Answer:
Given Data
a) Calculate the Within variance , by averaging the category varinces.
= 31.77
b) By calculating the variance between the sample means.
Type | Type Mean | Type Mean - Overall Mean | ![]() |
Type 1 | 44 | 4.33 | 16.7489 |
Type 2 | 44.1 | 4.43 | 19.6249 |
Type 3 | 30.9 | -8.77 | 76.9129 |
Total | 113.2867 |
= 56.64335
c) Determine the "Between" variance , by multiplying the answer from part b.
= 4 * 56.64335
= 226.5734
d) Calculate the F - statistic by dividing the answer from part c
= 7.363451
F = 7.3635
F - statistic = 7.3635

Lab 12-Stat 212 Online Suppose we have the following scenario: Rapid drainage of floodwater is crucial to prevent damage during heavy rains. Several designs for a drainage canal were considered for a certain city. Each design was tested four times, to determine how long it took to drain the water in a reservoir. The following table presents the drainage times, in minutes. Mean S. Dev. Variance (ie. SD) n The overall average is x = 39.67 Type 1 44 4.12...
Suppose we wanted to compare the somatic complaints (as measured on a scale known as the Physical Symptom Scale or PSS) of three groups of people: non-smokers, smokers, and people who recently quit smoking. Using the following data for the PSS score, do a one-way ANOVA to evaluate smoking and PSS scores: Nonsmokers Smokers Quitters 19 31 30 28 29 22 17 22 29 20 29 29 25 28 34 ...
1. Write up the results from this
analysis using APA format. Make sure you include each group mean
(and SD) exam score, the correct F stat with the correct degrees of
freedom and p-value, decision regarding the null, and the follow-up
comparisons (if necessary). Use the example in the SPSS ANOVA
lecture to help guide you. [3 points]

2. An experiment was conducted to compare five treatments for reducing fever. Thirty-five patients were randomly assigned into five treatment groups. The patients' temperatures were taken two hours after receiving the treatment, and are given below. We will test the claim that there is no difference in mean body temperature among each of the five treatment groups using a 5% significance level. Placebo Aspirin Anacin Tylenol Bufferin 98.3 96.0 97.2 95.1 96.1 98.7 96.6 97.4 95.7 96.5 98.1 95.3 96.9...
A telemarketing firm has studied the effects of two factors on the response to its television advertisements. The first factor is the time of day at which the ad is run, while the second is the position of the ad within the hour. The data in the following table, which were obtained by using a completely randomized experimental design, give the number of calls placed to an 800 number following a sample broadcast of the advertisement. If we use Excel...

An experimenter wants to know if having a pet or friend present
while taking a stressful math test helps reduce anxiety. She
recruits 120 people to participate in the study and each person
takes a difficult math test under a strict time limit. The
participants are also randomly assigned to take the test alone,
with a friend in the room, or with a therapy dog in the room. After
taking the test, participants completed a survey that assessed how
stressful...
