WebApr 21, 2024 · Next, to calculate the variance, we take each difference from the mean, square it, then average the result. Variance = ( (-3) 2 + (-2) 2 + (-1) 2 + 2 2 + 4 2 )/ 5. = (9 + 4 + 1 + 4 + 16 ) / 5 = 6.8. So, the variance is 6.8. And the standard deviation is the square root of the variance, which is 2.61. What this means is that, on average, you and ...
WebWell, there are two ways for defining the variance. You have the variance n that you use when you have a full set, and the variance n-1 that you use when you have a sample.. The difference between the 2 is whether the value m = sum(xi) / n is the real average or whether it is just an approximation of what the average should be..

WebMean = (Σf×X) / Σf = 526.5 / 23 = 22.89. Therefore, the mean of the given grouped data is 22.89. (ii) Median: To find the median of a grouped data, we need to first find the cumulative frequency and then determine the class interval that contains the median. We can then use the following formula to calculate the median:
