Arithmetic Mean example (Ungrouped data)
Let's
go through an example to illustrate the calculation of the arithmetic mean:
Suppose
we have the following dataset of exam scores for a class of students:
{85,
90, 95, 78, 69, 55}
To
find the arithmetic mean, we add up all the scores and then divide by the total
number of scores:
Therefore,
the arithmetic mean of the exam scores is 79 (approx.). This means that, on
average, the students scored 79 points on the exam.
