When statisticians collect information to find characteristics of a large group of people, they survey part of the group. what is the part of the group called?

a.) specimen
b.) part
c.) population
d.) sample

The correct answer is D.) Sample

Explanation:

In statistics and related fields, the sample refers to the portion of the population selected for a study that is used to draw broader conclusions about all the population. This method issued when surveying all the population is too difficult or impractical. For example, if a statistician wants to know the preferences of voters for the next elections he/she cannot ask every citizen of a country instead he/she might select 1000 people (the sample) and based on the preferences of this sample predict preferences for all the population. According to this, it is  "sample" the correct term in this case.
