Skip to main content. Strengths Weaknesses Study findings can be generalized to the population about which information is required. Samples of individuals, communities, or organizations can be selected to ensure that the results will be representative of the population studied.
Structural factors that determine how inequalities such as gender inequalities are produced can be analyzed. QUANT estimates can be obtained of the magnitude and distribution of impacts. QUANT estimates can be obtained of the costs and benefits of interventions. Clear documentation can be provided regarding the content and application of the survey instruments so that other researchers can assess the validity of the findings.
Standardized approaches permit the study to be replicated in different areas or over time with the production of comparable findings. It is possible to control for the effects of extraneous variables that might result in misleading interpretations of causality although this can be challenging in the natural settings of evaluations.
Many kinds of information are difficult to obtain through structured data collection instruments, particularly on sensitive topics such as domestic violence or income. Many groups such as sex workers, drug users, illegal immigrants, squatters and ethnic minorities are always difficult to reach, but the problems are often greater for QUANT data collection methods.
Self-reported information obtained from questionnaires may be inaccurate or incomplete. For example, a researcher using qualitative research may conduct in-depth interviews, interact with participants and rely on her own observations. A researcher using quantitative research methods remains separated from the subject matter.
The researcher remains objective when conducting research. Instead of conducting in-depth interviews, a researcher may use analysis and questionnaires to test a hypothesis. An advantage of using quantitative research is that the researcher remains more objective while proving or disproving a hypothesis. Quantitative and qualitative research both encompass planning before conducting or analyzing research. Quantitative research, however, involves more planning, which becomes a disadvantage.
For instance all aspects of a research study must be carefully designed before collecting any data. A researcher needs a concrete hypothesis and needs to know the type of research involvedsuch as questionnaires and test questions.
With qualitative research, the design typically emerges as the research study develops. Quantitative research depends on data and involves testing a hypothesis, but it can miss contextual details. For example, a researcher doesn't provide a detailed description when using quantitative research. Instead the researcher depends on numbers and statistics to prove a hypothesis.
A researcher researching diabetes medication, for instance, might record how many times a research participant missed the medication but not the details of what happened during a participant's day to cause him to forget to take the diabetes medication. Demetrius Sewell is an experienced journalist who, since , has been a contributing writer to such websites as Internet Brands and print publications such as "Cinci Pulse.
She has a master's degree in English.
Annex 1: Strengths and weaknesses of quantitative evaluation designs. Strengths. Weaknesses. Research methods are inflexible because the instruments cannot be modified once the study begins. Reduction of data to numbers results in lost information.
Strengths and limitations; etc. are often included in quantitative research. Quantitative data is analysed using statistical methods. Quantitative approaches are best used to answer what, when and who questions and are not well suited to how and why questions. Strengths.

Evaluation among the strengths and weaknesses of quantitative and qualitative research methodologies also the objective for this study in the field of social science. The Strengths and Weaknesses of Research Methodology: Comparison and Complimentary between.
When researching a topic such as television trends or diabetes medications, a researcher has two research methods to choose from: qualitative and quantitative. Qualitative research relies on words to explain research findings; it may use interviews or focus groups. Quantitative research involves creating a hypothesis. Strengths and Weaknesses of Quantitative and Qualitative Research. Insights from Research behavior patterns, and use cases. Each of these approaches has strengths and weaknesses, and each can benefit from our combining them with one another. While quantitative research requires the standardization of data collection to allow .
