Taking the commonly used 95% confidence level as an example, if the same population were sampled multiple times, and interval estimates made on each occasion, in approximately 95% of the cases, the true population parameter would be contained within the interval. To calculate standard deviation of sample distribution (SD/sqroot(N)), which conditions must be met?-The sample size is less than 10% of population size (N)(.10) . . The most commonly used confidence levels are 90%, 95%, and 99% which each have their own corresponding z-scores (which can be found using an equation or widely available tables like the one provided below) based on the chosen confidence level. You can also copy and paste lines of data from spreadsheets or text documents. Standard deviation is a measure of dispersion of data values about the mean. Rule of Thumb. Given that an experiment or survey is repeated many times, the confidence level essentially indicates the percentage of the time that the resulting interval found from repeated tests will contain the true result. Thus, for the case above, a sample size of at least 385 people would be necessary. c.
