The difference between the observed and the true value is the error.
The most probable value depends on how it is defined and calculated. The maximum likelihood estimate (MLE) is often used but there are situations where it is not the most probable.
For example, you are in a town where the bus routes are numbered sequentially. You want to know how many routes there are and so you observe the route numbers on a sample of buses. The MLE is the largest number that you observe but, in reality, there is no mechanism that will ensure that the bus with the largest route number is in your sample.
It is the observed error.

Empirical anything is what is observed. Theoretical is a calculation of what things ought to be.
estimation is to think of an answer before measuring the quantity and approximation is to round off.
The difference between actual quantity and standard quantity is called the material quantity variance.
It is the observed error.
The treatment effect is the difference between the observed outcome and the "normal" outcome

An inventory variance report shows the difference between previous recorded inventory quantity and correct inventory quantity which is discovered immediately after a physical count. It also reports on the value difference the quantity variances caused.
Quantity is how much of something that you have. Quality is how long something lasts or how "good" it is.
