• Demonstrate how to use the margin of error formula (z*• S ) to calculate sample size when given a predetermined margin of error and level of confidence for a one-proportion z-interval
• Review standard error for proportions.
This packet shows you the method to find the minimum required sample size when you are already given a margin of error and confidence level. We show you several examples of calculating sample sizes, and review what the standard error for proportions is.
This packet covers sample size estimation for a proportion, given a margin of error and confidence level. There are no new terms in this packet.
This powerpoint shows you the two methods for calculating sample sizes based on predetermined margins of error.
This video shows how to find a desired sample size for a proportion.
