The study was conducted in Hawassa tabor senior secondary school, female students. Tabor senior secondary school is established in 1968 E.C .It is one of the biggest public schools in south Ethiopia. Hawassa is one of the capital city of SNNPR and 272 km far from Addis abeba. A facility based cross sectional study was conducted after stratifying students based on their class and section.
All female students of Hawassa tabor school where the source of population. Samples were selected randomly by sections from sections selected female students were selected for the study and those who have seen their menses at least three times consecutively included in the study.
The sample size was calculated by using single population proportion formula with the following parameters:-
n=minimum sample size
q=1-p=0.5, regarding this case p=50% = 0.5 and margin of error = 5% (0.05%).
P=population proportion in problem (estimated prevalence of population) =0.5
d= degree of accuracy= 0.05(margin of error)
n=(Z)2 p(1-p)
d2
n = 384.16 ≈ 384
With none respondent rate assumed to be 10%
384*10/100 =38.4≈38
n=384+38=422
nf= final sample size
N= total population= 2013
z=standard normal value at confidence interval of 95%=1.96
(Reduction formula for a population < 10,000)
So that:
nf = n / (1+n/N) = 351
Finally After stratifying the students on their class, stratified random sampling techniques was used.
