Since there is a fault in the data collection, the results obtained from sampling become invalid. Furthermore, when a sample is selected randomly, or the selection is based on bias, it fails to denote the whole population, and sampling errors will certainly occur. They can be prevented if t...
Discuss the differences between sampling and nonsampling error. Explain what can be done to reduce both when using a sample. Describe the risks that could occur when sampling error is high or nonsampling error is not considered. PROVIDE A ...

The procedure also did not guarantee random sampling within each prefecture, and thus our estimations used standard errors that were robust at the prefecture-level. We additionally introduce Japan's situation regarding COVID-19 and vaccines. As of March 16, when we started this experiment, the ...
While correcting errors is usually valid, correcting only the errors that lead to unwelcome results is not. Plausible justifications can also be found for deleting certain data points, though again, only doing this to the unwelcome ones is invalid. All of these effectively introduce sampling bias ...
The two classes (high and low risk) are not well-balanced for the two waves. For this reason, we use SMOTE43 (Synthetic Minority Over-sampling Technique), a commonly adopted technique to rebalance the problem. We have found the best performance in terms of downstream classification task for ...
1 The survey used quota sampling such that the sample is representative in terms of age and gender for North Rhine-Westphalia, the most populous of Germany's federal states.2 The survey encompassed multiple sections, starting with respondents providing information on standard demographics such as ...
