WebW = ∑ i = 1 n ( X i − μ σ) 2. Now, we can take W and do the trick of adding 0 to each term in the summation. Doing so, of course, doesn't change the value of W: W = ∑ i = 1 n ( ( X i − X ¯) + ( X ¯ − μ) σ) 2. As you can see, we added 0 by adding and subtracting the sample mean to the quantity in the numerator. WebFor example, you may wish to sum a series of terms in which the numbers involved exhibit a clear pattern, as follows: 1 + 2 + 3 + 4 + 5 + 6 + 7 or 1 + 4 + 9 + 16 + 25 + 36 + 49 The first of the examples provided above is the sum of seven whole numbers, while the latter is the sum of the first seven square numbers. osinachi nft
