hello the question is late X1 X2 X3 telex and the an observation and it will be the and its Barbie the Arithmetic mean the standard deviation is given by in order to calculate the standard deviation we need to first calculate the variance so what is the variance we know that various average sum of square deviation deviation from mean deviation from mean what is variance is defined as a the formula the formula for variance formula for variance is

Singh is 1 mile in km equals to 1 2 x minus x square x minus b whole square The Princess this is the formula for variance because variant average of sum of square of deviation from mean to the sum of deviation of mean and when we have done that average and moreover we know that the formula for standard in using standard table in terms of variances standard deviation is equal to under root of variance so this is the formula for standard deviation in terms of variance so from here the final formula for standard deviation which we get is 1 by an summation I = 2 1 2 and x square minus x ka whole square

what is the formula for standard deviation and correct option the question is option number 3 so this is a solution 94 watching
