Question

Quizplus · Accepted Answer

The purpose of statistical inferences is to use sample data to make generalizations about population characteristics. Option A is incorrect because statistical inferences only provide estimates of population characteristics, not a full description. Option C is incorrect because statistical inferences do estimate mean, median, mode, variance, and skewness, but this is not their main purpose. Option D is incorrect because statistical inferences are not limited to the study of binomial or Poisson random variables.
