Mean of 100 observations is 50
WebThe value of the largest observation is 100. Mean = Σ f x Σ f. ⇒ 50 = Σ f x 100. ⇒ Σ f x = 5000. It was later found that it is 110 not 100. Correct, Σ f x ′ = 5000 + 110 - 100 = 5010. Therefore, Correct Mean = Σ f x ′ Σ f = 5010 100 = 50.1. It is given that the median of 100 observations is 52. Median will remain same i.e. = 52.
