Range The range is the simple method of studying dispersion. It is defined as difference between the value of the smallest item and the value of largest item included in the distribution. Range= L-S L= Largest Item S= Smallest Item Coefficient of Range = L-S/L+S Que 1. Calculate Range and its coefficient Sol Range= L-S L = 250 S = 160 Range = 250-160 = 90 Coefficient of Range = L-S/L+S = 250-160/250+160 = 90/410 ...

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.

The median is defined as the middle value in an distribution, it is important to keep a note that before to calculate median one should arrange the frequency in ascending or in descending order for example the income of five employees is 900, 950,1020, 1200 & 1280. The mid value is 1020. In the case of even number of series the income of six employees are 900, 950, 1020,1200, 1280, 1300. Now in the case of even values the middle values are 1020 and 1200 Median = 1020+1200/2 Median = 2220/2 Median = 1110 Q 1. Calculate median with Individual series Q 2.
