82C refers to the average of all covariance between items V refers to the average variance of each item The questionnaires were given to 40 selected form four students (boys and girls who were later excluded from theactual study). For this study a coefficient rate of r = .70 or above was deemed adequate. Table 3.4 shows theCronbach's alpha coefficient indicators obtained after test analysis.

The researcher used the research permit to seek for official permission from the County Director of Education, Busia County and County commissioner to carry out research in secondary schools in the county. Besides, the researcher wrote a self- introductory letter to the principals of schools selected for the study to request for permission and cooperation during the research activity.
