The book by M. Nurul Islam is a widely used academic text that covers descriptive statistics, probability theory, and inferential methods.
The heart of the book. Here, the author explains how to use sample data to make conclusions about entire populations: non-random sampling techniques and standard error
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1 that represents the chance or probability of an event happening. A probability of 0 indicates that the event is impossible, while a probability of 1 indicates that the event is certain. Probability is used to model and analyze random phenomena, such as coin tosses, dice rolls, and stock prices.
This section teaches readers how to locate the "center" of a data set. Deep dives into Arithmetic Mean, Median, and Mode. Specialized applications of Geometric and Harmonic Means.
Here are some common probability distributions: Over a multi-decade career
The humid air of the Dhaka University library felt thick with the scent of old paper and ambition. Amina scrolled frantically through her phone, her thumb aching from the repetitive motion. She needed it—the holy grail of her semester— An Introduction to Statistics and Probability by M. Nurul Islam.
Dr. M. Nurul Islam is a distinguished academic who served as a Selection Grade Professor of Statistics at the , Bangladesh. Over a multi-decade career, he has served as the Chairman of the Department of Statistics and later as the Pro-Vice Chancellor of the World University of Bangladesh. His teaching experience shines through the book’s structured layout, which is designed to prevent students from feeling overwhelmed by abstract mathematics. Core Structure of the Book
