Range of Error |
|
Two reasons for considering larger samples:
1) When small changes must be measured (e.g. political polls, awareness tracking). 2) When sub-groups must be analyzed (e.g. men vs women, customers vs non). |
|
A Range of Error at the .95 Confidence Limit means: If a study were repeated 100 times, 95 of the results would be within the range of error. |
