WebbStandard deviations for first 10 natural numbers is 2.87.. Explanation: We know that S.D. of first n natural numbers `sqrt((n^2 - 1)/12)` Here n = 10. ∴ S.D. = `sqrt((10)^2 - 1)/12` WebbIn plain language, it is meaningful to say that 20 Kelvin is twice as hot as 10 Kelvin, but only in this scale with a true absolute zero. While a standard deviation (SD) can be measured in Kelvin, Celsius, or Fahrenheit, the value computed is only applicable to that scale.

Prove that the standard deviation of the first n natural numbers is …

WebbIn a college entrance exam, the participants are rated as excellent, very good, good, and fair. Consider that the scores in the exam are normally distributed with a mean of 78 and … WebbThe standard deviation is divided by the coefficient of variation to calculate. 📌. The mean of squared deviations which is calculated from arithmetic mean is called. 📌. The coefficient … WebbSolution: Mean of first n natural numbers when n is odd =2n(n+1) ∴ Mean deviation =n∑∣xi−x∣ =n1[(1−2n(n+1))+(2−2n(n+1))+…(n−2n(n+1))] =n2[1+2+…2n−1] This is a series of first 2n−1 numbers, ∴n2[1+2+…2n−1]=n2(2(2n−1)(2n−1+1)) =n2(8n2−1) =4nn2−1 ,which is the required mean deviation. 150 Still did not understand this question? offset axle
