Let's determine if we are to trust using the sample as a representative of the whole population if sample bias exist.
Sample bias can be defined as a method used to obtain the sample from a population when the researcher favours one part of the population over another.
If the results of the sample are not said to be a representation of the whole population, then sample bias exists.
Since the results of the sample cannot be a true representation when sample bias exists, then we CANNOT easily trust using the sample as representative of the whole population.
