1. ### Axioms of probability and sigma additivity

The third axiom of probability states that given an infinite sequence of mutually exclusive events A1, A2, .... we have P(A1 U A2 U ...) = P(A1) + P(A2) + ... (The probability of their union is equal to the sum of their probabilities) So take the following problem. I have a positive integer in...
2. ### Combining measures into 1 variable

I have 2 variables, one that measures (just for an examples) state aggression, and 1 that measures trait aggression. The state measure was responded to on a 6 point likert scale. The trait one was measured on a 5 point likert scale. Someone suggested that I combine these into one variable to use...
