Usage: [p, Q]= chi2test by Peder Axensten(x)
The chi-squared test.
Given a number of samples this function tests the hypothesis that the samples are
independent. If Q > chi2(p, nu), the hypothesis is rejected.
Each column represents a variables, each row a sample.
If you find any errors, please let me know: .
x Absolut numbers.
p The prob ability value, calculated from Q.
Q The resulting Q-value.
In region A, 324 of 556 cows were red, whereas in region B 98 of 260 were red.
[p, Q]= chi2test 1.0([324, 556-324; 98, 260-98])
p= 4. 2073e-08
Q= 30. 0515
With an error risk of about 4e-08, we can claim that the samples are independent.
Throw two different dices to see if they have the same probability of 1 (and 2, 3, 4, 5, 6).
We don't check if they are symetrical, only if the both behave in the same way.
[p, Q] = chi2test [chi2test1.0.exe]([15, 10; 7, 11; 9, 7; 20, 15; 26, 21; 19, 16])
p= 0. 8200
Q = 2. 2059
The dices don't significantly behave differently. That is, they seem to behave in the same way.
