Question 4 The difference between internal and external validity is best described as: Internal validity tells us if the inferences drawn from the study population are true of the study population whereas external validity tells us if the inferences drawn from the study population are true of the target population. Internal validity tells us if the inferences drawn from the population being studied apply to other populations whereas external validity tells us if the inferences drawn from the population being...

One of the factors affecting a study's validity is the setting. For instance, a researcher would want to consider whether a laboratory setting is ideal for a study. There are numerous reasons why a laboratory can be ideal but also many reasons why a laboratory is not the best situation to run an experiment. As with most things we discuss, it really depends on the situation. For instance, some of the things to consider are accuracy, reliability, and consistency. These...
