This requires adherence to the principle of random sampling to avoid researcher’s bias in interpreting the results that defeat the purpose of research. This requires a large population, the numbers of which depend on how the characteristics of the population vary.

Assume a Normal Population Distributionįor more reliable data analysis of quantitative data, a normal population distribution curve is preferred over a non-normal distribution. It makes sure that respondents provide the expected answers or satisfies the intent of the researcher to meet the research objectives. Pre-testing helps identify areas in the research instruments that need revisions. Standardized, pre-tested instruments guide data collection thus ensuring the accuracy, reliability and validity of data. The data collection instruments include questionnaires, polls, or surveys. Quantitative research method use measuring devices like the caliper. These measurable characteristics are referred to as the variables of the study such as age, the number of children, educational status, and economic status. Contain Measurable Variablesĭata gathering instruments contain items that solicit measurable characteristics of the population. The characteristics of quantitative research methods are enumerated in the following list. Seven characteristics discriminate qualitative methods of research from qualitative ones. 7 Characteristics of Quantitative Research Methods The output serves as the basis for making the conclusions and generalizations of the study.

These numbers will then be analyzed using the appropriate statistical application software to unravel significant relationships or differences between variables. pH, dissolved oxygen, salinity, turbidity, and conductivity to measure water quality). Such surveys use instruments that require numerical inputs or direct measurements of parameters that characterize the subject of investigation (e.g. The data that will serve as the basis for explaining a phenomenon, therefore, can be gathered through surveys. Four types of measurement scale exist namely nominal, ordinal, ratio, and interval (see 4 Statistical Scales of Measurement). The numbers used in statistical analysis originate from objective scales of measurement of the units of analysis called variables. It emphasizes numerical data analysis using computational techniques. Quantitative research methods are those research methods that use numbers as its basis for making generalizations about a phenomenon. Pizarro has already described qualitative research in this site, so this article focuses on quantitative methods, its meaning and characteristics. Or, a quantitative study may identify research areas that require the application of qualitative methods to provide an in-depth understanding of the phenomenon at hand or when the use of quantitative methods is insufficient to answer questions that relate to human behavior such as feelings, values, and beliefs. Qualitative methods may be used to explore a phenomenon and identify factors for a quantitative study. Recently, many researchers use both methods, thereby the era of using mixed methods in research arose as a more desirable and encompassing approach in understanding phenomena.

Some research topics are better studied using quantitative methods while others are more appropriately explored using qualitative methods. The decision to select the method largely depends on the researcher’s judgment as well as the nature of the research topic. The methods used by researchers may either be quantitative or qualitative.
