Answer:
Population and Sample Size: The population in this case would be all the Technical Universities in Ghana. To calculate the sample size, Mr. Anyanful could use the formula for sample size calculation:
n = N / (1 + N(e^2)) Where: n = sample size N = population size e = margin of error (usually set at 5% or 0.05)
The technique to choose the sample size could be simple random sampling or stratified sampling. Simple random sampling involves selecting a sample purely by chance, while stratified sampling involves dividing the population into subgroups and then taking a random sample from each subgroup. The choice of technique would depend on the resources available and the specific objectives of the study.
Investigation Method and Data Collection Tool: A suitable method to carry out the investigation could be a combination of quantitative and qualitative research methods. This could involve using surveys/questionnaires to gather quantitative data on procurement processes, compliance, and value for money. Additionally, interviews or focus group discussions could be conducted to gather qualitative data on the challenges and underlying reasons for non-compliance.
The data collection tool for the quantitative aspect could be a structured questionnaire with closed-ended questions to measure compliance levels and value for money. For the qualitative aspect, semi-structured interviews or focus group discussions could be used to gather in-depth insights from procurement officers, senior management, and other relevant stakeholders.
Data analysis for the quantitative data could involve statistical analysis using software like SPSS or Excel to identify patterns, correlations, and compliance levels. For the qualitative data, thematic analysis could be used to identify recurring themes and insights from the interviews or focus group discussions.
