KHAN ACADEMY ALGORITHMS LIST 2024 WITH COMPLETE SOLUTION A statistician developed this procedure to calculate the "variance" of a list of numbers. The variance is a statistical quantity that corresponds to the average of the sum of the squared differences of each number from the mean. As input, the procedure takes a list of numbers and its mean: PROCEDURE calculateVariance(numbers, mean) { count ← 0 sumSquaredDiffs ← 0 FOR EACH num IN numbers { diff ← (num - mean) squaredD...
