# Hi! What's a great R squared value?

#1
Today we had a protein assay experiment and we need to make a graph and calculate the R Squared value. We will get graded on how good that value is.

I got a 0.9722...will a get a high percentage grade based on that R squared value? Or shall I resit the practical to try and get a higher R Squared value?

As far as I know anything over 0.9 is classed as a good R squared. But somebody else may say otherwise okay.

In other fields, the standards for a good R-Squared reading can be much higher, such as 0.9 or above. In finance, an R-Squared above 0.7 would generally be seen as showing a high level of correlation, whereas a measure below 0.4 would show a low correlation.......
