Find the mean from the following obtained marks of the student after constructing a frequency distribution table .

1,5,6,9,8,4,1,9,8,4,5,4,5,6,5,4,1,5,4,6​

Sagot :

Mean = 8

The mean is the average number in a sequence. To find the mean we can simply use the following equation

(Sum of all numbers) ÷ (Amount of numbers)

The sum of the given numbers is 160

The amount of numbers is 20

So the mean = 160 ÷ 20 or 8.
