Answer to Question 1

SUPPOSE YOU WERE COMPARING MEN'S HEIGHTS TO WOMEN'S HEIGHTS. IF ALL THE MEN WERE THE SAME HEIGHT, AND ALL THE WOMEN WERE THE SAME HEIGHT, THE ONLY DIFFERENCE IN HEIGHT WOULD BE DUE TO GENDER. BUT BECAUSE OF NATURAL VARIABILITY FROM MAN TO MAN, AND FROM WOMAN TO WOMAN, THIS MAKES IT HARDER TO CLEARLY SEE DIFFERENCES IN HEIGHT BETWEEN MEN AND WOMEN.

Answer to Question 2

THE AMOUNT BY WHICH A MEASUREMENT DIFFERS FROM THE TRUE VALUE.
