Mike is a biologist studying mice and has access to 600 mice that live in an enclosure.
Mike wants to sample some of the mice for a study into their response to a new drug.
He decides to sample 10 mice, selecting those nearest to the enclosure's entrance.
State the population in this situation.
The population is the 600 mice living in the enclosure
State two possible issues with the sample method Mike intends using.
The sample size is very small - just 10 mice
The mice are not being selected at random - those nearest the entrance have a greater chance of being selected
Suggest one way in which Mike could improve the reliability of the results from his sample.
Mike should increase the sample size to increase the reliability of the results
