A study was conducted with the objective of determining the effect of two different strength-training programs, one involving the use of a balance ball and the other using stationary exercise equipment, on blood pressure and cholesterol levels in women over the age of 60. Eighty women over the age of 60 were identified and randomly divided into two equal-sized experimental groups. Each member of the two groups was trained and allowed to follow the prescribed routine for 8 weeks. The subjects were aware of the purpose of the study but not that there were two different treatment groups involved. The cholesterol levels and blood pressure for subjects were measured at the start and at the end of the 8 weeks. The experimenter and the medical technician were not told to which group any of the subjects were assigned. This is an example of an attempt to conduct
