K stands for what?

Explanation:
In this context, K is the number of groups or levels of the factor you’re comparing. If you have four different treatment conditions, K equals 4. This notation shows up in one-way ANOVA to indicate how many groups you’re comparing, and it also links to the degrees of freedom between groups (df_between = K − 1) as you partition total variability into between-group and within-group parts. It’s not the total number of observations (that’s N), nor the number of variables, nor the degrees of freedom themselves.
