Population and samples

Down

• 2. A sample is a selection of individual members or items from the population. (4, 2, 1, 6)
• 3. A population is a collection of individual people or items. A population may be of finite size if you can count how many of them there are, or of infinite size if it is impossible to know exactly how many members there are in the population. (4, 2, 1, 10)
