. Which of the following statement is not correct and why? A. For normal distributions, the mean is the most efficient. B. Mean is good for skewed distributions because it takes into consideration of all the possible scores. C. Median is less sensitive to extreme scores than the mean. D. Mode becomes rather unimportant as a statistic when the distribution is multimodal. If the largest observation in a set scores is 99 and the smallest is 71, what is the range, show work? A. 1 B. 28 C. 71 D. 99 Which of the following statement is correct and why? A. The median is the mean trimmed 0% and the arithmetic mean is the mean trimmed 100%. B. A trimmed mean is calculated by discarding the lower and higher 25% of the scores then dividing the sum of the remaining scores by 2. C. Trimean is not a good measure of central tendency. D. One advantage of using trimean is their resistance to extreme scores.
