One of the principles this research methodology falls into is Replicability, which states that findings must be capable of being replicated following the same research method. We can only be certain in a claim if it has been tested in numerous different ways and all of them conclude the same result. In the article it mentions that Dr. Zoosk and his colleagues have replicated the findings from the PDR at their clinic in two different conclusions. This research methodology does a good job practicing the replicability principle since results must to be duplicated when following the same method. Dr.Zoosk had adequate evidence to support his claim. To be confident in a …show more content…
It was a sampling bias since it is not representative of the overall population. Sampling bias means the sample does not represent the features of the general population. The participants in this study were 250 Caucasian adults between the ages 18-35. This methodology has purposeful selection by the Dr.Zoosk and his colleague. Selection bias can lead a study to result in a controlled result from what you would have gotten if you selected the entire target population. There was selection bias on the race which was chosen for this particular study, as well as the age groups were also limited to 18-35, which doesn’t give much dependability on the study. If there was variations of age and race within the sample population being observed, the study might of shown a completely different outcome. Bias in the study leads to unrepresentative outcomes. To fix this, select a random sample that has relevant features of the target, even though you don’t always know which features will turn out to be
