Which data collection method would provide an unbiased sample?

a.)
Emailing a questionnaire to the employees
b.)
Asking all employees who work from 8am - 5pm
c.)
Posting a request for survey volunteers in the company's breakroom
d.)
Asking five random employees from each shift

Answers

The data collection method that would provide an unbiased sample is "asking five random employees from each shift"

An unbiased sample is a sample whereby all the individuals have and equal chance of being picked for the research study.

In this case, asking five random employees from each shift is an unbiased sampling as everyone has an equal chance of being picked.

Option A is incorrect. Emailing a questionnaire to all the employees will be costly and isn't sampling.

Option B is incorrect. Asking all employees who work from 8am - 5pm is bias as others that doesn't work within the time frame aren't taken into consideration.

Option C is incorrect. Posting a request for the survey volunteers that are in the company's breakroom is biased.

Therefore, the correct option is D.

THIS IS AN ECONOMICS QUESTION

When economists and policy makers talk about full employment, they do not mean 100 percent employment, rather they mean reaching a certain point that still leaves a portion of the labor force unemployed. Why is this the case and what are the kinds of unemployment that exist that do not allow us to reach 100 percent employment?

Answers

Employment cannot reach 100 percent because there is always unemployment. The kinds of unemployment that do not allow 100 percent employment are frictional, structural, cyclical and seasonal unemployment
