Okay, in this question, we want to know what the mean is.
00:04
So basically, explain the definition of mean, what the formula is to calculate it, and we're going to calculate it for the following dataset, a, of numbers 43, 187, 34, and 24.
00:18
So basically, mean is the central or typical value in the dataset.
00:22
So when we add up all of these numbers right here, and then divide it by the number of elements in the set, we'd find out what that central or typical value in the dataset is.
00:33
And the formula for this in a visual representation here is simply e of x, so summation of the entire data set right here, all over the number of elements in the data set.
00:44
So 1, 2, 3, 4, 5.
00:47
So in this case, n is equal to 5...
