Module 6
In using an ANOVA test two areas need to be considered—a random-effects model and a fixed-effects model.
In this module’s discussion, identify the difference(s) between the two models and the pros and cons of using each model in calculation.
Homework Answers
Fixed Model is used when treatment levels are fixed i.e specifically selected for the experiment. hence conclusions of ANOVA is applicable only to the selected levels not others.In other words findings from ANOVA can't be extended to cover other levels(not part of experiment for which ANVA is done) even if available in practice.
Random Model is used when treatment levels are used are kind of random sample from a large population of treaments. Hence result of ANOVA can be extended to other levels even if they are not explicitly considered as part of ANOVA.
If we look the model equation of Treatment effects Model
yij = mu (Overall mean) + Taoi (parameter representing effect of treatment) + epsillonij(random error)
Taoi is fixed for fixed effects model where as for random effects model its a random variable , and we try to estimate the variablity of this parameter.
In studies like Measurement Systems Analysis these error components are estimated and acted if significant.

PLease answer the questions given, I dont need just the conclusion of anova test Three brands of gasoline (Shell, BP, and Marathon) were deliberately selected for an observational study. The study was conducted to understand which brand of gasoline among the three selected is cheaper across the metropolitan areas of mid-west. A gas station for each brand of gas from 10 metropolitan areas were randomly selected for the study. It is a well-known fact that, the price drivers pay for...

When only two treatments are involved, ANOVA and the Student's t test (Chapter 11) result in the same conclusions. Also, for computed test statistics, t F. To demonstrate this relationship, use the following example. Fourteen randomly selected students enrolled in a history course were divided into two groups, one consisting of 6 students who took the course in the normal lecture format. The other group of 8 students took the course as a distance course format. At the end of...

Two teaching methods and their effects on science test scores are being reviewed. A random sample of 9 students, taught in traditional lab sessions, had a mean test score of 83.4 with a standard deviation of 5.1. A random sample of 7 students, taught using interactive simulation software, had a mean test score of 87.6 with a standard deviation of 6.4. Do these results support the claim that the mean science test score is lower for students taught in traditional...

Many factors will influence the distance a paper airplane will fly. Weight and shape are two factors. Through this project we will attempt to determine the optimal shape and weight for distance. We will also compare regression and ANOVA to better understand key differences between the methods. In your data, you have four groups and the groups will probably have different means. We will use ANOVA and regression to test whether these differences are statistically significant. The ANOVA model for...

6) When ANOVA F-test suggests that the population means differ, we can examine confidence intervals estimating each population mean to try to determine which population means account for the difference. These are the same one-sample T- intervals we learned in Unit 9. The fictitious data from Study #2 give these 95% confidence intervals. Which population means appear to differ? Which might be the same? Table of confidence interval calculation 1 Grade Sample Mean Std. Err. DF L. Limit U. Limit...
