Exam 13: Big Data Basics: Describing Samples and Populations

The average deviation score is frequently used in marketing research studies.

The central limit theorem states that, as sample size increases, the distribution of sample means of samples of size n (when randomly selected)approaches a normal distribution.

All of the following are characteristics of the standardized normal distribution EXCEPT that it ____.

A frequency distribution of a sample is called a(n)____________________.

A frequency distribution of a sample is called a sample distribution.

One of the most common probability distributions in statistics is the _____ distribution.

Nonresponse bias causes problems because it means that the sampling units that participated are different from those that did not participate.

The standard deviation of the sampling distribution is called the ____________________ of the mean.

Auxiliary variables are those that the researcher should build into a survey that allow a comparison between sample units that do respond and those that do not respond.

List the characteristics of the standardized normal distribution and explain why it is a useful distribution in inferential statistics.

A frequency distribution of the population elements is called a ____.

Explain the central-limit theorem and discuss why it is useful to marketing researchers.

A theoretical probability distribution of sample means for all possible samples of a certain size drawn from a particular population is called the ____.
