Normal retirement age is 65. Refers to the extent to which the results of a research design can be generalized beyond the specific way the original experiment was conducted. Ecological validity examines, specifically, whether the study findings can be generalized to real-life settings; thus ecological validity is a subtype of external validity. External validity, on the other hand, forms a great experiment design's cornerstone and is a bit complex to achieve. Validity refers to the degree to which an instrument accurately measures what it intends to measure.
