Mean: The average value of the entire set of numbers.
Mode: The number which appears most often in a set of numbers.Median: The middle value between the largest and smallest in a set of numbers. Range: The difference between the largest and smallest in a set of numbers.
Interquartile range:
a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q3 − Q1.
