Is it true that if two variables are not linearly correlated then they are not related?

false they can be related with quadratic equation as well


Is women's intelligence proportional to the length of her skirt?

Skirt lengths and intelligence are randomly correlated having a correlation coefficient of zero to plus 0.15 ie knowing the measure of one does not predict the value of the other--they are independent variables. To say such and such are not correlated is to say you have not compared the variables. They may have identity with a value of plus one, or they may be inversely related having a value of negative one, or they may be randomly correlated with a value of zero--but to compare is to correlate.

How is saying that two variables are correlated different from saying saying that one caused the other?

Correlation and causality are not necessarily related. My age is pretty well correlated with the number of TV sets in the world. But neither of them is caused by the other. In this particular example, they both happen to be correlated to time, but there need not be such a factor. Conversely, let y = x2. Compile a set of pairs of x values, x = -m and x = +m and the corresponding y values, m2. Now, y is totally defined by x, but the correlation of y with x (not x2) for the above set of values will be zero. In this example x causes y but the relationship is not linear - the model is wrongly specified.


How do you calculate the density of an irregular object?

Determine its mass using a balance and determine its volume using water displacement. Then divide the mass by the volume to get density. Refer to the related link below for more detail.
