5*x=10
7*6=y
Here "x" and "y" are the variables.

the statistically independent random variables are uncorrelated but the converse is not true ,i want a counter example,
Examples of independent variables are:AgeRaceeducationWhy age is independent? because you can assign many variables that are dependent to age. Example: maturity, character, experience, and similar others.Race is also independent since many variables can be due to race. Example: color of the skin, language, belief, height, and similar others.But a race may also become a dependent variable if you relate it to- example the european continent. European continent now becomes the independent variable and races, beliefs, religions, and languages are dependent variables.
dependant and independent
Every time the independent variables change, the dependent variables change.Dependent variables cannot change if the independent variables didn't change.
