represent a population accurately, it must be large and contain random sample spaces.
A population is a group of organism of the same species living in a particular place where they can reproduce.
- A sample must be representative of a given population
- By so doing, sampling space must be large so as to properly represent the species there in.
- The sampling must be done without any bias i.e. it must be randomly carried out.
