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.
Homework Answers
We know that,
A one-way ANOVA only involves one factor or independent variable, whereas there are two independent variables in a two-way ANOVA.
Hence,
Third statement is false about one way ANOVA.

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...

Select the false statement about ANOVA. A one-way ANOVA hypothesis test considers comparisons between populations based on one characteristic, while a two-way ANOVA hypothesis test considers comparisons between populations based on multiple characteristics. If a researcher wants to study the effectiveness of three brands of nicotine patches, the researcher should use a One-Way ANOVA test. If a researcher wants to compare the mean wages of females in different age groups at a particular company, he or she should not use...

One-Way ANOVA and Randomized Black Experiment (Two-Way
ANOVA)
An automotive engineer wanted to determine whether the octane of gasoline used in a car increases gas mileage. He selected six different brands of car and assigned a driver to each car. Then 5 gallons of the gasoline selected was placed in the car. The car was driven around a closed track at 40 miles per hour until it ran out of gas. The number of miles driven was recorded and then...

What is the purpose of post tests for a significant one-way ANOVA? a.)to increase the experiment-wise alpha high enough to prevent a Type II error. b.)to determine whether a Type I error was committed. c.)to determine how much difference exists between the treatments. d.)to determine which treatments are significantly different from the others.

Question: 1 Part A: There are several assumptions that are made in the one-way ANOVA model. Which one in the list is NOT one of the assumptions? a. The populations means are all equal if Ho is true. b. The variances within each treatment group are statistically equal. c. 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...

Answer True or False to the following: - If we were comparing the time it takes for a headache to subside to a certain level for six different dosages of the same medication using a one-way ANOVA procedure, then this problem has six levels and one factor. - In a one-way ANOVA, the entity on which a response variable is measured is called the level unit. - One assumption for the one-way ANOVA procedure is that the samples are independent...
