Below are the factors that has an impact on internal validity.
-size of the studied population
-instruments used
-history
-subject variability
-available time to gather data
- attrition
External validity are affected by the external factors such as the place where you conduct your research which may restrict the ability to obtain actual results . It can also be affected by the things like not being able to balance your subjects for example focusing on one gender and race eventhough your research is about all the types of people at large.
Crucial factors that affects external validity.
- The effect of time

<h3>Freedom of speech.</h3>
Explanation:
- Freedom of speech is a principal that advocates the freedom of a person to state his/her opinion freely and to impart information and ideas without any restrictions.
- However, in the case of Schenk v.

C. examining body camera footage to determine the extent of excessive use of force among police departments.
Explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
An unobtrusive data collection is a data collection technique used mainly in the social sciences to obtain or gather data without the researcher directly interfering or interfacing with the subject being studied. Thus, it doesn't influence the behavior, action or response of the subjects under study.
Hence, an example of unobtrusive data collection is examining body camera footage to determine the extent of excessive use of force among police departments.
