CHAPTER THREE
METHODOLOGY
3.1 Introduction
In this chapter, the methodology of the study will be examined. It will comprise the procedure and strategies that was employed in the conduct of this research. The sub headings include the research design, population, sample and sampling techniques, research instrument, reliability of the instrument, validity of the instrument and procedure for data collection and data analysis.
3.2 Research Design
For the purpose of this study, survey research design was adopted. This research design is mainly aimed at testing the formulated hypotheses with the necessary and appropriate test statistics. Descriptive statistics was used to summarise the sample and inferential statistics was employed to learn about the population of the sample
3.3 Population and Sample Size of the Study
The population of this study comprise all secondary schools operating in Ilorin South Local Government Area of Kwara State. However, for simplicity, five (5) schools only in the local government area were selected as the sample frame for the study.
3.4 Sampling Technique
This study adopted stratified and simple random sampling technique. Stratified sampling was used such that 20 questionnaires were administered to each school making 100 questionnaires in all. Then in each school, the 20 questionnaires were random administered to parents in the school.
3.6 Research Instrument
For the purpose of this study, primary data was employed through the administration of well-structured questionnaire. Use of questionnaire for survey research is the best instrument for collecting data because as surveys are carried out in natural settings, questionnaire increases the external validity of the study (Bowling, 1999).
3.7 Validity of Instrument
Validity is one of the important attribute of a test instrument and it is the degree to which a test measure what it supposed to measure. Validity is the degree to which any measurement approach or instrument succeeds in describing or quantifying what it is designed to measure. To establish the validity of the test instrument (questionnaire), copy of the questionnaire were given to panel of experts in the Department of Health Promotion and Environmental Health Education University of Ilorin so as to scrutinize, correct, authenticate and guarantee validity of the questions (item) of the questionnaire before administration is done. The corrections made by the experts were effected on the final copies of the questionnaire that were administered.
3.8 Administration of the Questionnaire
After the validity and reliability of the questionnaire have been determined, the questionnaires were administered among the selected sample for the study. The researcher personally administered the questionnaires to the respondents.
3.9 Method of Data Analysis
Data analysis forms the bedrock of any research work. To make data analysis meaningful, it must focus on testing research hypothesis so as to enable the researcher determine whether to accept or reject the hypothesis formulated for the study. The data obtained from the field of the study was presented using descriptive statistic of simple percentage. For inferential statistical analysis of the data gathered, Analysis of Variance (ANOVA) employed to test the stated hypotheses.
ANOVA is mathematically expressed as;
Mstr= Mean of the squares of treatment
SStr= Sum of the squares of treatment
SSe= Sum of the squared error
K= Degree of freedom
Sn= Number of responses
