1What is a population?
- AA subset of a large group of people
- BA large group of observations (people, objects etc.) about which a researcher wants to draw conclusions
- CThe number of people in a country
- DThe number of people that comprise a demographic
2What does descriptive statistics do?
- AMake leaps and conclusions about a population from sample data
- BDescribe the data in a meaningful way
- CExplain formulae, the theory behind the statistics
- DCompress and condense raw data in the world into a workable size
3What is σ²M
- AStandard variance of the population
- BStandard error of the mean
- CStandard deviation
- DVariance of sample
4What are inferential statistics
- AA tool to predict the sample based on population data
- BA tool to draw inferences about a population from sample data
- CA way to compress and consolidate sample data
- DA way to estimate and make decisions about sample statistics
5What are the two inferential procedures
- AHypothesis testing and extrapolating
- BEstimation and interpolating
- CEstimation and hypothesis testing
- DHypothesis testing and determining limitations
6What is a confidence interval?
- AHow likely a particular value or set of values is in the given data
- BAn estimation of the confidence results are significant
- CAn estimation of the area that encompasses a particular value
- DA tool to define a prediction, i.e. is it true or not
7What is hypothesis testing?
- AHow likely a particular value or set of values is in the given data
- BA way to test if the hypothesis can be applied to the entire population
- CA way to test if the hypothesis is valid
- DA tool to define a prediction regarding a statement about the population parameter, i.e. is it true or not
8What is the sampling distribution?
- 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
- 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
- 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
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].
- Aexperiment
- Bpopulation
- Csample
- Dthat you are doing now
- Eparameter
- Fstatistic
- Gthat you did previously
- Hin the experiment
- Ifor the population
- Jin a previous experiment
- Kpopulations
- Lexperiments
- Msamples
- Nsampling distributions
10M is the unbiased estimate of μ
- AVerdadeiro
- BFalso
11[blank_start]Variability[blank_end] tells you how much you can trust your [blank_start]experiment[blank_end]
- AVariability
- Bexperiment
12As 'n' gets larger, you get a better estimate of the [blank_start]true population mean[blank_end].
- Atrue population mean
13Decreasing standard deviation makes the σ²M more spread out, and pulls data away from the population mean.
- AVerdadeiro
- BFalso
