Subjects of the research study should be chosen in order to meet the expectation of the other researchers, who will acquire benefit from the study. The researchers should check all the variables of the study and by applying effective strategies; they can minimize the ill effects of the characteristics of the subjects(Fraenkel & Wallen, 2009).
In order to control the threats from the data collector characteristics, the researchers should be efficient to collect the authentic data, which are considerably reliable. Therefore, for the effective execution in the authentic data collection, the effective equipment and tools should be used, which can evaluate the collected data effectively and thereby reduce the threats (Fraenkel & Wallen, 2009).
To control the regression outcome, data should be collected from reliable sources so that the research outcome is highly reliable. The regression data should be flexible enough to adapt the external changes and to prevent data manipulation that would contribute to convenient research study(Fraenkel & Wallen, 2009).
In order to control the threat from the attitude of the subjects in a research study, the researcher should select those kinds of subjects, which have positive attitudes toward the study. The subject should be capable enough to participate in the research process and support the researchers to obtainreliable outcome of the study(Fraenkel & Wallen, 2009).
Raw data and related information about the findings, which are provided in research study are collected from the reliable sources and endow with the scientific research. Research studies representing observable factsare considered true and valid(Berg &Latin, 2008).
At instances, when the research study conducted by the researcher could establish casual relationships with the study, then it can be said that the study has an internal validity. The subjects of the study are specific and the researcher ...Show more
