In fact these days it is difficult to find any research work without the diagram support. On the other side Graphs we generally make use of graph paper, In other words a graph represent mathematical relationship between two variables. Types of Diagrams: (1) One -Dimensional Diagram or Bar Diagram  (a) Simple Bar Diagram : In the simple bar diagram is used to represent only one variables. For example the figure o sales, production, population etc. The sales figure of Dell Co. as below:     (b) Sub-divided bar diagram : In a sub-divided bar diagram each bar represent the magnitude of a given phenomenon is further sub divided in its various components. For example the  students scored different marks in di

The mode or the modal value is that value in series of observations which occur with greatest frequency. For example the mode of series 3, 5, 8, 5, 4, 5, 9, 3 would be 5 , since that value occurs more frequently than any of other. Q 1 Calculate Mode with Individual Observation  Q 2  Calculate Mode  Q 2  Calculate Mode Continuous Series Quiz   Find the mean of the set of data. 3, 5, 7, 9,11 A: 5 B: 6 C: 7 D: 8 Find the median of the set of data. 15, 25, 28, 30, 17 Bottom of Form A : 25 B: 28 C: 30 D: 15 The ___________ is the middle value when the data are in numerical order, or the mean of the two middle values if there are an even number of items. A: mean B: mode C: median D: range The ___________ is the difference between the least and greatest values in the set of numbers. A: mean B: mode C: median D: range The ________ is the value or values that occur most often. A: mean B: mode C: median D: range The ____________ is the sum of the items divi
