Answer to question no. 1
In the article, the author reported that the method of the study was based on blinded
randomization. The randomization is used to minimize the bias of an investigation. A survey can
be double-blind, single-blind or open. Here, the author used blind randomization, where they
assigned patients using a computer-generated sequence and a hidden envelope according to the
ratio of usual care and multimedia educational involvement (Saturni, et al., 2014). The study also
revealed that the data were analyzed with the help of statistical methods like Pearson’s Chi-
square test and student’s t-test in the initial stage of care procedure to identify the true
randomization. In this paper, the author analyzed the data of Dutch Heart Failure Knowledge
Scale and Self-Care of Heart Failure Index by the methods of distribution free tests since these
constant variables did not encounter the hypothesis of Kolmogorov-Smirnov test normality. Non-
parametric criteria are followed in the situation when the data does not support any specific
distribution, and no assumptions can be made from there. Hence, there can be an increased
chance of the data analysis biasness that would affect the probable outcome and prevent from
getting the relevant result of this study. In this article, another possible biasness is the data
analyst should not be informed previously about the selection of the participant.
Answer to question number 2
The research has shown that the researchers measured the samples as random, and the
result has showcased that personalized, software educational interference has decreased all-cause
unplanned hospital readmissions of a patient with Heart Failure at 12 months. In this article, the
