Statistical analysis
The data was analyzed using statistical package for social science
(SPSS) version 21. 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.
