Nonparametric tests such as spearmans Rho make no assumptions about normality? true or false?
Nonparametric tests such as spearmans Rho make no assumptions about normality? true or false?
There is a nonparametric test for most situations where the assumptions underlining parametric tests cannot be met. Group of answer choices True False
When considerable violations of parametric assumptions occurs, we should not use nonparametric tests [Choose the ONE best answer): A. True B. False C. Undefined D. Can't tell need more information
Which of the following is NOT an assumption about nonparametric tests? a.They do not involve the estimation of population parameters. b.The expected frequencies are based on the row and column frequencies for a sample rather than on assumptions regarding how frequencies for the two variables are distributed in the population c. Data from a sample is being used to estimate the population parameter. d.They do not require variables to be normally distributed.
ess OY Parametric methods require mere restrictive assumptions about the level of data measurement and assumptions about the form of the probability distribution of the population. more fewer Determine whether the following statements are true or false. False Statement If a statistical method can be used with ordinal data, it is most likely a nonparametric method. Most parametric statistical methods require the use of ordinal data. One consideration in deciding whether to use parametric or nonparametric methods is whether O...
The Greek letter rho represents the sample estimate of the correlation coefficient. True False
(Answer True or False) One of the consequences of the non-normality of the errors is that the estimates become biased in the regression equation.
1. Explain whether the following statement is true, false, or uncertain. Be explicit about your assumptions. Support your answer by a graph. "If a person is a lender and the interest rate rises, he or she will remain a
Question 18 2 pts The Wilcoxon Rank Sum Test is a nonparametric test that can be used to compare two independent samples when the assumptions for a t-test are invalid. True O False
We calculate a parameter to make inferences about a statistic. True or False
True or False? “OR” means that only one of the logical tests must be true in order for the statement to return a value of TRUE. True False
