Estimating µ with Small Samples:
... For samples of size 30 or larger we can approximate the population standard deviation σ by s, the sample standard deviation. Then we can use the central limit theorem to find bounds on the error of estimate and confidence intervals for µ. However, there are many practical and important situations wh ...

2-way ANOVA notes File
... It can be shown that if we divide the sums of squares by the respective number of degrees of freedom we obtain the mean square errors and that these are all estimates of the (again supposed common) variance under the null hypothesis that there are no systematic effects: H0 : ...

ANOVA & Regression
... Analysis of Variance Is used when you want to compare means for three or more groups. You have a normal distribution (random sample or population). It can be used to determine causation. It contains an independent variable that is nominal and a dependent variable that is interval/ratio. ...
