# Mean, Median and Mode with JavaScript

In this video, we are implementing algorithms for calculating the mean, median and mode of a dataset with JavaScript.

Before proceeding to coding, we briefly discuss how we can calculate each of these dataset properties.

Mean: in order to calculate the mean, all we have to do is to sum up all data points and divide by the number of data points. In other words, the mean, and more specifically the arithmetic mean (which is what we are calculating today), is what we usually call “the average” in everyday-life. Although, technically, mean, median, and mode are all kinds of averages, each trying to summarize the dataset with a single number representing a “typical” data point from the dataset.

Median: in order to get the median (the middle value), we first need to sort the dataset (conventionally in ascending order, but we would get the same result by sorting in descending order) and pick the data-point in the middle. If we had an even number of data points, we would get the mean of the 2 middle elements (by adding them and dividing by 2).

Mode: is the value in the dataset which occurs more frequently. If all values in the dataset appear with the same frequency, then the dataset has no mode. It is also possible for a dataset to have more than one modes.

Mean, median and mode, are different approaches for calculating the “typical” or “central” value of a dataset. That’s why they are also called measures of central tendency. Usually, they are used in conjunction with measures of spread (or measures of dispersion), in order to get the degree to which data is distributed around the center. Such measures of spread are the Range (which is the difference between the maximum and minimum value of the dataset) and Variance (or Standard Deviation which is the square root of Variance).

In this video, we are implementing algorithms for measures of central tendency. Feel free to expand on this, maybe by also calculating measures of spread and/or other statistical values. You could even take it a step further by creating a user interface such as a statistics calculator, which allows the user to enter a dataset and calculates and presents to the user a number of statistical values for the given dataset.

## How to Find Mean, Median, and Mode in Python?

Mean, median, and mode are fundamental topics of statistics. You can easily calculate them in Python, with and without the use of external libraries.

These three are the main measures of central tendency. The central tendency lets us know the “normal” or “average” values of a dataset. If you’re just starting with data science, this is the right tutorial for you.

By the end of this tutorial you’ll:

• Understand the concept of mean, median, and mode
• Be able to create your own mean, median, and mode functions in Python
• Make use of Python’s statistics module to quickstart the use of these measurements

If you want a downloadable version of the following exercises, feel free to check out the GitHub repository.

Let’s get into the different ways to calculate mean, median, and mode.

## Authentication In MEAN Stack - A Quick Guide

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.

To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.

Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

``````Angular demo runner
Online angular editor for building demo.
ng-run.com
<>
``````

Let me show what I mean…

### Template parser errors#

There are template parser errors that can be easy catched by stackblitz

It gives me some information but I want the error to be highlighted

## What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

## Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

## What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

## JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

``````<script type="text/javascript">
document.write("Hello World!");
</script>
``````

## How to comment JavaScript code?

• For single line comment in JavaScript we have to use // (double slashes)
• For multiple line comments we have to use / * – – * /
``````<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

</script>
``````
