  • A subset of a large group of people

  • The number of people that comprise a demographic

  • The number of people in a country

What does descriptive statistics do?

Select one of the following:

  • Compress and condense raw data in the world into a workable size

  • Explain formulae, the theory behind the statistics

  • Describe the data in a meaningful way

  • Make leaps and conclusions about a population from sample data

Explanation

What is σ²M

Select one of the following:

  • Standard error of the mean

  • Standard deviation

  • Standard variance of the population

  • Variance of sample

Explanation

Question 4 of 13 Question 4 of 13

1

What are inferential statistics

Select one of the following:

  • A tool to predict the sample based on population data

  • A tool to draw inferences about a population from sample data

  • A way to compress and consolidate sample data

  • A way to estimate and make decisions about sample statistics

Explanation

Question 5 of 13 Question 5 of 13

1

What are the two inferential procedures

Select one of the following:

  • Estimation and hypothesis testing

  • Estimation and interpolating

Explanation

Question 6 of 13 Question 6 of 13

1

What is a confidence interval?

Select one of the following:

  • An estimation of the confidence results are significant

  • A tool to define a prediction, i.e. is it true or not

  • How likely a particular value or set of values is in the given data

  • An estimation of the area that encompasses a particular value

Explanation

Question 7 of 13 Question 7 of 13

1

What is hypothesis testing?

Select one of the following:

  • A way to test if the hypothesis is valid

  • A tool to define a prediction regarding a statement about the population parameter, i.e. is it true or not

  • How likely a particular value or set of values is in the given data

  • A way to test if the hypothesis can be applied to the entire population

Explanation

Question 8 of 13 Question 8 of 13

1

What is the sampling distribution?

Select one of the following:

  • A hypothetical distribution of values of a particular sample statistic made by repeatedly sampling "n" times from a population and calculating the value of the population parameter for each sample

  • A hypothetical distribution of values of a particular sample statistic made by repeatedly sampling "n" times from a population and calculating the value of the statistic for each sample

  • A hypothetical distribution of values of a particular population parameter made by repeatedly sampling "n" times from a sample and calculating the value of the statistic for each sample
