Question

Maci surveyed all the members of her softball team about their favorite sport. Based on these results, Maci concludes that softball is the favorite sport among all her classmates. Explain why Maci's conclusion might not be valid. How could she change the survey to achieve a more valid conclusion?

Answer 1

Using sampling concepts, it is found that the sample is biased, hence a more valid conclusion would be reached surveying groups that involve all her classmates, for example, the same proportion out of all sports teams.

What is sampling?

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, she surveys only members of the softball team, and considering that people are likely to play their favorite sport, the sample is biased, hence a more valid conclusion would be reached surveying groups that involve all her classmates, for example, the same proportion out of all sports teams.
