In need of assistance for homework; the chapter is based on comparing the means of 3 or more independent samples: one-way analysis of variance

Thank you in advance for any aid that can be offered.

6.) In a one-way ANOVA, the following results are obtained: SSbetween = 83.7 and SStotal = 102.6. Therefore, SSwithin =

a. 186.3

b. 18.9

c. 51.3

d. none of the above

7. )The following are the scores from two groups of two cases each:

- Group 1: 2, 4

- Group 2: 4, 6

SSwithin =

a. 6

b. 8

c. 3

d. 4

8.) The following are the scores from two groups of two cases each:

- Group 1: 2, 4

- Group 2: 4, 6

SStotal =

a. 4

b. 3

c. 8

d. 6

9.) If SStotal = 400 and SSbetween = 250, then SSwithin is

a. k - 1

b. 150

c. n - k

d. 650

10.) A one-way ANOVA has been performed and a significant F obtained. At this point we may wish to continue the statistical analysis using a

a. modified between-groups estimate

b. HSD test

c. t test for independent means

d. factorial design

Solution

6)  SSbetween = 83.7 and SStotal = 102.6. Therefore,

SSwithin =SS total - SS between = 102.6-83.7 =18.9

7)

From Excel

SSwithin =4

8)

SStotal = 8

9)

If SStotal = 400 and SSbetween = 250, then

SSwithin= SS total - SS between =400-250=150

10)

A one-way ANOVA has been performed and a significant F obtained. At this point we may wish to continue the statistical analysis using a HSD test.

Tukey\'s range test, also known as the Tukey\'s test, Tukey method, Tukey\'s honest significance test, Tukey\'s HSD (honest significant difference) test, or the Tukey–Kramer method, is a single-step multiple comparison procedure and statistical test.It can be used on raw data or in conjunction with an ANOVA (Post-hoc analysis) to find means that are significantly different from each other
