sum of all deviation

Mean Deviation of a data value is ______ . => how much it differs from the mode. or sum of all the data values. or range of the given data set. or how much it differs from the mean...

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

1. The Arithmetic mean is obtained by dividing the sum of all the items in the list by the total number of items. 2. There are three methods to find mean for a frequency distribution. (i) Direct method, (ii) Short-cut method, (iii) Step-deviation method...

Module Three: Anticipating Patterns - Probability: Interpreting probability, including long-run relative frequency interpretation 'Law of Large Numbers' concept Addition rule, multiplication rule, conditional probability, and independence Discrete random variables and their probability distribution..

Power of a Lens - Whenever a ray of light passes through a lens (except when it passes through the optical center) it bends. The bending of light rays towards the principal axis is called convergence and bending of light rays away from the principal axis is called divergence. The degree of converge..

Summary - The Arithmetic mean is obtained by dividing the sum of all the items in the list by the total number of items. Direct method M = Where x is mid-interval f is frequency M is mean Short cut method where A = assumed mean d = x - A Step deviation method Where i = class siz..

The sum of infinite number of sine waves Plot of the relative amplitudes. G( w ) is a Gaussian function with mean equal to v and standard deviation ..

Power of a lens is defined as the ability of the lens to converge or diverge a beam of light falling on the lens. Power of lens is given by reciprocal of focal length of the lens i.e., When f = 1m, p = 1 dioptre For a converging lens or convex lens, P is + and for a diverging lens or concave lens, ..
