a) Does high zero-order correlations between two variables result in lower standard error estimate or not? b) Is the Scheffe' method the only test that cannot be used for orthogonal contrast or not? c) In a one-way analysis of variance, sum of squares may be derived from what source?
Homework Answers
A. Since se is inversely proportional to 1-r*r, higher r makes se higher. The answer is no.
B. Scheffe method can be used for both orthogonal and non orthogonal contrasts. The answer is no.
C.In a one way data, there are two sources of variation between factor and within factor( error). Sum of squares are calculated for these two sources in the analysis of one way anova.
For further query, comment.

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...
