CTET Solved Paper - CTET September 2016 Paper2
46. The mean of mode, median and range of the data 2, 1, 2, 3, 3, 6, 4, 8, 14, 9, 4, 8, 4 is
- Option : D
- Explanation : First of all rewrite the data in assending order 1,2,2,3,3,4,4,4,6,8,8,9,14 (13 numbers)
Now, median is the middle value,
There are total 13 numbers.
∴MedIan=13+1/2 = 14/2 = 7th term = 4
Mode: Mode is the number that isrepeated more often than any other.
So, 4 is the mode.
Range: Range is the difference between the largest and the smallest
number.
Range = 14 - 1 = 13
∴ Mean=4+4+13/3 = 21/3 =7
