Sample size calculator is a statistical tool for calculating the size of the sample in a population. This calculation is difficult if the sample size is very high. Sample size determination is an essential one in the case of a statistical survey. Using the below formula we can calculate the size of a sample. It is given by,

## Problems on Sample Size Calculator

1. ### The values of Z,p and C are given as 1.96, 0.1 and 0.03 respectively. Find the size of the sample of the population?

Step 1 :

The given parameters are

Z=1.96, p=0.1 and C=0.03

Step 2 :

n=1.962 $\times$ $\frac{0.1(1-0.1)}{0.03^{2}}$

n=3.8416$\times$ $\frac{0.1\times 0.9}{0.0009}$

n=$\frac{0.345744}{0.0009}$=384.16≈384

n=384

2. ### Determine the sample size when Z=1.96, p=0.3, c=0.04?

Step 1 :

The given values are

Z=1.96, p=0.3, c=0.04

Step 2 :

n=1.962$\times$ $\frac{0.3(1-0.3)}{0.04^{2}}$

n=3.8416$\times$ $\frac{0.3\times 0.7}{0.0016}$

n = $\frac{0.806736}{0.0016}$ = 504.21≈504
