Look at the following research article to see how the statistical techniques you have already learned are used in practice:

Watson, J., Kinstler, A., Vidonish III, W. P., Wagner, M., Li, L., Davis, K. G., . . . Daraiseh, N. M. (2015). Impact of noise on nurses in pediatric intensive care units. American Journal of Critical Care, 24(5), 377–384. doi:10.4037/ajcc2015260

The sample was found to reflect the same gender and age distribution of the population of inpatient nurses within this facility. What does this mean about the representativeness of the sample for this facility? Of a national population of nurses from all inpatient facilities? How does this affect the generalizability of the study results?
