carry out our research?
a) All individuals aged 18 and over in a population

labour market

b) Non-scientific: individuals’ preferences for dogs or cats can be measured; however, we cannot
have an objective measure of which animal is best.
c) Scientific: we can measure the level of satisfaction of the same people watching a film with and
without popcorn and find out whether there are differences in their level of enjoyment.
4. When do we need to draw a random sample?
a) When we have information from all entities of interest
