Q.Emergency department workers are notified that researchers will be conducting research on worker efficiency. As a result, the workers are subject to:

The Hawthorne effect

Selection bias

Lack of generalizability

Heterogeneous

A.The hawthrone effect:

It is the behaviour of the worker or the response of the worker that changes during the period of research because they have already notified about the research and they may be know that they are watching their work.so it may effects in the result.

B.Selection bias:

Selection bias is occur due to the selection process due to the reaesrch was going to do in the emergency workers it may leads to systematic errors when it is compared with the population.

C.Lack of generalizability:

It lacks the generalizability because the research is going to be conducting  in the emergency workers so the efficiency of workers will be seen in only emergency department only so the results of the study will be applicable only for the specific population group so it results in poor generalizability.

D.Heterogeneous:

The heteroginity of the workers will be different from each other the elements of the individual are differ from each other for example age ,income,work,race,religion that may effects the results/outcome of the study.
