Explanation
Step -1: Describing Measures of central tendency.
As central tendency is a tendency for a set of values to gather around the middle of the set.
And mean, median and mode all three are the measures of central tendency.
Step -2: Finding the correct option.
But class interval is the numeric width of any class in a particular distribution.
So, option A, B, D are the measures of central tendency.
And option C is not a measure of central tendency.
Hence, the correct option is C.
Step -1: Listing first 10 odd natural numbers .
First 10 odd natural numbers = 1, 3, 5, 7, 9, 11, 13, 15, 17, 19
Step -2: Calculating mean
We know that, mean of n numbers = Sum of n numbersn
∴ Mean of first 10 odd natural numbers,
M = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 1910
⇒ M = 10010 = 10
Thus, the mean of first 10 odd natural numbers is 10 .
