    Volume-weighted average/moment of a probability distribution function

    Hello,

    I would like to calculate the volume-weighted mean of an obtained fitted weibull distribution.
    For this, I thought about using the "third moment" of this distribution function and I want to make sure that the definition "3rd moment" corresponds to the I read a volume weighted average. The k-th moment, is defined as (with F(x) being the distribution function





    and since my volume weighted mean corresponds to x this should be (in my opinion) the 3rd moment.

    Am I completely wrong?

    In this case, could anyone tell me how to get the volume weighted average of a Weibull distribution?

    Thanks a lot!!!
