CENTRAL TENDENCY (MODE)

                   (MODE)
                 ***********

1) Following is the data of the heights of a group of students: 61,62,63,64,60,65,63,64,64,66,64. Now suppose that a group of students whose heights are 60,96, 59,68,67, and 70 inches is added to the original group.
a)What is the mode of the
     combined group ?

2) Mode of 5,3,27,5,9,3,8,5.

3) Mode of 4,3,2,5,3,4,5,3,7,3,2,6.

4) Mode and median of 25, 1275, 162,967,162.

5)Mode of 2, 1, 4, 2, 6, 4, 3, 2, 8,2,
      2, 1,4,6

6) mode of 1, 2, 2, 3, 3, 3 ,3, 4, 4,
      4,4,5,5,

7) Find Mean, Median, Mode of
       4,6,10,12,14,14,20,22.

8) The median of a set of observations is 12.Their mean is 13. Find their Mode.

9) The mode of 3,4,5,3,6,5,x,3,4,3.

10) If mean and mode is 26 and 24
       find  MEDIAN

11) For a moderately symmetric distribution the difference between mode and median is 24. Find the difference between median and the mean of the distribution.

12) For a moderately symmetric distribution the difference between mode and median is 24. Find the difference between median and the mean of the distribution.

13) X:   0     1      2    3     4     5
