The framework allows the use of correction factor for finite population and provide them appropriate feedback if the student has made use of it. Calculate the following: – The average population – the population standard deviation – Standard deviation sampling distribution
Population mean: mean = sum / average n = (23 + 28 + 24 + 22) / 4 = 97 / 4 = 24.25 standard deviation population = sqrt (sum (abs (mean – x) ^ 2) / n) = sqrt (((24.25-23) ^ 2 + (28 – 24,25) ^ 2 + (24,25 – 24) ^ 2 + (24,25-22) ^ 2) / (4)) = 2.28 SD = sqrt (sum (abs (mean – x) ^ 2) / n-1) = Sqrt ([(24.25-23) ^ 2 + (28 - 24,25) ^ 2 + (24,25 - 24) 2 ^ + (24,25-22) ^ 2] / (4-1)) = 2.63
