- 中国大学MOOC: Analysis of variance uses the ( ) test
- Analysis of variance (ANOVA) models test hypotheses about the population variance.
- Analysis<br/>of Variance is a test for equality of () A: Variances. B: Means. C: Proportions. D: only<br/>two parameters. E: distributions.
- Analysis of Variance (ANOVA) is a test for the difference in . A: means of two or more samples B: means of three or more samples C: vairance of three or more smaples D: means of two or more populations E: variance of two or more populations
- In a test of the mean of a population, if the population variance is: A: known, a z- distributed test statistic is appropriate. B: known, a t- distributed test statistic is appropriate. C: unknown, a z -distributed test statistic is appropriate.
