3.4 Sample Size Determination
The sample size for the study was determined using Taro Yamane’s method.
The formula is given below:
n = N
1 + N (e2)
Where:
n = Sample size
N = Population (700)
e = Sampling error (0.5)
1 = Constant (given)
By Substitution
n = 700
1+700 (0.052)
n = 254.54
n = 254

Sampling Plan
The researcher adopted a probability sampling method for the study. Here
all the elements of the sample were given equal chance of been selected.
However, Taro Yemene’s method will be adopted.
