Document Summary
What is the pay gap: difference in the amount of money earned between two groups. One that we are concerned with is the gap between men and women in the work force. To nd the pay gap: divide women"s medial earnings by men"s medial earnings to nd the earnings ratio, to nd pay gap, subtract women"s median earnings from men"s and then divide that sum by men"s median earnings. What is the causal claim to be tested in this situation: being a woman causes you to get paid less, x = being a women, y= being paid less. How do we set up a controlled experiment to test that claim: retrospective or prospective study, would need to nd people with similar . What should we do about the pay gap: if maternity is a contributing factor, that might be a place to start.
