Question

surveys quick check
why are random surveys important? (1 point)
random surveys collect data from everyone in a population.
random surveys provide results with as little bias as possible.
random surveys are expensive but provide quicker results than non - random surveys.
random surveys can be facilitated very quickly.

Explanation:

Random surveys aim to select participants without any preference. This selection method helps in reducing bias. For example, if we are surveying about a school's lunch menu and we randomly pick students from different grades, genders, etc., rather than just picking from one class (which would be a biased sample). The first option is wrong as random surveys are samples, not the entire population. The third option is incorrect as random surveys aren't necessarily more expensive or quicker. The fourth option is not the key reason - the main focus is on bias reduction.

Answer:

Random surveys provide results with as little bias as possible.
