An adequate knowledge of statistics is necessary for proper designing of an epidemiological study or a clinical trial. This requires a proper design of the study, an appropriate selection of the study sample and choice of a suitable statistical test. Statistics is a branch of science that deals with the collection, organisation, analysis of data and drawing of inferences from the samples to the whole Key words: Basic statistical tools, degree of dispersion, measures of central tendency, parametric tests and non-parametric tests, variables, variance Parametric and non-parametric tests used for data analysis. An idea of the sample size estimation, power analysis and the statistical errors is given. The article covers a brief outline of the variables, an understanding of quantitative and qualitative variables and the measures of central tendency. This article will try to acquaint the reader with the basic research tools that are utilised while conducting various studies. The results and inferences are precise only if proper statistical tests are used. The statistical analysis gives meaning to the meaningless numbers, thereby breathing life into a Statistical methods involved in carrying out a study include planning, designing, collecting data, analysing, drawing meaningful interpretation and reporting of the research findings.

Researcher to make presumptive conclusions about the population of interest, however, as this is reserved for more advanced, inferential statistics.ĭescriptive statistics provide information along two main dimensions: measures of central tendency and measures of spread. Moreover, descriptive statistics determine which advanced statistical tests are appropriate. A data set, which contains hundreds or thousands of individual data points or observations, for example, can be condensed into a series of statistics that provide useful information on the population of interest. As such, descriptive statistics serve as a starting point for data analysis, allowing researchers to organize, simplify, and summarize data.
