Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom composing a crystal". Statistics deals with every aspect of data, including the planning of data collection in terms of the design of surveys and experiments. When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey samples. Representative sampling assures that inferences and conclusions can reasonably extend from the sample to the population as a whole. An experimental study involves taking measurements of the system under study, manipulating the system, and then taking additional measurements using the same procedure to determine if the manipulation has modified the values of the measurements.

Statistical Methods And Calculation Skills Isabel Willemse , Peter Nyelisani As with its predecessors, this fourth edition of Statistical Methods and Calculation Skills aims to equip students with the skills to apply statistical analysis and quantitative techniques in the research and working environments, and to make effective decisions. Part A: — statistical methods — covers the collection and presentation of data; descriptive and inferential methods of analysis; index numbers; regression and correlation analysis; time series; probability and probability distributions; statistical estimation; and hypothesis testing. Part B: Calculation skills are revised in Part B, which deals with elementary calculations such as exponents, decimals, scientific notation, logarithms and rounding.

Statistical methods involved in carrying out a study include planning, designing, collecting data, analysing, drawing meaningful interpretation and reporting of the research findings. The statistical analysis gives meaning to the meaningless numbers, thereby breathing life into a lifeless data. The results and inferences are precise only if proper statistical tests are used. This article will try to acquaint the reader with the basic research tools that are utilised while conducting various studies. The article covers a brief outline of the variables, an understanding of quantitative and qualitative variables and the measures of central tendency. An idea of the sample size estimation, power analysis and the statistical errors is given. Finally, there is a summary of parametric and non-parametric tests used for data analysis.
