Overview of Quantitative Research Methods

Quantitative Research Approach

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.

Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques. Quantitative research focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon. Babbie, Earl R. The Practice of Social Research. Your goal in conducting quantitative research study is to determine the relationship between one thing [an independent variable] and another [a dependent or outcome variable] within a population. Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment]. A descriptive study establishes only associations between variables; an experimental study establishes causality.

Quantitative research most often uses deductive logic, in which researchers start with hypotheses and then collect data which can be used to determine whether empirical evidence to support that hypothesis exists. Quantitative analysis requires numeric information in the form of variables. A variable is a way of measuring any characteristic that varies or has two or more possible values. Many characteristics are naturally numeric in nature such as years of education, age, income ; for these numeric variables, the numbers used to measure the characteristic are meaningful in that they measure the amount of that characteristic that is present. Often researchers are interested in characteristics which are not numeric in nature such as gender, race, religiosity , but even these variables are assigned numeric values for use in quantitative analysis although these numbers do not measure the amount of the characteristic present. Variables can thus be divided into numeric variables in which the numbers have meaning and categorical variables which are commonly words or ranges. Quantitative data can be collected in a variety of ways.
