While calculating mode the following observation are found. Lower limit of modal class =40, frequency of modal class =20, frequency of previous class =12 , frequency of preceding class =11 and width of the class =10, find mode .

The distance (in km) of 40 engineers from their residence to their place of work were found as follows: 5 3 10 20 25 11 13 7 12 31 19 10 12 17 18 11 32 17 16 2 7 9 7 8 3 5 12 15 18 3 12 14 2 9 6 15 15 7 6 12 Construct a grouped frequency distribution table with class size 5 for the data given above taking the first interval as 0-5 (5 not included). What main features do you observe from this tabular representation?

The marks obtained (out of 20) by 30 students of a class in a test are as follows: 14, 16, 15, 11, 15, 14, 13, 16, 8, 10, 7, 11, 18, 15, 14, 19, 20, 7, 10, 13, 12, 14, 15, 13, 16, 17, 14, 11, 10, 20. Prepare a frequency distribution table for the above data using class intervals of equal width in which one class interval is 4-8 (excluding 8 and including 4).

For the following data of daily wages (in rupees0 received by 30 labourers in a certain factory, construct a grouped frequency distribution table by dividing the range into class intervals of equal width, each corresponding to 2 rupees, in such a way that the mid-value of the first class interval corresponds to 12 rupees. 14,16,16,14,22,13,15,24,12,23,14,20,17,21,22,18,18,19,20,17,16,15,11,12,21,20,17,18,19,23

Let the marks obtained by 30 students of a class in a test be 38, 26, 4, 32, 20, 22, 11, 47, 12, 23, 8, 2, 10, 8, 12, 17, 2, 19, 16, 42, 40, 13, 47, 38, 17, 27, 30, 6, 23, 18. Arrange the data in grouped frequency distribution, using groups 0-10, 10-20 e tc.

Construct a frequency table with class-intervals 0-5 (5 not included) of the following marks obtained by a group of 30 students in an examination: 0,5,7,10,12,15,20,22,25,27,8,11,17,3,6,9,17,19,21, 29,31,35,37,40,42,45,49,4,50,16.
