The median value is not affected by extreme scores and should also be reported.The mean is most affected by outliers in a study.In this case,the mean value is very close to values at one end of the scale and not toward the center,indicating that a normal curve is not present.The mode will describe the most frequent score.The range and variability will be reported,but do not describe central tendency.
