weighted average

Example

Find the weighted average of class grades (with equal weight) 70,70,80,80,80,90:

Since the weight of all grades are equal, we can calculate these grades with simple average or we can cound how many times each grade apear and use weighted average.

2×70,3×80,1×90

x = (2×70+3×80+1×90) / (2+3+1) = 470 / 6 = 78.33333

What is the consequence of changing over the condition? Completing every one of the changes recorded above can give either a condition that has indistinguishable roots from the first condition, or a condition, among the underlying foundations of which contains every one of the foundations of the first condition, however which can likewise have different roots, or a condition that does exclude every one of the roots underlying foundations of the changed condition. In the accompanying passages, we will dissect which of these changes under which conditions lead to which conditions. It is critical to know for the fruitful arrangement of conditions.
