This is pretty important stuff. I wish you were looking through your instructional materials for discussion of "correlation" instead of just asking for answers here.
r = 0.92 indicates a strong, positive correlation.
correlation (r) can be anywhere from-1 to +1.
r -0.17 indicates a weak negative correlation.
True, r = 0.1 means that there's no significant correlation.
Correlation is a numeric meausre of the strength and the direction between two NUMERIC variables.
