According to the question: Mean = 11. ⇒ ( n + 1) ( 2 n + 1) 6 = 11 ⇒ 2n 2 + n + 2n + 1 = 66 ⇒ 2n 2 + 3n - 65 = 0 ⇒ 2n 2 + 13n - 10n - 65 = 0

Taking square root of it leads to estimating standard deviation. I guess that mean squared deviation and root mean squared deviation are used more commonly in machine learning field where ... Splet09. maj 2024 · The key to the elementary solution is that we are separating out the total sum of squares into a main component (the square of the means), plus a residual component (the sum of squared deviations from the mean).
