  • Normal distribution (mean, median and mode are equal)
  • Skewed distribution
  Positive -mean is greater than the median and mode
  Negative -when the teacher taught very well and the students are highly motivated to learn the score distribution tends to be negatively skewed
• Variability
  • Range -difference between the largest and smallest value in the data set
  • Variance -the average square deviation of each number from the mean of the data set
  (May formula)
  • Standard Deviation -the square root of the variance (May formula)
• Difficulty index (formula)
