Dr. Hadden wants to conduct a study that will allow him to make claims that apply to all college students. Which of the followin
g validities is he prioritizing? a. the statistical validity of the study b. the internal validity of the study c. the construct validity of the study d. the external validity of the study
The external validity is the type of study which basically depicts that the concept of the study result must be meaningful. The external validity mainly apply in the conclusion in the scientific concepts and study about the main context.
External validity is the type of validity in which we extent the result of the study across the different types of situations, times and people. In mathematics, the external validity concept is applicable for determining the statistical and the various computational methods.
Use elimination Multiply first equation by 4 12a - 8b = 56 12a + 9b = 39 Subtract both -17b = 17 b = -1 Plug in -1 for b 3a - 2(-1) = 14 3a = 12, a = 4 Final answer: a = 4, b = -1
