Given that Set X:{5,6,9} and Set Y:{0,1,4} and we need to find SD(Standard Deviation) of Set X and Y
Theory: SD(Standard Deviation) is an indication of how spread the numbers are as compared to the Mean
Quantity A: SD of set X
We have three numbers 5, 6 and 9 with the numbers at an incremental distance of 1 (5 to 6) and 3 (from 6 to 9)
Quantity B: SD of set Y
We have three numbers 0, 1 and 4 with the numbers at an incremental distance of 1 (0 to 1) and 3 (from 1 to 4)
Since both the Sets are equally spread (They will be equally spread around the mean too)
=> Both have same SD
=> Quantity A = Quantity B
So, Answer will be C
Hope it helps!
