Sandra wants to study how students in their senior year of high school prepare for college. She starts by visiting an elite boarding school nearby. Sandra knows that to make general claims about seniors preparing for college, she will need to randomly select from the population she wants to generalize to. return to the high school next year to study the new seniors. be aware of her intentions, so the study will be valid and reliable. visit more schools so that her sample is representative of the group she wants to generalize to

- Visit more schools so that her sample is representative of the group she wants to generalize to.

Explanation:

Sandra must 'visit more and more schools in order to ensure that the sample which she selects appropriately represents the group about which she is generalizing.' In the Inferential statistics, to reach an accurate, authentic, and objective inference about the representative population, the selection of the sample must be unbiased and random. Thus, the sample must be selected from a wide area to offer equal opportunity to every part of population to represent that assists in making valid and reliable claims.
