Experimental Groups are used to compare the effects of an intervention (treatment) in one population to the effects in another. For example, one might be interested in the question of whether there are differences between the memories of people diagnosed as dyslexic and "non-dyslexic" people.
Also, if subjects are randomly assigned to groups, as in "true experiments," then effects observed in the groups will be statistically independent among groups, thereby making it easier to interpret the specific effects of different treatments and controls.
In an experimental design like this hypothetical animation study, the experimental groups are referred to as "treatment groups" and "control groups." In this study, the treatment group is presented a computer animated video depiction of the alleged crime in a jury trial. The control group does not see the video animation.
In an important sense, "no treatment" is also an event because something is always going on between measurements. To demarcate the time period involved, we will insert a "Null Event" in the Control Group at the location corresponding to the location of the treatment in the Treatment Group.

When is theoretical less than the experimental?
theoretical probability can be smaller than expiremental like this say you toss a coin 4 times it lands on head 3 times that means the theoretical 1/2 is now smaller than the expiremental 3/4
Who was one of the first scientist to use numbers to look for patterns in expiremental data?
screw you i ain't tellin!!
What is the relationship between experimental and theoretical probability?
expiremental: finding the answer by observing it lots of times.. theoretical: its like a theory,, you just guess!!~ <3

How are experimental bias and emotional bias alike and different?
Alike:They are both an error that distort results in a particular way.Different: Emotional bias is distortion in cognition and decision making and expiremental bias is error that distorts results in a particular way.
