Suppose a drop of dye, with a concentration of 1 unit, is dropped at latex: x=0x = 0 at latex: t=0t = 0. at latex: t=5t = 5, the variance latex: (\sigma^2)( σ 2 ) of the concentration curve is found to be 20. estimate the diffusion coefficient latex: (d)

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
