Document Summary
Week 11 field research and external validity. Confidence level of whether a study"s findings will reflect in the real world. High external validity is the goal when a researcher wants their results to be a representation of the real world. To increase external validity, randomization must be an integral part of an experiment employment. Researchers want to meet in the middle when it comes to internal and external validity. High internal validity can be balanced or changed by repetition; by constantly repeating the study in different environments or settings. External validity refers to how well data and theories from one setting apply to another. This question is usually asked about laboratory research: does it apply in the everyday. Experimental research designs that are conducted in a natural environment rather than in a laboratory. Applies the scientific method to examine an intervention in the real world.
