People were asked to guess how much different items weighed. The values for the guessed compared with their actual, correct values are as follows:

Guessed Correct
#1 196 159
#3 394 163
#3 350 269
#4 117 61
#5 136 76
#6 364 260
#7 74 12
#8 107 80
#9 160 88
#10 419 160

What is the correlation, and why is it so high?

Since all of the guessed weights were higher than the actual weights, does that influence the correlation at all?

Since #2 and #10 are the furthest off, remove them, and recalculate r. Explain why the direction changed the way it did.
