experiment
The term for that is algebra.
Are term whose variables are the same
These terms are called like terms.For example: x and 2x are like terms.But: x3 and 4x2 are not like termsbecause although the variables are the same, the exponents are different.
They are "like" terms.
It is a term involving two variables, x and y.
It is called a "term".
Sample Statistics
experiment
The term for that is algebra.
It is called a term.
It is called a constant term. It is number only and contains no variables
The definition to the term "Stochastic Process" is: A statistical process involving a number of random variables depending on a number variable. Which in most cases, is time.
A constant term.
A value separated from the rest of the data is called an outlier
The term data means groups of information that represent the qualitative or quantitative attributes of a variable or set of variables. Data (plural of datum, which is seldom used) are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and knowledge are derived. So no they cannot be used interchangeably.
I don't know if there is an official term, but I have only heard it called: Plug n' chug. This is because you "plug" in numbers into the variables, and then "chug" through the computations to get the answer.
