External validity is the extent that results from a study generalize to other people, places, and situations--how well the findings stand outside the study and the extent to which they can be replicated. The internal validity is that extent to which the study's design enables it to measure and study what it intends to study.

What is the difference between internal and external validity?
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.
What is the difference between intrinsic and extrinsic?
Extrinsic is external; intrinsic is internal.
What is the angle between two adjacent sides of a 12 sided regular polygon?
Any polygon has a total external angle of 360 degrees This is split between all the angles around the shape, n the case of a regular polygon they would also be equal, so the external angles would be 360 / 12, which is 30. However you need to know the internal angles As you know there are 180 degrees in a straight line, the external angle is 30 degrees as explained above, so the internal angle is 180 - 30, which is 150 degrees
What are the differences between validity and reliability?
validity is whether the results are valid so the data has no mistakes of as such in it whereas reliability is the dependability; when the results you have are accurate and are of enough quality.
Differentiate inferential statistic and descriptive statistic?
y=a+bx+e sample regression model differentiate between y bar and E(Y)?
