The main aim of this unit is to introduce you to the basic concepts used in descriptive statistics and elementary probability theory such as:- measures of central tendency, measures of dispersion, skewness and kurtosis, random variables, probability, conditional probability and univariate probability distributions.

Statistics refers to the collection, organizing, presentation, analyzing, and interpretation of numerical data to make inferences and reach decisions in all branches of economics, business, medicine, and other social and physical sciences.

Probability And Statistics are the two important concepts in Maths. Probability is all about chance. Whereas statistics is more about how we handle various data using different techniques. It helps to represent complicated data in a very easy and understandable way.

Social statistics is the use of statistical measurement tools to study human/social behavior in a social environment. This can be accomplished through drawing a particular group of people, evaluating a particular subset of data obtained about a group of people, or by observation and statistical analysis of a set of data that relates to people and their behaviours. Social scientists use social statistics for many purposes, which include: 1) the evaluation of the quality of services provided to a specific group or by a certain organization, 2) analyzing behaviors of groups of people in their environment and special situations, and 3) determining the wants or needs of people through statistical sampling

Health – is the complete state of physical, mental and social well being and not merely the absence of disease or infirmity. Statistics – the word statistics has two meanings. First in the common usage statistics refers to numerical facts. Second it is a scientific field of study dealing with collection, organizing, summarizing, analyzing, presenting of data and as well as drawing valid conclusion (interpretation) and making reasonable decision on the basis of such analysis.

Social statistics is the use of statistical measurement systems to study human behavior in a social environment. This is mainly done through sampling a particular group of people, evaluating a particular subset of data obtained about a group of people, or by observation and statistical analysis of a set of data that relates to people and their behaviors.

This is an introductory Section to statistics, which provides the definition and types of statistics. It also gives the purpose of statistical analyses, especially the meaning of statistical significance in geography. It demonstrates that even proper use of statistics does not guarantee useful results. Other important aspects introduced in this Section are a number of new terms, concepts and symbols that are used quite often in statistics.

Health statistics Statistics is the mathematical science involving the collection, analysis and interpretation of data. It’s the methodology for collecting, analyzing, interpreting and drawing conclusions from information. Statistics provides methods for 1. Design: Planning and carrying out research studies. 2. Description: Summarizing and exploring data. 3. Inference: Making predictions and generalizing about phenomena represented by the data.
