Quantitative methods are advantageous because they allow researchers to conduct a broad survey, which involves many subjects and generalization of findings. They also yield accurate results. On the other hand, quantitative methods are rigid and provide less detail on the motivation, attitudes and behavior of study subjects.Know More
Quantitative methods are standardized, making them effective in comparing research findings with similar studies. Additionally, they allow researchers to summarize vast sources of data. Quantitative methods are reliable and valid because they employ prescribed procedures. They also eliminate bias in a study because they involve many cases and few variables, which prevent researchers from using subjects known to them. Quantitative methods enable researchers to correlate independent and dependent variables in order to determine causality within a study framework. Furthermore, these methods allow researchers to control the data collection environment so that extraneous variables are not introduced into a study.
On the other hand, the University of Southern California notes that the use of standardized questions in quantitative research may cause structural bias. In fact, research findings may reflect the view of the researcher rather than those of the respondent. The findings of quantitative research methods are numerical and therefore lack a detailed narrative of human perception. The respondents may also provide answers that reflect their preconceived hypotheses. About.com notes that the generation and testing of hypotheses in quantitative research methods can be subjective and misleading. Structured instruments such as questionnaires are used to gather quantitative data.Learn more in Statistics
Coaxial cables are advantageous because they support multiple channels and have a high bandwidth and low error rates. However, they are disadvantageous because they are susceptible to security risks, damage, congestion and noise, and they are costly to install.Full Answer >
Antibiotics are advantageous because they combat infections preserve lives and do not harm normal body cells, but they are disadvantageous because they have side effects and can kill healthy bacteria. About.com also notes that harmful microorganisms, such as Staphylococcus aureus, can develop a resistance to antibiotics. Bacteria develop resistance through gene mutation, which alters their cell walls.Full Answer >
During participant observation, which is used in social science studies, the researchers actively become part of the group being investigated. This first-hand, embedded method of collecting information often leads to copious, rich data. However, researchers have opportunities to interfere with the process, and this has the potential to skew results.Full Answer >
Inferential statistics is a branch of statistics that can be used when researchers and mathematicians want to attempt to extrapolate on and reach conclusions that extend beyond the raw data itself. While a study only uses a small sample of the total population it is studying, inferential statistics can be used to attempt to estimate traits and thought patterns of behavior among the population as a whole.Full Answer >
