You ask people to rate there depression on a scale of 1 to 10 their respnses are a (n) ___in your study. a. variable b. discrete v c. observation d. hidden v

The answer is A) variable. The depression level is a value that varies with the respondents and may inform you about the relationship between depression and other variables, such as alcohol use or sleep habits. It is also likely a discrete variable, since the answer is probably an integer (1, 2, ... 10), rather than a continuous spectrum (virtually any number between 1 and 10).
