We could then calculate the variance as: The variance is the sum of the values in the third column. Thus, we would calculate it as: WebFinding mean x i f i f i x i 92 3 276 93 2 186 97 3 291 98 2 196 102 6 612 104 3 312 109 3 327 ∑ f i = 22 ∑ x i f i = 2200 Mean ¯ ¯ ¯ x = ∑ x i f i ∑ f i ⇒ ¯ ¯ ¯ x = 2200 22 ⇒ ¯ ¯ ¯ x = 100 Finding variance and standard deviation For x i = 92, f i = 3, ¯ ¯ ¯ x = 100, x i − ¯ ¯ ¯ x = 92 − 100 = − 8, (x i − ... have a great day penguin
