  1. 1What is a population?
    1. AA subset of a large group of people
    2. BA large group of observations (people, objects etc.) about which a researcher wants to draw conclusions
    3. CThe number of people in a country
    4. DThe number of people that comprise a demographic
  2. 2What does descriptive statistics do?
    1. AMake leaps and conclusions about a population from sample data
    2. BDescribe the data in a meaningful way
    3. CExplain formulae, the theory behind the statistics
    4. DCompress and condense raw data in the world into a workable size
  3. 3What is σ²M
    1. AStandard variance of the population
    2. BStandard error of the mean
    3. CStandard deviation
    4. DVariance of sample
  4. 4What are inferential statistics
    1. AA tool to predict the sample based on population data
    2. BA tool to draw inferences about a population from sample data
    3. CA way to compress and consolidate sample data
    4. DA way to estimate and make decisions about sample statistics
  5. 5What are the two inferential procedures
    1. AHypothesis testing and extrapolating
    2. BEstimation and interpolating
    3. CEstimation and hypothesis testing
    4. DHypothesis testing and determining limitations
  6. 6What is a confidence interval?
    1. AHow likely a particular value or set of values is in the given data
    2. BAn estimation of the confidence results are significant
    3. CAn estimation of the area that encompasses a particular value
    4. DA tool to define a prediction, i.e. is it true or not
  7. 7What is hypothesis testing?
    1. AHow likely a particular value or set of values is in the given data
    2. BA way to test if the hypothesis can be applied to the entire population
    3. CA way to test if the hypothesis is valid
    4. DA tool to define a prediction regarding a statement about the population parameter, i.e. is it true or not
  8. 8What is the sampling distribution?
    1. AA 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
    2. BA 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
    3. CA 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
  9. 9The standard error of the mean only refers to the [blank_start]experiment[blank_end] [blank_start]that you are doing now[blank_end], i.e. the behaviour of the averages collected [blank_start]in the experiment[blank_end], while the variance is the noise in the [blank_start]population[blank_end].
