Choose all that apply. Mean Median Mode None of these measures (b) Suppose that the measurement 28 (the smallest measurement in the data set) were replaced by 7, Which measures of central tendency would be affected by the change? Mode Choose all that apply. Mean Median Mode None of these measures (c) Suppose that, starting with the original data set, the smallest measurement were removed. Which measures of central tendency would be changed from those of original data set? Choose all that apply. Mean Median Mode None of these measures (d) The relative values of the mean and median for the original data set are typical of data that have a significant skew to the right. What are the relative values of the mean and median for the original data set? Choose only one. Mean is greater Median is greater cannot be determined
