Is a higher or lower root mean squared error better?
A lower.
What is a high percent error mean?
high percent error is the absolute value of something that is multiplied
How do you calculate mean squared error?
The Mean Squared Error (MSE) is a measure of how close a fitted line is to data points. For every data point, you take the distance vertically from the point to the corresponding y value on the curve fit, this is known as the error, and square the value. Next you add up all those values for all data points, and divide by the number of points. The reason for squaring is 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.
What does a high standard error mean?
It means theres a high amount of variation between the results used to calculate the mean value for a particular sample or experiment
Is it better to have a high or low mean absolute deviation?

Pie squared plus pie squared divied by 2?
if you mean PI squared + PI squared / by 2 then that is.... 4.9298 solved on paper ... BUT if you mean what you said, the answer is YUMMY!
What does this mean n squared by 3?
n^3 mean a number Squared by 3
What does MAD refer to?
It refers to Mean Absolute Deviation. It is the sum of errors divided by the sample size. It can be used in evaluating the accuracy of demand forecasting method by summing the differences between the actual demand and the forecast demand then dividing by the sample size. It is more convenient to use than the other method of evaluating the accuracy of forecasting method, which is Mean Squared Error (MSE). MSE is calculated by taken the sum of squared errors divided by the sample size. MSE uses the squared errors, which can enlarge the error values unnecessarily.
What is e x squared?
If you mean ex squared, the answer is e2x
What is a squared x a squared?
If you mean a2 x a2... the answer is a4
Why do you use average percentage error and why is it better than mean error?
Percentage error shows how wrong an answer can be with respect to the value of the answer itself. So, we can see how serious the errors are. For example, lets say we have an answer whose mean error is 40. If nothing is given of the actual value of the answer, we cannot determine if this error is insignificant or very serious. If the actual answer was 40000, this mean error of 40 is quite insignificant as the percentage error is 40/40000 x 100 = 0.1 % 0.1 % error is quite insignificant. Mean error, on the other hand, does not help us to determine the significance of this error in any way.
