Mathematics is more than just a school subject—it is the language of problem-solving, logic, and innovation. From engineering and data science to finance and artificial intelligence, math lies at the heart of every cutting-edge discipline. But here’s the challenge: many students struggle to build a deep conceptual understanding of math, and this gap often limits […]

When data is large, instead of writing down every observation, we often organize it into a frequency distribution table. The measures of central tendency (Mean, Median, Mode) can then be calculated using special formulas for grouped data. In this article, we’ll explain each measure in detail with examples. 1. Mean of Grouped Data Formula (Step-Deviation […]

Mathematics is more than equations—it is the foundation of problem-solving, logic, and innovation. For ambitious students in the United States, mastering math opens doors to Ivy League admissions, scholarships, Olympiad success, and future careers in STEM. As an alumnus of IIT Guwahati and the Indian Statistical Institute, published author, and passionate educator with 6+ years […]

I am excited to share the release of my latest Kindle eBook — Systems of Equations: The Art of Simultaneous Solutions, now available on Amazon. This book is born out of years of teaching mathematics to ambitious students across the globe. It reflects not just methods and formulas, but the art of problem-solving — how […]

Algebra is the language of modern mathematics — the foundation that supports calculus, statistics, and all advanced mathematical thinking. Whether you’re preparing for the IB Diploma, A-Level Math, or AP Calculus and Statistics, a deep, conceptual understanding of algebra is essential. If you’re a student (or a parent of one) aiming for Oxbridge, Ivy League, […]

When we talk about statistics, most students are familiar with the measures of central tendency such as mean, median, and mode. But these only tell us about the center of the data. To understand how data is spread out, we need the measures of dispersion. This blog explores dispersion in detail — from definitions and […]
