The general feeling is that he is stupid; His general knowledge is good although he is not good at mathematics.
I'll just give you a general idea of the plan. He's trying to generalize from only two examples. In other words, how accurate are the results?
Do the results actually measure what was intended to be measured? There are several types of validity that are commonly examined and they are as follows:. There are multiple factors that can threaten the validity in a study. They can be divided into single group threats, multiple group threats, and social interaction threats. For more information, on the threats to validity click here. Reliability is defined as the consistency of the measurements. To what level will the instrument produce the same results under the same conditions every time it is used?
Reliability adds to the trustworthiness of the results because it is a testament to the methodology if the results are reproducible. The reliability is often examined by using a test and retest method where the measurement are taken twice at two different times. The reliability is critical for being able to reproduce the results, however, the validity must be confirmed first to ensure that the measurements are accurate.
Consistent measurements will only be useful if they are accurate and valid. The term falsifiability mean that any for any hypothesis to have credence, it must be possible to test whether that hypothesis may be incorrect. If a theory or hypothesis cannot be tested in such a way that may disprove it, it will likely not be considered scientific or valuable to those in the field. Generalizability refers to whether or not the research findings and conclusions that result from the study are generalizable to the larger population or other similar situations.
The ability to generalize results allows researchers to interpret and apply findings in a broader context, making the finding relevant and meaningful. Replication is the reproducibility of the study. Will the methodology produce the same results when used by different researchers studying similar subjects? Replication is important because it ensures the validity and reliability of the results and allows the results to be generalized.
If none of the commuters responded to your study, then your study is limited to the non-commuters. If a specific college is underrepresented in your study, then probably the findings may not accurately reflect that college.
If your study is a case study, you will have some in-depth findings about your case. Then you may want to show how your case can provide a good sample that represents many other similar organizations. This is a generalization issue. If your study is a qualitative study, then you assume that your findings may be true for a wider population.
Therefore, as you find the truth, you have to describe how much of this truth is applicable to the world.

Although generalizability usually applies only to certain types of quantitative methods, transferability can apply in varying degrees to most types of research. Unlike generalizability, transferability does not involve broad claims, but invites readers of research to make connections between elements of a study and their own experience.
Generalization, which is an act of reasoning that involves drawing broad inferences from particular observations, is widely-acknowledged as a quality standard in quantitative research, but is more controversial in qualitative research.

Generalization – Generalizability By admin in Methodology, Qualitative Research, Quantitative Research, Research Process December 10, The generalization is the extent to which your study is true in different settings. s use of a survey (n = 11) in their pilot study Intercultural Competency in Social Studies Education Methods was intended not for generalizability outside the sample, as is expected in quantitative research, but rather it was used as internal generalizability (Maxwell, ).
