What is internal validity?
Internal validity refers to the extent to which a study can establish a cause-and-effect relationship between variables.
Why is internal validity important in research?
It's crucial because it ensures that the results of a study are due to the manipulation of the independent variable, not other factors.
Can you give an example of a study with high internal validity?
Sure! A randomized controlled trial where participants are randomly assigned to treatment or control groups typically has high internal validity.
What are some threats to internal validity?
Common threats include selection bias, confounding variables, and measurement errors.
