Question

Which of the following statements are true? Select all correct answers. In a normal distribution, the mean, the median, and the mode are the same. The arithmetic mean of a distribution must always be an observed value in that distribution. The median cuts a distribution of scores in half at the 50th percentile. If we correctly summed all deviations from the mean of a distribution (without squaring those deviations), we will always obtain a sum of zero. Like the range, the interquartile range, is very susceptible to the influence of outliers.
