2. sum of squared deviations within?
3. df within ?
4. df between?

Answer 1

1. I think what Sneezy wants is a one-way ANOVA to determine whether there is a significant difference among the classes.
Easiest analysis is to use Excel:
Enter data in 4 columns with labels in first row.
/Tools > Data Analysis > ANOVA Single Factor > OK > Fill in dialog window with alpha = 0.05. This gives:
2. Within SS = 315, MS = 22.25
3. 12
4. 3
F-value = 7.98; P-value = 0.003

Answer 2

permit x and y be the two unknown numbers. x^2 + y^2 = x^3 + y^3 place a similar words on a similar element: x^3 - x^2 = y^2 - y^3 element out: x^2(x - a million) = y^2(a million - y) x^2 = 0 x = 0 If x = 0, then: x^2 + y^2 = x^3 + y^3 0^2 + y^2 = 0^3 + y^3 y^2 = y^3 y^3 - y^2 = 0 y^2(y - a million) = 0 y^2 = 0 y = 0 y - a million = 0 y = a million x^2(x - a million) = y^2(a million - y) (x - a million) = 0 x = a million If x = a million, then: x^2 + y^2 = x^3 + y^3 a million^2 + y^2 = a million^3 + y^3 y^2 = y^3 y^3 - y^2 = 0 y^2(y - a million) = 0 y^2 = 0 y = 0 y - a million = 0 y = a million on account which you probably did no longer specify your questions, permit's purely assume that the two numbers are diverse. if so, then the numbers are a million and nil :)

Answer 3

It's not clear exactly what your data mean. Are there 4 individuals who take some type of standard test for each attribute?
