Quantitative analysis - Research topic ExampleHistory confound defines events that occur during the data collection process to influence the dependent variant without effects from independent variable. The events may increase effects of the independent variable or reduce them and thence compromises validity of data. Maturation confound however defines transitions in research participants cognitive or physical properties towards contrastive precept by the same person. A longitudinal fill may involve change in age that associates with mendd rationale and physical characteristics that may change an individuals perception. Other factors much(prenominal) as education, stress, and physical strain may also influence a persons rationale into different perspectives during a study. Test confound is a nonher challenge to denary research and defines differences in results because of a research participants previous experience with the test instrument and the experience influences result s from values that would be observed on first encounter with the same test. Interactive effect is another threat to quantitative research and defines association amidst two or more confounds in a study. Interaction amongst treatment and narration is an example results in different values from actual effects of a studys independent variables (LoBiondo & Haber, 2013). Challenges of quantitative research are evident and offer a basis for differentiating betwixt quantitative and soft research. Their understanding are therefore important, not only for development and implementation of qualitative research initiatives, but also for understanding differences between the two research methods in order to cover development of a suitable research methodology for a study (Allwood, 2012). History confound is a signifi croupet threat to quantitative research because of its potential to alter results in a study. History can occur in a studys internal or external environment and this defines the utmost to which it may be significant to a study. In a study to investigate effects of lecturers expression on effectiveness of learning process, an independent forum on learning skills that averts students attention from a lecturers appearance is an external historic factor to the study. A seminar to lecturers on how to improve their lecturers is however, an external historical factor and both offer significant potential to shifting the relationship between lectures appearance and effectiveness of lecturers. The extent of such an impact on results further depends on effectiveness of the history factor. The challenge is based on factors beyond rationale of research participants and therefore defines independence from bias, unless the history event is selective to influence a proportion of research participants and their associated data. In the absence of bias, history has supply impacts on phenomenon of study and therefore ensures reliability of collected data because of a possible uniform shift in relationships. Consistency in measures will therefore be attained in a historically confounded study but validity will be compromised because of lost accuracy on the effects of independent variables on the subject dependent variable. Possible existence of reliability but not validity in a data
