A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
To eliminate the influence of uncontrolled variables during experimentation
Only the one being tested
do separate experiments
yes
true
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.

establish a control group identical to the experimental group except for the variable being tested
Controlled -time, temperature, location, age at start.
Controlled observations involve manipulating variables and controlling conditions to observe specific effects, while uncontrolled observations involve observing natural events as they occur without intervention. Controlled observations are often used in experiments to test hypotheses, while uncontrolled observations are more common in naturalistic studies where researchers aim to understand behaviors in their natural context.
Too many uncontrolled variables to predict. Probably will not influence price, but for individual hybrid owners cost might decline.
That crash was just another uncontrolled landing.
