Are any of the measures of dispersion among the range, the variance, and the standard deviation, resistant? Explain. Choose the correct answer below. O A. Yes, the variance is resistant because it has squared units, so is always positive. OB. No, all of these measures of dispersion are affected by extreme values. OC. Yes, the standard deviation is resistant because it is calculated using the mean, which is resistant. OD. Yes, the range is resistant because it always includes all...
