Article Analysis - Assignment Example That is, verbal and video. The findings indicate a variability in the two groups subjected to the different tools. The changes are observed as more in the verbal category. A change in preference of 29% in the verbal group compared to 6% in the video category communicates a significant underlying factor in the use of the two treatments. Also worth noting, however insignificant, is the percentage of the persons who were uncertain in the two cases. 3% for verbal against 1% for video. A significant difference is evident. Given the nature of the trial, and since according to the researchers it was the first of its kind, it breeds an inquiry into the subject (p. 6). It is noted that a narrative description alone may not be very useful. Alternatively, most of the participants were positive about video description. Despite the highlighted limitation of the study, the findings of the study present the use of video decision support tool as superior to the narrative description(pp. 6-7). The study used a randomized valid sample (n=200). Out of which, the researchers subjected two groups to different treatments and the outcomes noted. Also, the study does not indicate any previous similar treatment or behavior among the participants. The participants are selected and exposed to the different treatments, and the effects of such treatments are observed. Moreover, the investigators express control over the treatments to their participants making them more of â€Å"experimental units†. The investigators assign the treatments, and they have control. All the noted features makes the study an experiment. The study used various types of statistical analyses including Standard deviation, Pearson Chi-square test, 2 sample t-test, K statistics, bivariate analysis, Fisher’s exact test and Multivariable logistic regression analyses at 0.05 level. This paper discusses the Pearson Chi-square test, bivariate analysis and regression analyses. (1)
