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

Find the mean, variance and standard deviation for the number of heads, when 20 coins are tossed. => 10, 5, 5 or 5, 5 2 , 5 2 or 10, 5 , 5 or 5, 5 2 , 5 2..

A survey asks 'How much time do you spend in front of the TV in one week? Suppose the responses are normally distributed, the mean is 10 hours and the standard deviation is 2 hours. What value in hours is one standard deviation above the mean..

Merits: - Mean deviation is easy to calculate. This measure is simple to understand. This can be calculated from any average. Its value is based upon all the (observations) items of the data. It is less affected by extreme observations. It gives us an idea about how the items ar..
