Theprimary aspects that make the conduction of experimental studies ineducation more challenging is propensity matching. Other factors thatalso contribute to the challenge include assigning of subjects in arandom manner to the treatment and control conditions and accountingfor carryover effects. Other aspects entail application of the properstatistical tests and data analysis (Lee, 2013).

Propensitymatching is essential for selecting near same participants based onselect variables because no individual is identical to another (Lee,2013). However, it has been noted that it is not always possible, orpractical to assign subjects in educational environments. Theimpossibility is attributed to the schedule constraints, regulatoryrequirements, and parent/student unwillingness to consent, andresistance from the instructor/administrator. For example, it mighttake long for a researcher to reach many parents to acquire theirconsent to involve their children in a study.

Carryovereffects obtained from a better performance which results frompractice or poor performance attributed to fatigue can unpredictablyhave an effect on results (Kalafatis &amp Ledden, 2013). Theoutcomes can, however, be altered on condition that the researchapplies a counterbalance or order technique. Taken together, thesefactors can adversely affect reliability, validity, transferability,and generalizability of results. A study is considered applicable inother similar settings if its credibility and validity are certified(Peterson &amp Merunka, 2014). The size of the sample and themethods used to reach the outcomes contribute to the generalizabilityof a study.

Theimplication of these factors on my research design is minimal. I willbe conducting a quantitative methodology and non-experimentalcorrelation design. Thus, the aforementioned primary factorapplicable to my study is applying the appropriate primary dataanalysis and statistical tests. Another related research utilizedmultivariate correlation analysis and Pearson correlation statisticaltests.
