Moments in Statistics

Second moment about mean gives:

The moments about mean are termed as:

The first moment about means is always:

If first four raw moments of a distribution about the value $5$ of a variable are $1, 10, 20$ and $25$. Find the third central moments.

If first four moments of a distribution about the value $5$ of a variable are $1, 10, 20$ and $25$. Find the first four moments.

The first four moments of a distribution about the value $5$ of a variable are $1, 10, 20$ and $25$. then the central moment, ${\beta }_1$(upto $3$ decimal places) is _____.

The first four moments of a distribution about the value 5 of a variable are $1, 10, 20$ and $25$. Find the central moments,  ${\beta }_2$.
