Algebraic expression (conceptual modeling)

Back 1

an algebraic expression in variables is an expression constructed with the variables and algebraic numbers using addition, multiplication, and rational powers.
Conceptual modeling - An abstract model (or conceptual model) is a theoretical construct that represents something, with a set of variables and a set of logical and quantitative relationships between them

Front 2

Bias

Back 2

The other source of deviation is known as the bias, or systematic error, which has to do with how the observations are made, how the instruments are set up to make the measurements, and most of all, how these observations or measurements are tallied and summarized to come up with an estimate of the true parameter

Front 3

Composite

Back 3

A composite number is a positive integer which is not prime and not equal to 1. That is, is composite if , with and natural numbers both not equal to 1.
