Step 1
Z-scores measure how many standard deviations a value is from the mean; in particular the z-score of the mean is (mean − mean)/SD = 0. Show more…

Which of the following is false? 1) The majority of Z scores in a right-skewed distribution are negative. 2) In skewed distributions, the Z score of the mean might be different than 0. 3) For a normal distribution, IQR is less than 2 x SD. 4) Z scores are helpful for determining how unusual a data point is compared to the rest of the data in the distribution. Explain why, please!
Which of the following is false? Hint: It might be useful to sketch the distributions. A. The Z score for the median of a symmetric distribution is approximately 0. B. The Z score for the median of a left skewed distribution is negative. C. Z scores are defined for observations from distributions of any shape and skew. D. Calculating percentiles based on the Z table is only appropriate for observations that come from a nearly normal distribution.
