Cochran's Sampling Technique

Cochran's Sampling Technique is a method used to determine the ideal sample size needed for accurate survey results. It considers factors like the desired confidence level (how sure you want to be), the margin of error (acceptable difference), and population variability. By inputting these, Cochran's formula helps researchers calculate a sample size that balances accuracy with efficiency, ensuring the results are representative of the entire population without collecting unnecessary data. This method is widely used in survey research to optimize resources and achieve reliable conclusions.
