It proved a complex process to eliminate variables that were related to intelligence without removing any that might be directly related to lead.
Elimination theory, the theory of the methods to eliminate variables between polynomial equations.
This test can also help eliminate any issues or variables to employers about who may need further training and instruction or not.
In general, keeping the two cells separate is preferable from the point of view of eliminating variables from an experiment.
The simplest method for solving a system of linear equations is to repeatedly eliminate variables.
In the worst case it is presumably hard to eliminate variables computationally.
The more experimental control we have, the easier it is to eliminate confounding variables, and better causal conclusions can be made.
Experimenters try to eliminate confounding variables as much as possible.
Experiments that eliminate variables are called control experiments.
Wind tunnels also eliminate other variables that can affect results, such as bumps in the road or inclement weather.
