Who receives treatment in an experimental study?
Participants in an experimental study receive the treatment. Typically, participants are randomly assigned to either the treatment group, which receives the experimental treatment, or the control group, which does not receive the treatment or receives a standard treatment for comparison.
Being randomly assigned to the experimental condition in a research project involves being assigned?
Being randomly assigned to the experimental condition in a research project involves being assigned to a group by chance. This is aimed at generating the best possible results of a research.

to the group in which participants are representative of people in general.

True
Is randomization in an experiment means that the experimental units or subjects have been assigned to their respective test groups randomly?
yes, it is.
What does random assignment ensure?
Random assignment ensures that participants in an experiment have an equal chance of being assigned to different experimental conditions. This helps to control for potential biases and ensures that any differences in outcomes can be attributed to the treatment being tested rather than other factors.
What is expiremental group?
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. by: Rosnelric C.

What is scientific bias and how do you avoid it?
There are numerous biases (e.g., knowing which subjects are assigned to which experimental groups). Most can be avoided by using proper Control procedures (e.g., using a double-blind design) and using proper control groups.
