  Parameters
• The standard deviation of the sampling distribution is also known as the_____

  Standard error of the mean
• A sampling method in which all the members of a group or population have an equal chance of being selected.

  Random Sampling
• A descriptive measure computed from a sample.

  Statistics
• What do you call the difference between the sample mean and the population mean?

  Sampling Error
• In this theorem, good estimate of the population mean is best achieved if sample size is sufficiently large.

  Inferential Statistics
• Subsets of a population are called

  Sample
• What do you call a single value that may refer to a parameter value?

  Point Estimate
• Refers to the range of values that contains the parameter value

  Confidence Interval
• Refers to the probability that a parameter is contained in a range of values

  Confidence Level/Interval
• Which of the following illustrates confidence level?

• Which of the following shows graphical results in making inferences about population values?

  Sampling Distribution
• When the estimate of a population parameter is equal to the estimate from a large sample, then the sample statistic is
