Quantitative Article Critique

Quantitative Article Critique This study consisted of quantitative research because it used precise measurements to obtain data that were statistically analyzed. The purpose of the study, Model of functional performance in obese elderly people with chronic obstructive pulmonary disease by Dr. Jochebed Bosede Ade-Oshifogun (2012), was to test the relationships among percent truncal obesity; disease severity; dyspnea; functional capacity; and functional performance of elderly people with chronic obstructive pulmonary disease (COPD).

Reliability coefficients were calculated for all variables in the path model, and they met or exceeded minimal levels (Ade-Oshifogun, 2012). All research information was scrutinized for any missing data. All data were subjected to univariate analysis of variance (Ade-Oshifogun, 2012). Path analysis with multiple linear regressions was utilized to test the relationships among the study variables (Ade-Oshifogun, 2012). The techniques utilized were appropriate for this study as they accurately verified that the data were valid and …show more content…
This allowed for more thorough and precise measurements of all the involved factors. Another strength was that this was possibly “the first study to incorporate body composition as a variable into a functional performance model” (Ade-Oshifogun, 2012, p.238). A major limitation was that the severely and morbidly obese were not included in the study due to the weight limit of the DEXA scanner (Ade-Oshifogun, 2012).. This caused two major groups to be excluded and no pertinent data was obtained. Another limitation was that the study group was English-speaking only, which did not allow for potential regional differences (Ade-Oshifogun,

    Weight Bias

    The article titled “Parents and Vehicle Purchases for Their Children: A Surprising Source of Weight Bias” was published in 2010, and showcases the research efforts of authors Amanda Kraha and Adriel Boals. The purpose of the study, as explained in the article, seeks to build or add on to previous findings that detail the fact that individuals considered overweight are more likely than their slimmer counterparts to rely on their own sources of income to fund their education rather than by family, and more broadly with any other large expenditures. The authors have hypothesized that this trend observed by previous findings will carry on more specifically to car-buying expenses. The results of the study conclude and suggest that overweight individuals discernibly will most reasonably place reliance on themselves and their own sources of income to fund the expenditure of a car, this also being the case after controlling for socioeconomic differences. Where the article succeeds: Of the aspects of the study that present its findings in a very empirical manner, one that stands out is its very well accounted for possibility for an impetuous and heedless demeanor in individuals being the sensible conclusion that results in overweight people lacking any aid…

    The Relationship Between Age And Respiratory Flow Rate In Biruwa

    Introduction Residents in Biruwa may experience the absence of flu serum, due to limited quantities at the start of winter. Some facilities on various islands suggest the elder population, potentially the most susceptible, should receive priority. However, facilities specifically from Biruwa want those largely threatened by breathing difficulties to obtain the injection before others. Investigators are studying whether older islanders acquire more breathing difficulties caused by having a weakened lung capacity. Also, investigators are studying if age alone has an impact on lung capacity.…
