Effect n dependent variable pain Show linear association/ Graph arrangement
Example Anxiety Nausea Temperature Blood pressure

Effect n dependent variable pain Show linear association/ Graph arrangement

Explanation / Answer

A linear relationship can be described in the following way:

Let X1= Anxiety level, X2 = Nausea (Present/absent), X3 = Temperature, X4 = Blood pressure,

Y : Pain level,

Y = b1*X1 + b2*X2 + b3*X3 + b4*X4,

where, b1, b2, b3 , b4 are the linear regression coefficients to be estimated using Least squares method.
