That is, the experimenter randomly assigned students to the two groups. Random assignment is a powerful tool though it does nothing to decrease the amount of error that occurs as a result of extraneous variables, in only equalizes it between groups.
I work at ASDA (days) but my other half used to work nights. Its over Â£8 an hr and working nights everyone becomes a real community as there aren't really many customers about so you can have a laugh.y dream job at the moment is to work at ASDA preferably at George. ASDA is one of the best places around with products that represent a great value for money. They also sell great chocolate/cookies. Best supermarket chain around by a clear mile.
Extra pay for working night shifts is a matter of agreement between the employer and the employee (or the employee's representative). The Fair Labor Standards Act (FLSA) does not require extra pay for night work. However, the FLSA does require that covered, nonexempt workers be paid not less than time and one-half the employee's regular rate for time worked over 40 hours in a workweek.
