frequency distribution

X-axis 1 cm = 10 marks Y-axis 2 cm = 10 c.f To reconstruct frequency distribution from cumulative frequency distribution. When we write, 'less than 10 - less than 0', the difference give the frequency 4 for the class interval (0 - 10) and s..

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 denoted by M.D. Formula for mean deviation for ungrouped data or..

Mean Deviation - 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 denoted by M.D. Formula for mean deviation for ..

Summary - The mean deviation (M.D) of a statistical data is defined as the arithmetic mean of the numerical values of the deviations of the items from some average. For an individual series, For a frequency distribution, If M.D is calculated about mean, then it is written as M.D (x)...

of a statistical data is defined as the positive square root of the arithmetic mean of the squared deviations of items from their arithmetic mean of the series under consideration. The standard deviation is denoted by s (sigma). The standard deviation is also known as Root Mean Square Deviatio..

.g., Out of 10 highest positive winter anomalies of air temperature in northern hemisphere, two heavy and one poor monsoon years are identified. Similarly out of 10 highest negative winter anomalies of air temperature, two heavy and three poor monsoon years are identified. The difference in mean ra..

Particle Nature of Light - According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron may escape the surface. If we u..

. f = e - E a / R T (22) The effect of this factor on k can be best explained with an example. Examples 13: The reaction of nitric oxide (NO) with chlorine (Cl 2 ) is believed to occur in a single step. The activation energy for the reaction is 8.5 x 10 4 J / mol. At 298 K the fraction of collision..
