In a distribution of scores for which the mean = 65.5, median = 64, and mode = 60, it was found that a mistake had been made on one score. Instead of 70, the score should have been 90. Consequently, which of these measures of central tendency would certainly be changed? a. Mean, b. Mode, c. Median, or d. Can't tell
