Homework Help: Statistics and independent variables

  1. Jul 2, 2012 #1
    1. The problem statement, all variables and given/known data
    Let's say the independent variable (in statistical terms) A depends on variables B, C and D. We perform tests, and find out that the variable A causes "something" with the values of B, C and D equal to B2, C2 and D2.

    Let's also say that A with variables B, C and D of B1, C1 and D1 won't cause "anything" (as in, won't cause "something").

    How does one deal with such problems in statistics? Whenever some variable depends on other variables to a great extent (even if these variables aren't external), is it usually said that it has been concluded that variable A causes something ONLY with variables B, C and D equal to B2, C2 and D2?

    Or is it said that variable A causes something, regardless of the variables that it depends on?

    2. Relevant equations

    3. The attempt at a solution

    So you discover that A is not an independent variable? It might better serve your query if you were to come up with a real world example to illustrate your question, and also indicate what year of maths you are studying at school.

    Perhaps the word "correlates" might be useful here, as it doesn't ascribe a causal relationship. (Example: the height of a man correlates strongly with the length of the trousers he buys.)
