Inferential Statistics Directed Questions

Title of article (APA format): Title of article: “Effectiveness of an Avatar application for teaching heart attack recognition and response: A pragmatic randomized control trial.” Did the descriptive statistics in the report sufficiently describe the major variables and background characteristics of the sample? Were appropriate descriptive statistics used—e.g., was a mean presented when percentages would have been more informative? Yes, the descriptive statistics provided valuable information about the variables and background characteristics of the study such as age, sex, diagnosis, educational level, and comorbidities. The mean values and standard deviations were used appropriately for age and BMI. Also, the study did use percentage were necessary, such as for diagnosis type. Did the researchers report any inferential statistics? The researchers reported Chi-square tests to provide evidence for the effectiveness of the study to see if there is a relationship between the two variables. Were the selected statistical tests appropriate? What kind of test was used? Yes, the selected stat tests were appropriate for the type of study design and data that was provided. The tests used were the Tobit growth curve model, independent t-tests, Chi-square tests, and binary logistic regression tests. Were the results of any statistical tests significant? The results for the p-value showed significance that the Avatar application improved knowledge, attitudes, and beliefs at the one and six month follow ups. In addition, there was significance in the between-group differences which showed p < 0.05 for the heart attack plan and ambulance use. Lastly, the logistic regression that was performed showed significance in improvement of education level and age.
