Q9 of 55 Page 364

If the mode of data 16, 15, 17, 16, 15, x, 19, 17, 14 is 15, then the value of x is

Mode of the data is the value that occurs most of the time in data

Now we can see from data given to us that 16 occurs 2 times and 15 occurs 2 times, rest of the values occur only 1 time


So, for 15 to be the mode of data, 15 should occur three times and this can happen only when x = 15


So, x = 15

If 35 is removed from the data 30,34, 35, 36, 37, 38, 39, 40 then the median increases by

 9

If the median of arranging the ascending order of data 8, 9, 12, 17, x + 2, x + 4, 30, 31, 34, 39, is 15, then the value of x is

 9

Let us write true or false of the following statements :

i. Value of mode of data 2, 3, 9, 10, 9, 3, 9 is 10


ii. Median of data 3, 14, 18, 20, 5 is 18
