Mean = Average
x = Sum of all the total observations / Total number of observations
E.g. when a student scores 48, 40, 42, 36, 44 out of 50.
No of subjects = 5
Mean = (48 + 40 + 42 + 36 + 44) / 5 = 210/5 = 42

Median = Middle value or Middle Observation
E.g 17, 2, 7, 27, 15, 5, 14, 29
Formula for Odd nos. - (n+1)th/2
