mean average calculation

The average rate of reaction is calculated by determining the difference in [O 2 ] concentration over different intervals of time and dividing the difference by D ..

Example 2: The gaseous phase decomposition of dinitrogen pentoxide (N 2 O 5 ) to nitrogen dioxide (NO 2 ) and oxygen (O 2 ) is given by, For the reaction the concentration of O 2 was monitored and the following data were obtained. Time/s 0 600 1200 1800 3000 4200 [O 2 ] M 0 0...

Mean - Mean is the arithmetic average..

Mean is the arithmetic average. To find mean of ungrouped data and it is obtained by adding the raw scores and dividing the sum by the number of items. There are three methods to find mean for a frequency distribution. (i) Direct method, (ii..

When we travel in a vehicle the speed of the vehicle changes from time to time depending upon the conditions existing on the road. In such a situation, the speed is calculated by taking the ratio of the total distance traveled by the vehicle to the total time taken for the journey. This i..

The three molecular speeds are expressed as ..

Merits: 1. Mean deviation is easy to calculate. This measure is simple to understand. 2. This can be calculated from any average. 3. It is less affected by extreme observations. Demerits: 1. This is mathematically incom..

Calculation of Standard Deviation for discrete series - In the discrete series, when deviations are taken from actual mean, the formula ..

The mean deviation of a statistical data is defined as the arithmetic mean of the numerical values of the deviations of items from some average value. Mean deviation is also known as average deviation . The mean deviation is generally deno..
