In the one-way ANOVA where k is the number of treatments and n is the number of observations in all samples,the number of degrees of freedom for error is:
A) k - 1
B) n - 1
C) n - k
D) n - k + 1

The formula for the degrees of freedom for error in one-way ANOVA is:
df(error) = N - k
Where N = total number of observations and k = number of treatments.
We can also express N as n * k, where n = number of observations in each treatment.
Substituting this in the formula, we get:
df(error) = n * k - k
df(error) = k(n - 1)
Therefore, the correct answer is C, which is df(error) = n F1F1F1S1F1F1F10 k.
