Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

We discussed the fact that measuring the same thing twice (or more) often yields somewhat different results, even if the thing being
measured hasn't changed (think of measuring the size of a room, for example). That led us to suggest that
the Observed score = True score + an Error term
there is no such thing as an accurate score
the Observed score must actually equal the True score
we have to make a correction for guessing when we need to measure carefully
none of the above
