Detailed explanation-1: -error introduced by a lack of precision in conducting the study. defined in terms of the null hypothesis, which is no difference between the intervention group and the control group. reduced by meticulous technique and by large sample size.
Detailed explanation-2: -A sampling error is a statistical error that occurs when an analyst does not select a sample that represents the entire population of data. As a result, the results found in the sample do not represent the results that would be obtained from the entire population.
Detailed explanation-3: -Type I error (false positive): the test result says you have coronavirus, but you actually don’t. Type II error (false negative): the test result says you don’t have coronavirus, but you actually do.
Detailed explanation-4: -A type I error occurs if a true null hypothesis is rejected (a “false positive”), while a type II error occurs if a false null hypothesis is not rejected (a “false negative”). In other words, a type I error is detecting an effect that is not present, while a type II error is failing to detect an effect that is present.
