Inferential Statistical Analysis

Soaring Crane

The basis of inferential (testing) statistical analysis is that data are composed of two elements,

a. theoretical expectation + error
b. mean + standard error

Would the two correct elements be listed in choice a.?

The mean of a sample and the standard error (which is the sample’s standard deviation?) is more descriptive than inferential (testing), right? (Or did I completely confuse the terms?)

Thank you.

Where did you get such theory?
