step deviation for continuous series

Standard Deviation for continuous series - In this series too deviations may be taken either from the actual mean or from standard mean. The calculations will be simplified if the deviation are taken from assumed me..

In the discrete series, when deviations are taken from actual mean, the formula ..

Radioactive Decay Series - The emission of a or b - particles from a radioactive element results in the function of new element called daughter element. If the daughter element still has unstable nucleus, it further disintegrates by emitting a or b - particle and produces a new daughter e..

If a = assumed mean, then take the deviations of the items from a and call it ..

We know that every polynomial function is continuous and product of continues functions are continuous. f (x), being product of polynomials of degree 1, is a continuous function in [4,10..

Divide the total obtained in step 3 by the number of items and calculate the square root to get the standard deviation..

Multiply each frequency with corresponding deviation i.e., fd and obtain S f..

Find the squares of these deviations i.e., x 2 and obtain the sum of the square of deviation i.e..

For the third term, take coefficient as n C 2 , power of 'a' as n-2 and power of 'b' as 2. Continue this process repeatedly till the last term n C n a 0 b n is obtained..
