Question

Knowing that you need a sample pool of 1019 students to ultimately get about 500 students in your sample, you are in a position to draw a systematic sample from the student directory at your university. Further, 9,500 students are listed in the directory. What is the sampling interval? Interpret your results.Show all your work.

Answer 1

Sampling interval = 9.323

Explanation:

Given that:

Population size, N = 9500

Require sample, n = 1019

Sampling interval :

Population size / required sample size

Sampling interval = 9500 / 1019 = 9.3228

Interpretation :

In other to obtain a sample of 1019 drawn systematically from the population, a sample will be drawn at every 9.323 units from the population of 9500
