New cards
Correlation [r]
The linear association between y(context) and x(context) is __ strength and __ direction
2
New cards
Residual
The actual y(context) was Residual above/below the predicted value when x(context) = __
3
New cards
Slope
The predicted y(context) increases/decreases by slope for each additional x(context)
4
New cards
Coefficient of Determination [r²]
About r²% of the variation in y(context) can be explained by the linear relationship with x(context)
5
New cards
Standard Deviation of Residuals [s]
The actual y(context) is typically about s away from the value predicted by the LSRL with x(context)
6
New cards
Y-Int
The predicted y(context) when x = 0 context is y-int
