What Sample Size Do I Need To Be Statistically Significant. In a population of 200000 10 would. It is generally accepted that power should be8 or greater.
Generally the rule of thumb is that the larger the sample size the more statistically significant it ismeaning theres less of a chance that your results happened by coincidence. Expressed as a percentage the typical value is 95 or 095. The smaller the percentage the larger your sample size will need to be.
It is generally accepted that power should be8 or greater.
For a test with 005 and 010 the minimum sample size required for the test is More often we must compute the sample size with the population standard deviation being unknown The procedures for computing sample sizes when the standard deviation is not known are similar to but more complex than when the standard deviation is known. Heres what it looks like when you open it up. For example in a population of 5000 10 would be 500. Dummies helps everyone be more knowledgeable and confident in applying what they know.
