To find mean of ungrouped data
It is obtained by adding the raw scores and dividing the sum by the number of items. Suppose the raw scores are x 1 , x 2 , x 3 ,, x N then, mean where M = mean x = each score or item N = number of items = sigma, which means 'summation of ' Find the mean of 6, 10, 4, 12, 8. M = 8 ..

Graphical Representation of Data
Graphical Representation of Data - Most people show lack of interest or have no time to go through facts and figures given in a daily newspaper or a magazine. But if these figures are graphically presented, they become easier to grasp and catch the eye and have a more lasting effect on th..
Graphical Representation of Data
The graphical representation of data makes the reading more interesting, less time-consuming and easily understandable. The disadvantage of graphical presentation is that it lacks details and is less accurate. In our study, we have the following graphs: 1. Bar Graphs 2. Pie Charts 3..
