A parameter in an experiment that can change is known as a variable.
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)
A fire science investigator is a investigator who try to find out why the fire started
Yes, if the experiment does not produce the same results time and time again
Yes, there is a variable that can be manipulated by the investigator. What that variable is depends on what the investigator is investigating and the variables that are available.
what is the working conditions for a forensic investigator
The investigator changes the independent variable in an experiment to observe its effect on the dependent variable.
The factor that is manipulated by the investigator in a psychological experiment is called the independent variable. It is the variable that the researcher changes or controls to see how it affects the dependent variable.

A homicide investigator's pay varies widely depending what jurisdiction they serve or what agency employs them and how long they've been doing the job.
the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.

The variable that the investigator changes or manipulates during the experiment is called the independent variable. This is the factor that is deliberately altered in order to observe its effect on the dependent variable, which is the outcome being measured.
in a manipulative experiment the investigator has control over the variables in the experiment. a natural experiment is simply making observations of naturally occurring events and looking for correlations between phenomena. Natural experiments are primarily just measuring and analyzing statistics.
The dependent variable varies due to effects of the factor being tested in a controlled experiment.
It varies widely depending on the area of the country and who the CSI is employed by.
