Explanation: 

Detailed explanation-1: -The internal validity of a study can be threatened by many factors, including errors in measurement or in the selection of participants in the study, and researchers should think about and avoid these errors.

Detailed explanation-2: -Internal validity examines the extent to which systematic error (bias) is present. Such systematic error can arise through selection bias, performance bias, detection bias, and attrition bias. [4] If internal validity is compromised, it can occasionally be improved, for example, by a modified plan of analysis.

Detailed explanation-3: -Bias can affect both the internal validity and the external validity of a study. The former is a much more serious issue. Internal validity refers to the inner workings of a study: Was the best design used?
