Quantitative Research Approach. ; Hover your mouse over the test name (in the Test column) to see its description. One simple measure of variability is the range, defined as the difference between the highest and lowest scores in a distribution. Research reports often require multiple tools due to the length, depth, and breadth of the report. Descriptive research uses a quantitative research method by collecting quantifiable information to be used for statistical analysis of the population sample. Quantitative research- concerned with precise measurement, replicable, controlled and used to predict events.It is a formal, objective, systematic process. Reliability RRI Relative risk increase RRR Relative risk reduction S Statistically significant SSR Single-system research ToC Table of contents Val. ; The Methodology column contains links to resources with more information about the test. Quantitative research is statistical: it has numbers attached to it, like averages, percentages or quotas. The quantity (50%) makes it quantitative research. Just as we needed a quantitative measure of centrality, so also do we require a quantitative index of variability. 60 percentage people's here represent quantitative statistical treatment of data.

This table is designed to help you choose an appropriate statistical test for data with two or more dependent variables. After the data is prepared for analysis, researchers are open to using different research and data analysis methods to derive meaningful insights. N umerical data are used to obtain information about the subject under study. Statistical Treatment of Data This study was quantitative in approach. ; Hover your mouse over the test name (in the Test column) to see its description.
