Question

Hypersexual behavior caused by traumatic brain injury (TBI) is often treated with the drug Depo-Provera. In a clinical study, 8 young males with TBI had their testosterone levels measured before the study, and weekly subsequently for a period of 6 months, for a total of 48 observations. The data obtained should be analyzed using

(a) Independent sample techniques

(b) Dependent sample techniques

Answer 1

it is a case of dependent sample techniques

because we can see that the testosterone levels measured before the study and then after testosterone levels measured.

So, same set of 8 young males are used for before and after reading, this means that we are using same person to take two different data set.

We know that when we use same data item for two different data reading or measuremen, then we say that we have dependent samples.

Therefore, option B is correct answer

it is not independent samples because we are not using two different set of young adults. If we use two set of young adults and then take measurement, then only we can say that we have an independent sample case.
