a) nonparametric Mann-Whitney U
b) time series
c) t tests_________________________________________________________________________
Statistical Tools Review Questions
Information from the autocorrelation program should be available before running which analysis?a) nonparametric (Mann-Whitney U)
b) parametric (t test and ANVOA)
c) both a and b are correct_________________________________________________________________________
Statistical Tools Review QuestionsInformation about serial dependency (evident trend) within a single variable is provided by
a) autocorrelation
b) time series
c) both a and b are correct_________________________________________________________________________
Statistical Tools Review QuestionsData from several studies can be accumulated and analyzed with
a) binomial expansion
b) Bayesian Analysis
c) both a and b are correct_________________________________________________________________________
Statistical Tools Review Questions
You are correct; the time series analysis is the most flexible of these three choices.The "real" best tool is, of course, determined by the nature of your research design.

Statistical Tools Review Questions
No, time series is the most flexible of the these three programs.But, the "real" best tool is, of course, determined by the nature of your research design.

Statistical Tools Review Questions
You are correct. Autocorrelation should be completed before running the t test ANOVA, or the Mann-Whitney U.If the autocorrelation is significant, there is risk that t test or ANOVA will overestimate the extent of difference between the variables.

Statistical Tools Review Questions
Although your answer is correct, the best answer is "c". Autocorrelation should be completed before running the t test, ANOVA, or the Mann-Whitney U.If the autocorrelation is significant, there is risk that t test or ANOVA will overestimate the extent of difference between the variables.

Statistical Tools Review Questions
Correct. Both the time series (C statistic) and autocorrelation programs assess serial dependency.The autocorrelation only calculates the dependency within a variable. The time series calculates the dependency within a variable and the impact when variables are added together.

For this question the best answer is also "c". Both the time series (C statistic) and autocorrelation programs assess serial dependency.The autocorrelation only calculates the dependency within a variable. The time series calculates the dependency within a variable and the impact when variables are added together.
