The most important practical difference between the two is this: Random effects are estimated with partial pooling, while fixed effects are not. Partial pooling means that, if you have few data points in a group, the group's effect estimate will be based partially on the more abundant data from other groups.An estimate is a function of a sample of data to be drawn randomly from a population whereas an estimator is the numerical value of the estimator when it is actually computed using data from a specific sample.

It is my opinion that rounding is a form of estimation, but it is far too rigid to only be rounding. Here is the official definition of rounding: If I think about estimation as a rough calculation, then I have to be much more flexible in how I think about estimating a number.

The (pretty much only) commonality shared by MLE and Bayesian estimation is their dependence on the likelihood of seen data (in our case, the 15 samples).
