The correlation between and would likely be the highest. a. shyness averaged over a month; shyness on a given day b. shyness averaged over a month; shyness averaged over a week c. shyness averaged over a month; shyness averaged over a different month d. shyness on a given day; shyness on another day

The correlations would likely be highest with scenario (c). When taking two averages over different months, the values should have some resemblance to each other. In addition, since the values are both measuring the same time periods, there will be an ability to see a pattern with the two.

The advantage of administering personality tests on employees is that it will allow the employer to know the mindset and personality of the employee. this will allow the employer to at least have an idea as to how the employee works and how his attitude in the workplace. the disadvantage is that it may make the employee a little anxious as to whether he would meet the personality requirements of the employer and whether he would be able to retain the job or not.
