A 150 - 300 word response to the following question:

In a simple regression analysis, you notice that the R2 value is low (less than 0.4); however, the standard error is low. What does this tell you about the analysis? Conversely in another analysis, you notice that the R2 value is high (greater than 0.8) but that the standard error is also high. What does this tell you about the analysis?
