contribution of statisticians in the development of Statistics

[Audio] Statistics is an ever evolving field with a long history. Several world renowned statisticians have made huge contributions to its development, including data classification and inference research, and the development of sophisticated probability theories and models. Their work has allowed the field of Statistics to make tremendous progress. Without it, Statistics would not be where it is today..

[Audio] For centuries, Statistics has been employed by illustrious minds. Carl Friedrich Gauss, Pierre-Simon Laplace, John Maynard Keynes, and Alfred Marshall are among the many distinguished individuals to have dedicated their energy and resources to unlocking the potential of Statistics. As a result, Statistics has become one of the fundamental branches of mathematics and progressed at a remarkable speed. Their remarkable contributions have allowed us to benefit immensely from Statistics in today's world, allowing us to analyze, connect, and understand sets of data both big and small. We owe it to their invaluable contributions that we are now able to take advantage of Statistics in the manner we do today..

[Audio] Statistics is a field with a long and rich history, stretching back centuries and featuring contributions from many famous statisticians from around the world. It is divided into two main areas: descriptive and inferential. Descriptive statistics uses measures such as mean, variance, skewness, and kurtosis to assess the properties of sample and population data. Inferential statistics applies these properties to draw conclusions and test hypotheses, using techniques like linear regression analysis, ANOVA, logit/Probit models, and null hypothesis testing..

[Audio] Statistics is a subject which has evolved over many centuries owing to the efforts of several mathematicians and statisticians. Notable figures like Pierre-Simon Laplace and Carl Friedrich Gauss, along with the less renowned Gertrude Cox, have all contributed to its growth. Descriptive statistics is a branch which aims to provide an overview of a given sample data set with the help of numerical values such as mean, median, range, variance and standard deviation..

[Audio] Inferential Statistics allow for the examination of characteristics of a population, based on a data sample. These measurements include central tendency, variability, distribution, and correlations within the data. With these, statisticians can calculate the probability of a statistic accurately describing the parameter of the whole population. In this way, accurate conclusions can be drawn from the data..

[Audio] Mean, median and mode are used to describe elements of central tendency in a given group of data. To calculate the mean, add the numbers of the data set and divide by the number of observations. Median is the middle number in a set of data. The mode is the number between the highest and lowest values and it appears most often in the data set..

[Audio] Statistics has been an integral part of society and the field has been developed by many famous statisticians throughout the centuries. Fred Kerley, the American runner who placed 2nd in the 100-meter sprint in the 2020 Tokyo Olympic Games, provides an example of how Statistics is used to measure outcomes at an ordinal-level. As opposed to assigning numerical or quantitative values, this method simply arranges results in an order. This is just one of the many ways Statistics has helped us to gain insights into the world around us..

[Audio] Statistics provides us with essential information to make decisions and interpret the world around us. It has been shaped by renowned statisticians from many countries, with their contributions giving us access to understanding that we would not have been able to gain otherwise. This presentation has illustrated the breadth of Statistics and its practical application in daily life. Thank you for tuning in..
