Join us as we explore the fascinating journey of statistics, from its humble beginnings in ancient civilizations to its indispensable role in today’s data-driven world. We’ll trace the evolution of this vital field, highlighting key milestones and the brilliant minds that shaped it.Discover how early civilizations, including the Egyptians, Romans, and Chinese, used rudimentary forms of statistics to record population, wealth, and resources for taxation and administration. We’ll then travel through time to the 16th and 17th centuries, where probability theory emerged from the world of gambling and mathematicians like Blaise Pascal and Pierre de Fermat laid the foundation for statistical inference.We’ll meet John Graunt, the pioneering English statistician who revolutionised demographic analysis with his groundbreaking work on mortality bills in 17th-century London. His insights sparked further exploration into political arithmetic, life expectancy calculations, and the development of life insurance mathematics.The 18th century marked a turning point in the history of statistics. It was during this period that the word "statistics" was coined, first in German by Gottfried Achenwall in 1750 and later in English by Dr. E. A. W. Zimmerman in 1790. We’ll see how the 18th century saw the emergence of a mathematical theory of errors and estimation, paving the way for more sophisticated statistical methods.Our exploration continues into the 19th century, a period of significant growth for statistics. We’ll witness the establishment of prominent statistical societies like the Royal Statistical Society and the American Statistical Association and see how statistics became an integral part of government and social reforms.From the groundbreaking work of Florence Nightingale, who used statistics to improve healthcare practices, to the contributions of other trailblazers like Adolphe Quetelet and Francis Galton, we'll delve into the diverse applications of statistics in this transformative era.Finally, we’ll look at the 20th century and beyond, where the advent of computers revolutionised statistics, enabling the analysis of vast datasets and giving rise to new fields like data science and machine learning. Join us as we celebrate the rich history of statistics and its enduring impact on our understanding of the world.This episode aims to shed light on the development of statistics over time, providing listeners with a comprehensive understanding of the key events, figures, and concepts that have shaped this vital field.

Salam,

In this episode, i am talking about simple random sampling. 

Thanks,

Salam, 

In this episode, i am talking about the introduction to sampling techniques. There are two types of sampling techniques which are random sampling techniques and non random sampling techniques. 

In random sampling techniques, there are simple random sampling, systematic sampling, stratified sampling, cluster sampling, and multistage sampling. 

Thanks,

Salam,

In this episode, i am talking about Sampling Process. 

There are 5 process in doing sampling, started from Defining the population, establishing sampling frame, determining sample size, specifying sampling method, and selecting the sample.

Thanks,

Salam,

In this episode, i am talking about scales of measurements. 

There are 4 types of scales of measurement which are Nominal scales, Ordinal Scales, Interval Scales, and Ratio Scales. 

These scales of measurements are lies under qualitative variable and quantitative variable.
