Sample points are chosen using random numbers to reduce bias.
Samples are taken at regular intervals, not randomly.
The variable that is changed deliberately in an experiment.
The variable that is measured or observed in response to changes.
It may lead to biased results due to existing patterns.
Represent the whole population and be unbiased.
It is the cause of change that the scientist manipulates.
It depends on the changes made to the independent variable.
