- Statistical Analysis
For this purpose, the researcher made use of both descriptive and inferential statistics. The first statistical procedure conducted a series of descriptive data analyses on the results of the questionnaires consisting of measuring mean, median, standard deviation, standard error of the mean, variance, minimum, maximum, sum of teachers‘teaching styles and so forth, NLP and autonomy scores of the participants. In addition, skewness ratio and kurtosis ratio were calculated to check the normality of distribution. Moreover, teaching styles’ frequencies along with normality of distribution of variables were calculated.
Taking the inferential statistics into account, to examine the relationships among teachers’ five teaching styles, NLP, and autonomy, owing to having one nominal and one interval variable and the non-normality of data, non-parametric Kruskal Wallis and Mann Whitney tests were utilized. Furthermore, in terms of the third hypothesis, owing to the non-normality of data, Spearman’s rho was employed. Regression analysis was performed so as to verify the power of predictor variables’ prediction towards autonomy as the predicted variable. Furthermore, the reliability of the instruments were estimated utilizing Cronbach’s alpha coefficient.
