The weights (in kg) of 22 students of a class are given below.
44, 46., 42, 40, 44, 44, 46, 43, 43, 44, 42, 46, 44, 43, 43, 42, 40, 40, 44, 46, 46, 44
Represent the data in tabular form using tally marks.

The marks obtained by 20 students of a class in a test (out of 50) are given below : 40, 44, 45, 46, 50, 42, 41, 8, 26, 28, 9, 32, 24, 6, 42, 36, 39. The range of the data is

Weights (in kg) of 15 students of a class are 38, 42, 35, 37, 45, 50, 32, 43, 43 ,40, 36, 38, 43, 38 and 47? What is the mean weight?

Weights (in kg) of 15 students of a class are 38, 42, 35, 37, 45, 50, 32, 43, 43 , 40, 36, 38, 43, 38 and 47? How many modes are there in the given data?

The weights (in kg) of 30 students of a class are 39,43,32,37,29,26,31,45, 46,31,37,38,30,39,36,41,35,34,41,46,39,38,36,38,40,42,33,43,44,33. Prepare a frequency distribution table using one class interval as 30-35 in which 30 is included and 35 excluded. using the above data, draw a histogram.

The weight of 10 students in kg is given below then find mode : 40,35,42,43,37,35,37,37,42,37

Find the median of the given data : 37, 31, 42, 43, 46, 25, 39, 45, 32

The weights (in kg) of 35 persons are given below :43,51,47,62,48,40,50,62,53,56,40,48,56,53,50,42,55,52,48,46,45,54,52,50,47,44,54,55,60,63,58,55,60,58,53. Prepare a frequency distribution table taking equal class size. One such class is 40 - 45 (where 45 is not included).

The weights (in kg.) of 15 students of a class are: 38,42,35,37,45,50,32,43,43,40,36,38,43,38,47(i) Find the mode and median of this data.(ii) Is there more than one mode?
