Average Rating Calculator

An average rating calculator is a tool that calculates an average rate for something you choose to rate, and it works on a scale from one to five.

In this article, you can learn about the average rating. CalCon team developed an app that is simplifying this process even more. Walking through the following text, you will understand the background of calculating the average rate, which works as an average calculator.

What is the average rating?

Let’s imagine the following situation. It’s bright and shiny outside, the birds are singing, you are spending a delightful time online surfing on the site CalCon calculators when suddenly you realize that above every text, there are five fulfilled golden stars. Your curiosity is suddenly increasing, the desire for knowledge is aching, and while your palms are sweating, you start typing what that could mean. Surprise! Guess who is delivering the best answer for you? Also, the CalCon calculators site, which is free and helpful. And not only that, but we also have an app where you can do some new calculations independently. Have fun trying them out.

The average itself, also named arithmetic mean, is the sum of the list of numbers divided by the count of numbers. Additionally, the median is slightly relevant to this topic, and it is the middle value of a properly arranged data list.

The average rating is the process where something is being graded, for example, on a scale from one to five (usually as star). After collecting the sum of all rates, they are then divided by the number of times something was rated, that is, by the number of votes. In other words, the average rate is the final rate, which results in a quotient of the sum of all rates and the number of votes (entry data). We use these ratings to gain a better insight into the quality of the observed issue.

The average rating formula

The average rating formula consists of the number sequence, whose sum is the dividend and the number of members of the sequence is the divisor. Therefore, the average rate results from dividing those values.

The formula for the average rating is:

 x= \frac{x_{1}+x_{2}+...+x_{n}}{n} 

Where:

x – is the average rate (score),

x_{1} to x_{n} – are the rates entered,

n – the number of votes.

Our calculator is based on ratings from one to five, and its mathematical principle is displayed in the following formula:

AR= \frac{1\cdot x_{1}+2\cdot x_{2}+3\cdot x_{3}+4\cdot x_{4}+5\cdot x_{5}}{5}

Where:

x_{1} – the number of times when something was rated with the grade one,

x_{2} – the number of times when the rate was two, x_{3}, x_{4}, and x_{5} – the number of times the grade was three, four and five, specifically in this order.

You have an average rating calculator in the right upper corner of this page. It is easy to use, and you get the result only by applying one step; you need to enter the number of votes alongside the rating category. By fulfilling this step, the calculator automatically gives you the result of the average rate.

How to calculate an average rate?

We will explain how to calculate an average rate on an example of a blog post. So, the option to rate the article is enabled, and we will focus solely on fifteen readers. Six of them really liked the writer’s approach to the imaginary topic we are rating today, while two thought it was a waste of time and energy to read it. So the first six visitors gave five stars to rate the writer’s effort; those two disappointed ones gave one star each. The rest of them had their pros and cons, and according to them, rated the article in this order: three thought that four stars are enough, two were okay with three stars, and the remaining two votes gifted the article with two stars.

So, the formula will have this form after inputting these values:

 AR= \frac{6\cdot 5+3\cdot 4+2\cdot 3+2\cdot 2+2\cdot 1}{15}

AR=3.47

You can also get this score on our calculator; the only difference is that it works way faster than calculating by hand. In my personal opinion, this imaginary blog post has solid success. On a scale from one to five, fifteen of its readers rated the content 3.47.
That is how average ratings work. It is a simple process but worthy; it is mostly used as an online indicator for quality. With this in mind, do the future ratings carefully; each star higher means that you compliment something more. Use our calculator to improve the average rating and the arithmetic mean knowledge.
