4) An ANOVA model with 4 groups and 10 subjects in each group has a total SS equal to 400, and within SS equal to 300, The MS between and the F value are equal to?

k = 4 , N = 40

Using excel

* Correct Answer : 33.33 , 4.00

Please check because correct choice is not given

5) For an ANOVA model with 3 groups and total of 27 subjects, the critical value for rejecting the null hypothesis at the 0.05 level of significance is.

A. 99.50

B.  3.40

Answer : k = 3 , N = 27

DF Numerator = 3 - 1 = 2

DF Denominator = 27 - 3 = 24

Using Excel , at alpha = 0.05

Critical value = =FINV(0.05,2,24) = 3.40

  • B. 3.40

12 subjects in a study were randomly assigned into two equally sized groups. One group was shown a short video on how to fold paper cranes. The other group was given an instruction booklet on how to do so. They were then asked to make paper cranes for the next hour. The number of paper cranes each subject made was recorded and is listed in the table below. The researchers are interested in whether there was a difference in the...

A researcher randomly assigns 33 subjects to one of three groups. Group 1 receives technical dietary information interactively from an on-line website. Group 2 receives the same information from a nurse practitioner, while Group 3 receives the information from a video made by the same nurse practitioner. The researcher looked at three different ratings of the presentation: difficulty, usefulness, and importance to determine if there is a difference in the modes of presentation. In particular, the researcher is interested in...

A researcher randomly divides 19 subjects into two groups. One group receives a new drug called RT56 for 3 months, the other a placebo (looks like RT56, but is a sugar pill). She then measures reaction time (RT) on a complex task and finds the following RT s in seconds (s): Group 1 Group 2 RT56 Placebo N=10 N=9 .456 .532 .347 .458 .435 .768 .234 .643 .521 .678 .411 .569 .398 .486 .254 .647 .391 .501 .289
