DATA ANALYSIS
A marking scheme was formulated for the questionnaire and marks were allocated to each person participated
o Best acceptable answer - 2 marks.
o Next best answer - 1 mark.
o Unacceptable answer - 0 marks.
Marks obtained plotted against number of students
o Range = 9 - 16
o Mean = 14.01
o Mode = 15
o Median = 14
o Standard deviation = 1.685
Marks plotted against Male and Female student samples
o Male
Mean = 14.52
Standard deviation = 1.22
o Female
Mean = 13.64
Standard deviation = 1.86
o Next using statistical methods we inquired whether the observed difference among male and female was statistically significant or just due to chance.
o A null hypothesis was formed
There is no difference between the male and the female samples regarding mean value obtained in the questionnaire, on healthy practices in food and water consumption
Z= X1 – X2
s1² + s2²
n1 n2
Z = 2.8701
Chi square test were applied to certain aspects of the study
o Null hypothesis-
there is no difference between male and female students on the practice of washing hands with soap and water before each meal
o Chi square value obtained = 0.2151
o 0.05 confidence interval = 3.84
o Null hypothesis
–There is no significant difference between male and female students in consumption of boiled water for drinking purposes
o Chi square value obtained = 0.326
o 0.05 confidence interval value for a 3×2 contingency table = 5.99
