Building a handrail for your deck may seem like a simple task. In many cases it is -- until the time arrives to figure out how to get the balusters or spindles evenly spaced along the handrail.

R-squared is a statistical measurement that determines the proportion of a security's return, or the return on a specific portfolio of securities, that can be explained by variations in the stock market, as measured by a benchmark index.
The adjusted R-squared is a modified version of R-squared for the number of predictors in a model. The adjusted R-squared can be negative, but isn't always, while an R-squared value is between zero and 100 and shows the linear relationship in the sample of data even when there is no basic relationship.The adjusted R-squared is the best estimate of the degree of relationship in the basic population.y Investopedia AAA |. A: One major difference between R-squared and the adjusted R-squared is that R-squared supposes that every independent variable in the model explains the variation in the dependent variable.
