In a study of college search behaviors among the families of college-bound high school students, the search behaviors are very different from family to family. In the situation described, which guideline below best explains why the researcher will use a larger sample size?
A) The greater the variance within the population, the larger the sample should be.
B) The greater the proportion of incidence of the estimate, the larger the sample should be.
C) The smaller the dispersion range, the larger the sample must be.
D) The higher the level of frequency control in the estimate, the larger the sample must be.
E) The greater the number of quotas of interest within a sample, the larger the sample must be.

A) The greater the variance within the population, the larger the sample should be.

Explanation:

The variance of a sample mean is inversely proportional to the sample size, that is, the larger the sample size the smaller the variability of the sample. When sample size increases, the range decreases and hence the variance decreases resulting in a more accurate research result with minimal experimental error.

Hence the researcher should employ a large sample size to reduce the variation in the population.

- "sack of constantinople, (april 1204). the diversion of the fourth crusade from the holy land to attack, capture, and pillage the byzantine city of constantinople divided and dissipated the efforts of the christians to maintain the war against the muslims. the fourth crusade was corrupted from its purpose early on."

- "the crusades were a series of religious wars undertaken by the latin church. the first crusade arose after a call to arms in 1095 sermons by pope urban ii. the first crusade unleashed a wave of impassioned, pious catholic fury, which was of constantinople, the capital of the christian-controlled byzantine empire."
