Assume that you are a photographer. You want to click a picture of something in the dark. The object in discussion is a beautiful object, and it glows in the night light. What would you do? You click a picture. Analyze it. It’s still a black image. Now, having known about the shutter speed, you […]
Hello! In the third article of this series on the basics of statistics, we will understand what mode is and how we calculate the mode for a particular type of data. The mode is the simplest measure of central tendency. It is defined as the value that appears most frequently in a dataset. Unlike the mean (average)

The median is one of the most robust methods to measure the central tendency of a given distribution. It represents the exact middle value of the dataset, making it valuable when dealing with the outliers that skew the distribution. It is called the 50th percentile. Which means that we can divide it between the category

Definition of Central Tendency Central tendency is a statistical measure that identifies a single value representing the center or typical value of a data set. It aims to provide a concise summary of the entire distribution by locating the point around which most values cluster. The three main measures of central tendency are the mean, median, and mode. From

Many of you may have heard about binomial expansion (i.e., expanding a polynomial of two variables to their nth power). But what happens if we have to calculate ? If we start using the method of binomial expansion, it will take an extremely long time to reach the full polynomial. Hence, I am introducing a

Hexadecimal, or simply known as ‘hex’ in the computing world, is arguably the most widely used number system in firmware programming and control algorithms for various parts of robotic systems. The base used in this number system is 16, which means we calculate the decimal equivalent of hex numbers using powers of 16. {Note: Familiarity
The octal system, while less common than binary or hexadecimal in general programming, plays a crucial role in specific areas like Unix file permissions. It uses the number 8 as its base to denote the numbers. Also, it remains important in specific areas, such as setting file permissions in Unix/Linux systems (e.g., chmod 755). The
Everything about computers on the software level, programming level, etc., stems from this word. Binary means 0 and 1. It means whether the electrical signal is present or absent. In classical computers, these are the only two possibilities from which the entire digital world of information and computation emerges. Whenever you see a .bin file
The title of this article is in itself explanatory as to what is expected to be learned from this article. You must have seen that to denote the combination in mathematics or statistics, etc., as . This symbol means “the number of ways to choose ‘r’ objects from a total of ‘n’ objects. Let’s take
This is one of the very interesting topics, which can be used to learn and practice more about angles. Almost all of us wear watches and have clocks on the walls. A very simple circle, divided into 12 parts that give us the correct time, according to which we plan our daily tasks and maintain
