Answer : Option ( B )
No, all these measures of desperation are affected by extreme values
Because resistant meaning Extreme values relative to the data set do not affect its value substantially .
Are any of the measures of dispersion among the range, the variance, and the standard deviation,...
3.2.53 What makes the range less desirable than the standard deviation as a measure of dispersion? Choose the correct answer below. O A. The range is resistant to extreme values. OB. The range does not use all the observations. O C. The range is biased. OD. The range describes how far, on average, each observation is from the mean.
Find the range, variance, and standard deviation for the given sample data, if possible. If the measures of variation can be obtained for these values, do the results make sense?

What is the main difference between the variance and the standard deviation as measures of variability? standard deviation is variability around the median, whereas variance is variability around the mean standard deviation is squared variability around the mean, whereas variance is in the original units variance is for the population, whereas standard deviation is around the sample mean. variance is squared variability around the mean, whereas standard deviation is in the original units

10. Properties of the standard deviation and range Aa Aa E Which of the following is a true statement concerning the standard deviation? Check all that apply. The standard deviation provides a measure of the spread between the two most extreme scores in distribution The standard deviation is more subject to sampling variation than the range. It is more complex to compute the standard deviation than the range. A researcher is studying psychological factors in artistic achievement among teenage girls....
