To numerically demonstrate the formula of the exact bias, a popular data set published in a journal of statistics education is revisited, and we quantify why the conclusion of data analysis can be different before and after accounting for the precursor variable. The result shall remind the ...
In statistics, there is one more measure for estimating the variability in data -standard error of mean, which is sometimes shortened (though, incorrectly) to just "standard error". The standard deviation and standard error of the mean are two closely related concepts, but not the same. While...

When data in a dataset is missing, we may use imputation to fill the gaps. For substitution, common methods include the use of mean or median. It's essential to be cautious while using the imputation technique as it can introduce bias and affect the results. When deciding on the optimal ...

scores is 70%, all of the other test scores are below it. So, this is a very useful way to determine exactly where within a data set a certain value falls, and can minimize the effects of bias in the data set, such as exam scores for an exam which was too difficult for everyone....

Systematic sampling is used because it is a very simple and convenient way of forming a sample population that is free from favoritism or bias. There is also no need to number each member of the sample. The procedure for completing the sampling process is fast and easy. How do you do a...
