IUI requires ovulation, at least one open fallopian tube, and a semen sample with healthy sperm. Each IUI treatment is referred to as a cycle â the time from the first day of your period to ovulation and insemination and then a pregnancy test two weeks later.
Total survey error - Sources of nonsampling error. 1  The survey literature decomposes nonsampling errors into five general sources or types: specification error, frame error, nonresponse error, measurement error, and processing error. Specification error occurs when the concept implied by the survey question differs from the concept meant to be measured in the survey.
In statistics, a relative standard error, or RSE, is equal to the standard error of a survey estimate divided by the survey estimate and then multiplied by 100.he standard deviation of a data set is used to express the concentration of survey results. Less variety in the data results in a lower standard deviation. More variety is likely to result in a higher standard deviation. The standard error is sometimes confused with standard deviation.
