.** the squaring is done so negative values do not cancel positive values. the smaller the mean squared error, the closer the fit is to the data. the mse has the units squared of whatever is plotted on the vertical axis. another quantity that we calculate is the root mean squared error...

is Newton and it is expressed in the fundamental units. The unit of force is $kg m {s^{-2}}.$ Note:Another method to find the unit of force is,Force = mass(acceleration)Unit of the mass is kilogram and acceleration is meter per second squared.Force= $kg m ...
What does that mean? It means, that there is no real number such that squaring it leads to a negative output. That is what we mean when we say that \(\sqrt {-4}\) is not real, which means that there is no real number \(b\) with the property that \(b^2 = -4\). ...
