Chapter 3 Methodology Draft:
To determine an adequate and statistically representative sample size from the total accessible population of 1,200 undergraduate students of Delta State University, Abraka, the Taro Yamane (1967) scientific formula for finite population determination was adopted at a 5% margin of error (e = 0.05) and a 95% confidence level. The mathematical computation is illustrated below:
n = N / [ 1 + N(e)² ]
Where:
n = Required sample size
N = Total population size (1,200)
e = Margin of error allowable (0.05)
n = 1,200 / [ 1 + 1,200(0.05)² ]
n = 1,200 / [ 1 + 1,200(0.0025) ]
n = 1,200 / 4.00
n = 300 respondents.
Therefore, a sample size of 300 respondents was selected and administered structured questionnaires for the empirical investigation.
