a. Critical Thinking Critical Thinking Suppose you and a friend each take different random samples of data pairs (x,y) from the sample population. Assume the samples are the same size. Based on your samples, you compute r= 0.83. Based on her sample, your friend computes r = 0.79. Is your friend’s value for r wrong? Explain?

As I said before, it would depend on the size of the samples to see if the difference was significant. Based on three pairs, it probably would not be significant. Based on 1000 pairs, the difference probably would be significant.

It does not make a different value right or wrong.
