The art of teaching is the art of assisting discovery.
Mark Van Doren


If you can't explain it simply, you don't understand it well enough.
Albert Einstein

Any fool can know. The point is to understand.

9. F tables: There is an F table for each alpha (right tail). The rows represent denominator degrees of freedom and the columns represent numerator degrees of freedom.
Most hypothesis testing problems avoid left tailed tests. Sometimes, however, the left F critical value is needed. If you have a calculator --like Casio fx 9750 or 9860, then go to Dist, F, InvF, enter 1-alpha or 1-alpha/2,-for one tailed or two tailed tests, respectively; and the degrees of freedoms: numerator(n:df), denominator (d:df). See right tail areas, by UCLA.

Casio graphing calculator: Distributions, CHI, InvC. Area: alpha/2 and 1-alpha/2; df=n-1.

11. Confidence Interval for the Ratio of two Variances:

The confidence interval provides a range of likely values for the ratio between two population variances or standard deviations. If the confident interval contains one, we cannot conclude that the population’s variances differ.  It is given by:

Finding F  critical values: 



Casio graphing calculator: Distributions, F, InvF:  for F alpha/2, Right tail, enter the alpha/2, for Area; then the numerator df, followed by the denominator df. (Recall, the larger variance goes on the numerator).



For the left tail, enter the 1-alpha/2 value for area, and numerator df, denominator df.

Designing an Experiment, Power Analysis by Statsoft.com

"Performing power analysis and sample size estimation is an important aspect of experimental design, because without these calculations, sample size may be too high or too low. If sample size is too low, the experiment will lack the precision to provide reliable answers to the questions it is investigating. If sample size is too large, time and resources will be wasted, often for minimal gain. "

Probability: The Deck of Cards.

A deck of cards consists of 4 suits, 13 cards each for a total of 52 cards. The four suits are: Spades, Hearts, Diamonds, and Clubs. Each suit contains an A (Ace), numbers from 2 to 10, and three face cards: J, The Jack; Q, the Queen and K, the King.
Colors: Hearts and Diamonds are red, Spades and Clubs are black.

Statistical Intervals. Tolerance intervals.

A tolerance interval is a statistical interval within which, with some confidence level, a specified proportion of a sampled population falls (source, Wikipedia).

ANOVA table:

One-way ANOVA
Source of Variation SS df MS F
Between Groups SSB k-1 MSB=SSB/df F=MSB/MSW
Within Groups SSW n-k MSW=SSW/df
Total SST=SSB+SSW n-1    

SSB(between) =SST(treatments)
SSW (within)= SSE (residual errors)
Total sum of squares=Treatments sums of squares + sum of squares of the residual error.

Two way ANOVA
Source of Variation SS df MS F
Factor A SSA a-1 MSA=SSA/df MSA/MSE
factor B (blocks) SSB b-1 MSB=SSB/df MSB/MSE
Error SSE (a-1)(b-1) MSE=SSE/df
Total SST=SSA+SSB+SSE n-1    

SSB, sum of squares due to blocks: the sum of the squared differences between block means and the overall mean, multiplied by k, the number of treatments.

ANOVA regression: df SS MS F
Regression 1 SSR MSR=SSR/df MSR/MSE
Residual n-2 SSE MSE=SSE/df
Total n-1 SST=SSR+SSE    

Regression df: number indep vars (IP).
Residual df: number of data points(observations)-num ip-1. Simple linnear reg df=n-2; multiple linear regression: n-ip-1.
