Data for: A Quality Analysis of Disc Herniation Videos on YouTube
Description
Descriptive data were used to define continuous variables (mean, standard deviation, minimum, median, maximum). Comparisons of two independent and normally distributed continuous variables were performed with the Student t test. Comparisons of two independent and non-normally distributed continuous variables were performed with the Mann Whitney U test. Spearman’s rho coefficient was calculated to evaluate the correlation between two non-normally distributed continuous variables. Cronbach’s alpha coefficient was calculated to determine the consistency between two continuous measurements. A linear regression analysis was performed to examine the effects of independent variables on continuous dependent variables. The statistically significant level was set at 0.05, and the statistical analysis was performed using MedCale Software version 12.7.7 (MedCale Software bvba, Ostend, Belgium; http://www.medcalc.orf; 2013).
