My Math Forum Regression Analysis of Survey Data

The value 1 represents "strongly disagrees" and 10 represents "strongly agrees". When i perform linear regression, the coefficient of the resulting line is 0.8. I interpret this as a dependence between the two sets. Questions: 1. Previously i have only performed regression analysis using continuous data, therefore I am a bit uncertain if what I am doing is OK - basically I am treating the discrete data as if it were continuous data. Is that OK? 2. I also want to use the regression as a predictor. E.g. given a new x value in the set X, I want to predict the associated y variable. However, since i use simple regression analysis the new y-value can attain a continuous value (e.g. 5.4) which is clearly not a valid value. Should i round this value down to 5?
