Scenario:According to some research, males have better spatial skills than do females; and according to other research, females have better reading skills than males. A student is interested in determining which gender performs better on a word-search puzzle (a puzzle in which words are hidden vertically, horizontally, and diagonally within an array of letters) since this type of puzzle involves both spatial and reading skills. A sample of males and females volunteer to participate and are given 10 minutes to work on a 50-word puzzle.The number of words correctly recognized is recorded for each subject. Use this scenario to answer the following questions.

What is the independent variable? Dependent variable? What is the scale of measurement for each?
