Why do scientists use two different models of light?
To distinguish results based on the only two variables of awareness. Observed (presence) vs the unobserved (absence) changes the outcome in every experiment. Something like a control group, if i am on the right side of the road (as in 50 states, but not territories of the US that is us.
How many variables may be tested legitimately in any one experiment?
I think it's very difficult to answer this question simply. Depending on the sophistication of your research model and the amount of data and the accuracy with which the research is carried out, you can test several variables simultaneously. This can be done 'legitimately', and sometimes it is too costly to run research projects that test one or two variables at a time. Some of these complex and sophisticated statistical models are used very infrequently, but it can be done.
Three kinds of models used in science?
mathematical models conceptual models and Physical models
Is anything from models fake?
Not necessarily. Models for faith, models for morals and conduct, and models for leadership are, for examples, not fake.
What are the three major types of explanatory models?
regression models econometric models leading indicators
How many variables do you investigate in a controlled experiment?
There are complex models that allow researchers to study several variables if the experiment is carefully designed and very carefully carried out. These models can show whether a variety of variable interactions occur, and if that is your focus then these models are good. But the best experiments investigate a small number of variables, as few as one.
What is one drawback of using models to represent scientific processes?
Models may not take into account all of the variables.
Definition for decision models and decision variables?
Decision variables are the variables within a model that one can control. They are not random variables. For example, a decision variable might be: whether to vaccinate a population (TRUE or FALSE); the amount of budget to spend (a continuous variable between some minimum and maximum); or how many cars to have in a car pool (a discrete variable between some minimum and maximum).
What are econometric models?
Econometric models are causal models that statistically identify the relationships between variables and how changes in one or more variables cause changes in another variable.
Why are animal studies or animal models run?
To learn more about animals.
How do structural models work?
Structural models of the economy try to capture the interrelationships among many variables, using statistical analysis to estimate the historic patterns.
What is the similarity between computer models and physical models?
They are both models, andthey both can be explained.

What secondary type of data is used in econometric models?
Economic forecasting models predominantly use time-series data, where the values of the variables change over time.

How have mathematics and technology changed the way scientist create models?
i think this is the answer but anyway... Scientist can create models from large amounts of data from many different variables. if this is not correct i will check it on Fridaytomorrow.
