The effect of caffeine as an ingredient is tested with a sample of regular soda and another sample with decaffeinated soda. Is the sample matched pairs or independent samples?
The accuracy of verbal responses is tested in an experiment in which individuals report their heights and then are measured. The data consist of the reported height and measured height for each individual. Is the sample independent samples or matched pairs?
I am still confused with the definition and difference between independent samples and matched pairs. I would think that the first question is independent samples and the second one is matched pairs.????

The first example is matched pairs, while the second is independent samples.
Here's a general rule: if pairing must be maintained in the sample, they're matched pairs, and if the samples can be rearranged without affecting the experiment, they're independent samples.
So in your soda experiment, if you randomized all the soda and drew random pairs of two sodas (that is to say, one pair could be both caffeinated, both decaffeinated, or one caffeinated and the other decaffeinated) the experiment wouldn't be the same as the intended experiment. Therefore, it's matched pairs.
In the second experiment, about the verbal accuracy of reported heights, is the experiment going to change if you ask person A before person B? No, so it's an independent sample.
Best of luck.

The matched pairs experiment always produces a larger test statistic than the independent-samples experiment.
true or false?
