Extraneous variable a.k.a. Confounding vaiable is a variable that affects an independent variable n also afects a dependent variable at d same time confounding relatnship btn the independent and dependent variable. Mediating variable a.k.a. Intervening variable, it is a variable forming a link btn two variables that are causualy conected.
An experiment is when the researcher manipulates the independent variable and records its effect on the dependent variable whilst maintaining strict control over any extraneous variables. A correlation is a statistical relationship between two or more variables. The researcher makes a change in one of the variables to see what is affected.

The difference between internal and external validity is in their nature. Internal validity indicates if a study depicts relation between two variables. External validity on the other hand generalizes the study of the variables.
They are the same. These are names for the variables in an experiment that are controlled by the experimenter, as opposed to the output variables, the results you collect at the end of the experiment Hope this helped!
There is no such thing as "the usual sampling distribution". Different distributions of the original random variables will give different distributions for the difference between their means.There is no such thing as "the usual sampling distribution".

A moderating effect refers to a variable that influences the direction or strength of the relationship between two other variables. In other words, it impacts the relationship between the independent and dependent variables. Moderating effects help researchers understand under what conditions a relationship holds true.

The difference between continuous and discrete system lies in the variables. Whereas the continuous systems have dynamic variables, the discrete system have static variables.
Moderation occurs when the relationship between two variable depends on a third variable. The third variable is referred to as the moderate variable or simply the moderator
Moderating Effects - effect that large climate over nearby land areas. Winter temperatures are warmer and summer temperatures are warmer and summer temperatures are cooler than areas located away from large water bodies. The result is a small annual temperature range.
Literals are constants.

Field studies are conducted in real-world settings, while lab studies are conducted in controlled environments. Field studies tend to have more external validity as they reflect real-world conditions, whereas lab studies offer more control over variables. Field studies may be more challenging to control for extraneous factors compared to lab studies.
