A die is thrown and a coin is then tossed as many times as the number shown by the die. What is the probability of getting more number of heads than tails?
(47 ,87,77,97) / 192

Is there any forum where I can post "Similar Words with Different Meanings" ???
@YouMadFellow said:Statistics:Mean: For given number of observations, the mean is Sum of all observations divided by the number of observations. OR Mean = Sigma( x(i) * f(i) ) / Sigma( f(i) ), where f(i) is the number of occurrences of x(i).Median: Write the numbers in increasing order first. If there are odd number of numbers (n), then the median is the (n+1)/2 the observation. If there are even number of numbers (n), then the median is the average of n/2 th and n/2 + 1 th observation.Mode: The number which occurs most number of times in the set of numbers. There can be multiple modesVariance: Let the average be A and each observation be x(i), then the variance is given by1/N * (Sigma ((x(i) - A)^2)) ) , where N = number of observationsStandard Deviation: It is simply the square root of variance. To remember this and avoid confusion, remember S for Square root and S for standard deviation@hanushanand @aimingCAT12 @fisherking @Estallar12 - confirm karo..
For Variance
Are u guys sure that the factor of multiplication is 1/N and not 1/N-1. ??
I remember it as 1/N-1.
Cross checked using wolfram for the data set {2,3,4,4,5,6}
its giving 10/5 not 10/6.
Just see if I am missing sumthing.

I can be both 1/N and 1/(N-1).. N when we talk of a simple data set.. (N-1) when talk of a sample of a big data set, though I am not sure what does that mean, may be others can throw some light on it... In our case, I didn't find the reason to do a (N-1) .. so I wrote N..

It's 1/N the N-1 is for different not cat related stuff which I don't understand :p
