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

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
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
In this short article, we will explore the idea of exponents a little further and see some important values of the exponents of the first ten natural numbers (1 to 10). This data can be used in probability theory for finding the sample space of multiple coins or dice thrown simultaneously. Powers of 2: Powers
In daily life, people often interchange the words ‘possibility’ and ‘probability’. However, these words are NOT interchangeable. “Possibility” is used when there is something that is said in qualitative terms (mostly as a vague statement). It is related to most of the tasks, which are assessed to determine whether or not they are possible to

This topic is pretty basic, but its applications are endless in real life. This very term (percentage) is used in countless comparisons, competitions, and evaluations. It is also used in experiments and applications of mathematical and physical laws in laboratories to measure accuracy or inaccuracy for drawing conclusions. The word percentage comes from the Latin
We know that multiplication of numbers can be visualized as repeated addition of the same number.For example, We can visualize 76 multiplied by 87 as the number ’76’ added 87 times to itself, or the number ’87’ added 76 times to itself. The numerical multiplication is therefore called ‘commutative‘ (a times b = b times
