Mean, in Maths, is nothing but the average value of the given numbers or data.
Mean = Sum of the Given Data/Total number of Data
For example,
In a class there are 20 students and they have secured a percentage of: 88,82,88,85,84,80,81,82,83,85,84,74,75,76,89,90,89,80,82,83. Find the average of the percentage obtained by the class.
Solution: Average = Total of percentage obtained by 20 students in class/Total number of students
Avg = [88+82+88+85+84+80+81+82+83+85+84+74+75+76+89+90+89+80+82+83]/20
Avg.=1660/20 = 83
Hence, the average percentage of each student in class is 83%.
