Review of Key Quantitative Methods Issues

Q1. What is quantitative (versus a qualitative) research?

Quantitative Research Method

Qualitative Research Method

Purpose/Objective

To enumerate data and simplify collected results from a sample size to the overall population of attention

To add a considerate of fundamental motivation and research.

To determine the occurrence of various opinions and views in a selected sample

To provide approaching techniques into the situation of issues or problem, gathered ideas, views and concepts for making hypothesis that can effectual for the research study.

Sometimes it might followed by qualitative study which is use to identify some conclusion that must be wealthy for further studies

To expose widespread trends in consideration and estimation

Sample Size

Frequently a large number of cases represent the people of attention. Data of respondents has been selected randomly.

Frequently a small number of non represent or individual cases. The data of respondents has collected according to the assign quota.

Data Collection

Structured methods have used such as questionnaires, direct interviews and surveys.

Semi structured or unstructured methods such as group discussion and specific interviews

Data Analysis

Statistical techniques are use for analyzing the data. Conclusions are descriptive and decisive in nature.

Non Statistician approaches

Outcome

Used to suggest a final path of action.

Probing and investigative. Findings are not decisive and cannot be used to make simplification about the selected group of attention. Expand a preliminary considerate and sound support for additional verdict making.

The following table has effectual for describing the qualities of two research methods that have extensively used in any research study for analyzing the data (Shaver, 2005).

What determines whether a research method is good or not?

Research process is determined on the basis of facts, figures, results, applications and the tables. These are all significant factors that effectual for the investigator to evaluate whether a research method is good or not. The criteria at which the effectiveness of research design has evaluated are reliability and validity. The two significant methods, which have strictly examined the efficiency of the research process on the basis of it is obtaining results. The reliability is help to examine the measurement of errors and enlightened on its consistency. This has critically examined either the research process that has opted for any research study has produced the consistent answers or no. The consistent results have evaluated on the basis of outliers or errors that must highlight on errors. There are many types of validity that is effectual for examining the situation of the research process.

External validity

Internal validity

Construct Validity

External Validity

This validity is a type of confidence that the investigator can generalize with the findings of study, people and time which is not involved in the research study. The concerns that must occur through external validity are always present in the sample study. Suppose if the sample data has comprised of all male student, college student and all white student, then it must be doubtful indecision ...
