How to easily calculate average using average calculator

Good evening engpocket friends, on this moment, we are going to talk about average. Before we go ahead, you can use this average calculator to find your way to calculate average just in seconds.

How to problem solve using average calculating

Besides using the calculator, you can also use the average manual formula which we will talk about later in this post.

Example 1:
Find the average of the following scores: 80, 90, 75, 95.
Answer is:
$\begin{aligned} \text{Sum} &= 80 + 90 + 75 + 95 = 340 \\ n &= 4 \\ \text{Average} &= \frac{340}{4} = 85 \end{aligned}$

Example 2:
In a city, rain is falling over 3 days which was 12 mm, 15 mm, and 10 mm. What is the average rainfall?
Answer is:
$\begin{aligned} \text{Sum} &= 12 + 15 + 10 = 37 \\ n &= 3 \\ \text{Average} &= \frac{37}{3} \approx 12.33 \text{ mm} \end{aligned}$

Average formula

The problem solve and the average calculator above use the exact same formula which is:

$\bar{x} = \frac{\sum_{i=1}^{n} x_i}{n}$

Legend:

$\begin{aligned} \bar{x} &= \text{The Average (Mean)} \\ \sum x &= \text{The sum of all values} \\ n &= \text{The total number of values} \end{aligned}$

Oh, i almost forgot, we have not even known deeper about average…..

What is an average?

In math, average, specifically the arithmetic mean is the sum of a group of numbers divided by the quantity of those numbers. It represents a single value that summarizes an entire data set.

How to calculate the average?

This is the easiest steps that I can tell you about how to calculate average:

1. Divide the total sum by how many numbers.
2. Add up all the numbers.

Alright, are all of you now understands how to calculate average whether using average calculator or by calculate using manual formula. If engpocket friends want to try out our cube root calculator, you can move to this link.
