What is H0 for a one-way ANOVA? If H0 is rejected, does that imply that each mean is significantly different from every other mean?
Homework Answers
Null hypothesis for one way ANOVA is given by:
that is, mean of all k groups are equal to each other.
Hence, alternate hypothesis is that at least one of the groups has a mean that is significantly different from the other groups.It does not necessarily imply that each mean is significantly different from every other mean.

In a one-way ANOVA, what does it mean to reject the statement in the null hypothesis if three treatment groups are being compared? Choose the correct answer below. A. Rejecting the statement in the null hypothesis means that there is insufficient evidence to conclude that the mean of one of the populations is different than the other two or that all three populations are different. B. Rejecting the statement in the null hypothesis means that there is sufficient evidence to...

When 3 or more groups are included in an ANOVA, and the probability level indicates that the null hypothesis should be rejected, what does this tell the researcher? Group of answer choices That each mean is significantly different than every other one Specific post hoc analyses should be done to determine where there are group differences Which groups are different from which other groups It will be necessary to perform t-tests on each of the pairs of means to determine...
Which of the following statements about the one-way ANOVA are correct?
Which of the following statements about the one-way ANOVA are correct? (Select all that apply) The larger the variability within groups relative to the variability between groups, the larger the F test statistic tends to be. The results of the ANOVA F test does not tel us which groups are different or how different they are. An F-distribution is symmetrical about 0 and extends indefinitely in both directions In a one-way ANOVA, if the null hypothesis is rejected, we conclude that the population means...

It signifies that the ANOVA compares the means of a variable for populations that share one common population mean. OB. It signifies that the ANOVA can be performed for multiple populations, but those populations cannot be inferred by the results. OC.

Which of the statements about one-way ANOVA is FALSE?The purpose of one way ANOVA is to verify whether the data collected from different sources converge on a common mean.ANOVA deals only with one factor, such as treatment or group.It is used when there are two independent variables in the experiment.There can be any number of levels in one-way ANOVA.

The mean of the observations, in at least one treatment group, is statistically significantly different from the mean of the observations in any one of the other treatment groups. d. All...
