Statistical analysis

The response of the study participants was rated as 1= True, 2= False and 3= I do not know when the correct answer for the particular question is right: it was rated as True = 1, False =0 and I do not know = 0. Otherwise, when the correct answer is False, it was coded as True = 0, False = 0 and I do not know = 0. Frequencies, table’s percentage, mean, interquartile range (IQR) and standard deviation (S.D.) were used to describe the response of participants. Independent T-test and one way ANOVA statics were used to identify factors associated with public knowledge of CKD.
