How does one eliminate the influence of uncontrolled variables during experimentation?
do separate experiments
To eliminate the influence of uncontrolled variables during experimentation?
establish a control group identical to the experimental group except for the variable being tested
What is an example of operational variables?
If no-one offers you a satisfactory answer to this question you might try asking it again specifying a context. This term may be used in manufacturing, it may be used in experimentation. It might be used in other contexts too.
3 types of variables?
controlled,manipulated,responding variables
Define and differentiate between endogenous and exogenous variables?
The endogenous variables value is established by the conditions of the other variables in the structure. The exogenous variables value in independent of the conditions of the other variables in the structure. The difference between the endogenous and exogenous variables is the endogenous depends solely on the structure and the exogenous depend on outside elements.

What are variables and uncontrolled variables?
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
How many uncontrolled variables can be in a experiment?
Only the one being tested
Would prices of gasoline increase if everyone used hybrid cars?
Too many uncontrolled variables to predict. Probably will not influence price, but for individual hybrid owners cost might decline.
Is a hypothesis developed by determining a way to test multiple uncontrolled variables?
yes
Is this true A hypothesis is developed by determining a way to test multiple uncontrolled variables?
true
To eliminate the possibility of hidden or unknown variables the scientist must run what kind of experiment?
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.
How can you eliminate confounding variables in your experiment?
To eliminate confounding variables, or variables that were not controlled and damaged the validity of the experiment by affecting the dependent and independent variable, the experimenter should plan ahead. They should run many checks before actually running an experiment.
What variables did you have to control in order to get a valid result?
We controlled the independent variable (the variable we manipulated) to observe its effect on the dependent variable (the variable we measured). We also controlled for any potential confounding variables that could influence the results. Additionally, we ensured consistency in experimental conditions to eliminate any extraneous variables that could impact the outcome.
Why should psychologists question the results of an experiment that they conducted for the first time?
Experimentation enables the investigator to control the situation and to decrease the possibility that unnoticed, outside variables will influence the results. From Understanding Psychology Teacher Wraparound Edition, Hardcover (2008)
Why do you need a controlled experiment?
In order to conclusively prove or disprove something. i.e an uncontrolled experiment will have so many variables that nothing can be conclusively proven from it, since it could be argued that the outcome could have been caused by any of the uncontrolled variables. Whereas by controlling some of the variables, the ability to prove that one variable links to a certain outcome is easier to establish.
