The effect of caffeine on taste is tested by randomly giving one sample of participants regular soda and another sample is given decaffeinated soda.

A) Dependent samples

B) Independent samples

The correct answer is A. Both samples are dependent samples.

Step-by-step explanation:

Both samples are dependent samples, since to verify the effects of one, it is necessary to compare it with the effects and characteristics of the other.

Thus, in the case, it is intended to check the effects of caffeine on taste by using a regular soda sample first, and then comparing it with a decaffeinated soda sample. Therefore, the effects of one sample will be checked and compared with the other sample, so that there is a dependency relationship between the two, since neither could prove the hypothesis on its own.
