Answer:Validity
Explanation:
Validity is measure of how valid the research is which means it gives solid relevant result which were initially intended. It is a test of how valid both your design and method of the research is.
There are various factors that can affect validity of the research.
There are internal factors that can affect validity of the research those are the ones that occur within the study such as failure to monitor vital variables of the study or using the inaccurate instrument to gather the needed data.
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
- method use to collect data
- characteristics of the chosen population
- experiment effect
- interaction of subject selection
