Data analysis
Statistical Package for Social Sciences (SPSS) version 22 was used to evaluate the data obtained from the participants. Statistical significance level was accepted as p <0.05. Student t-test and Mann Whitney-U test were used for the comparison of the continous variables on the basis of their distribution. Chi-square test was used for the comparison of the categorical data and shown as frequencies. The Pearson’s rank correlation tests were performed to determine the relationships between continuous variables for parametric and nonparametric datas, respectively. Regression analysis was used to clarify the impact of Type D personality on PMS.
