Time 2 hours Maximum Marks 50 Weightage 70%
Note: There are three sections and all are compulsory.
SECTION
1. Fill in the blanks with appropriate word(s) given in brackets 5x1=5 In random sampling every unit of the universe has chance of selection. (equal/unequal) A less than ogive has a tendency to (rise/fall). Greater the value of a measure of variation, is the degree of uniformity in the data. (smaller/larger) Rectangles are an example of dimensional diagram. (one/two) The number of typing errors on a page is an example of variable. (discrete/ continuous)
2. State whether the statements given below are True or False. 5x1=5 There is no difference between census and sample enquiry. One dimensional diagram represents only length. The data need not be arrayed before determining the median value. The sum of absolute deviations is the least from median. In a symmetrical distribution, the value of mean, mode and median is always unequal.
SECTION
