10. Estimating the standard deviation or variancee Aa Aa 2.35.7 5.7 **7.78.9 10.1 10.6 11.1 11.312.0 12.1 12.4 12.8 13.9 18.6 Consider the sample of n = 20 scores. Notice that they are listed in order from 2.3 to 18.6, but that some of the scores are obscured by ***.The mean, M, of these scores is 10.0 Suppose you are asked for the sample standard deviation of these scores. Since you don't have all of them, you cannot calculate it. Which of the following is the best estimate of the sample standard deviation? O 16.3 O 8.1 0.6 O 3.6

Explanation / Answer

let we know that the varience and standard deviation is same for all the observation from my calculations best sample standard deviation will be fourth option ie 3.6
