Within-group variation is reported inANOVAoutput as SS(W) or which means Sum of Squares Within groups or SSW: Sum of Squares Within. It is intrinsically linked tobetween group variation(Sum of Squares between),variancedifference caused by how groups interact with each other. SSW is one compone...
The main responsibility of a project manager is to manage individualprojectswithin a program or a portfolio to reach the project’s goals.

who will have to train or clear a steep learning curve to set one up. Once users get a handle on the tool, they’ll find a limitation harder to get used to: its lack of collaboration. It’s not as collaborative as cloud-based software and can’t be used by anyone on the team who...
To conclude that the group means are not equal, you want low within-group variance. Why? The within-group variance represents the variance that the model does not explain. Statisticians refer to this as random error. As the error increases, it becomes more likely that the observed differences...
features into 2, 3, 4, and up to 30 clusters. The clustering effectiveness is measured using the Calinski-Harabasz pseudo F-statistic, which is a ratio of between-cluster variance to within-cluster variance. In other words, a ratio reflecting within-group similarity and between-group diffe...
On the surface, Version B seems to be performing better with more leads. But to be confident that this difference is not just due to chance, you conduct a statistical test and find that the results are statistically significant. This tells you that the difference in performance between the tw...
ANOVA, orAnalysis of Variance, is an amalgamation of multiple statistical models to find the differences in means within or between groups. Multiple components of anANOVAanalysis can be used to interpret the results in Excel. The following dataset showcasesANOVAanalysis results. ...
