presented as a public service of Creative Research Systems survey software. You can use it to determine how many people you need to interview in order to get results that reflect the target http://www.mathcelebrity.com/search.php?q=margin%20of%20error%20for%201%2C9 population as precisely as needed. You can also find the level of precision you have in an existing sample. Before using the sample size calculator, there are two terms that you need to know. These are: confidence interval and confidence level. If you are not familiar with these terms, click here. To learn more about the factors that affect the size of confidence intervals, click here. Enter http://www.surveysystem.com/sscalc.htm your choices in a calculator below to find the sample size you need or the confidence interval you have. Leave the Population box blank, if the population is very large or unknown.

For example, if you use a confidence interval of 4 and 47% percent of your sample picks an answer you can be "sure" that if you had asked the question of the entire relevant population between 43% (47-4) and 51% (47+4) would have picked that answer. The confidence level tells you how sure you can be. It is expressed as a percentage and represents how often the true percentage of the population who would pick an answer lies within the confidence interval. The 95% confidence level means you can be 95% certain; the 99% confidence level means you can be 99% certain. Most researchers use the 95% con

In statistics & probability, the larger & lower ME provides lower & higher confidence intervals. Margin of margin of error Error & its Formula It's a widespread abstract of sampling error, which measures an uncertainty about an experiment or test result. Generally, margin of error (ME) is 1.96 times of Standard Error. The standard error calculation can be done by the mathematical formula SE = (√((p(1-p)/n) )). Therefore ME = 1.96 x √((p(1-p)/n) ). 1.96 is the z-score for 95% confidence (commonly used), 1.64 is the z-score for 90% confidence level and 2.58 is the z-score for 99% confidence level. Margin of error arises whenever a population is incompletely sampled. The higher value provides lower confidence interval & the lower value provides higher confidence interval. The below mathematical formula is used in this calculator to determine the uncertainty of an experiment result based on the input values of sample size n, probability p & population size N.
