- An<br/>F test for an analysis of variance (ANOVA) tells us () A: which<br/>of the pairs of treatment groups have means that are significantly<br/>different. B: whether<br/>the variances across the treatment groups are significantly<br/>different. C: whether<br/>there is evidence that at least two of the means across treatment<br/>groups are significantly different. D: whether<br/>the experiment was randomized.
- 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
- The term ‘variance’ of the method ‘Analysis of Variance’ means: . A: The method is to compare the difference of population variances B: The method is to compare the difference of sample variances C: The method requires that variances of different groups should be equal D: The method calculates MS and compares MS, while MS is variance in concept E: The method calculates SS and compares SS, while SS is variance in concept
- Rate variances are the same as ________ variances. Efficiency variances are the same as ________ variances.
- When the sample sizes are equal, the pooled variance of the two groups is the average of the two sample variances.
