In order to establish a statistical correlation between a and E, we need to compare two groups that are basically the same, except that a is present in one and not present in the other.Given that the individual members of these groups might vary quite a lot, how can we make it likely that, apart from the presence of a, the two groups are basically the same?

A) Use large, randomly chosen groups.
B) Use very small, randomly chosen groups.
C) The only way is to put exactly the same individual members into both groups.
D) The only way is to match each individual in the first group with an individual that has all of the same characteristics in the second group.
E) The two groups can never be similar enough to provide any meaningful information about whether or not there is a correlation.

Large

Of considerable or relatively great size, extent, capacity, or quantity.

Randomly Chosen Groups

Groups formed without any predetermined pattern, often used in experimental designs to ensure objectivity.
