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 statistical hypothesis testing, a type I error is the incorrect rejection of a true null hypothesis (a false positive), while a type II error is the failure to reject a false null hypothesis (a false negative).he rate of the type II error is denoted by the Greek letter Î² (beta) and related to the power of a test (which equals 1âÎ²). What we actually call type I or type II error depends directly on the null hypothesis. Negation of the null hypothesis causes type I and type II errors to switch roles.
