उत्तर
This statement is false.
Explanation:
The errors that are related to the collection of data are termed Non-sampling Errors. If the field of investigation or the population size is large, then the possibility of Non-sampling Errors also increases. So, Non-sampling Errors are maximized by taking large samples.
