Organic Chemistry (CHEM311) Fall 2005 Dr. Robert F. Dias So, how about rings? For now we will draw all rings as flat entities. That will change later, but for now, if we want to draw the ring form of hexane (C6H12), we would draw a hexagon… Remember, each kink is a carbon and the hydrogens are there, but we choose not to show them

In this case you would probably use repeated measures ANOVA (or, if the assumptions for this are not met, the non-parametric equivalent, Friedmans’s test). 3.2 Two or more groups of subjects The temptation with such data may be to compare subjects at each time point separately, perhaps with a series of unpaired t-tests. This is not appropriate.

oak.ucc.nau.edu

The multivariate analysis of variance (MANOVA) is a complex statistic similar to ANOVA but with multiple dependent variables analyzed together. That is, the MANOVA is a multivariate extension of ANOVA. The dependent variables should be related conceptually, and they should be correlated with one another at a low to moderate level.
