Slovin's Formula

 $n=\frac{N}{\left(1+Ne^2\right)}$              where: n = sample size

                                            N = population size

                                            e = margin of error

Multiple Choice

What does "n" represent in the formula?

• population size

• sample size

• margin of error

Multiple Choice

What does "e" represent in the formula?

• population size

• sample size

• margin of error

Multiple Choice

What does "N" represent in the formula?

• population size

• sample size

• margin of error

Determine the sample size for the given population size and margin of error.

1.N = 1000; e = 5%

2.N = 2000; e = 2%

3.N = 3000; e = 8%

4.N = 10 000; e = 6%

5.N = 15 000; e = 9%

Determine the sample size for the given population size and margin of error.

1. N = 1000; e = 5%
