Graph the function f by starting with the graph of y = x2 and using transformations (shifting, compressing, stretching,
and/or reflection) .
-f(x) =6x2-12x+5
External Validity
The extent to which the results of a study can be generalized to other situations and to other people outside of the experimental setting.
Internal Validity
The extent to which a study can demonstrate that a causal relationship exists between two variables, free from the influence of extraneous variables.
Single-Case Experimental Designs
Research methods that focus on obtaining detailed information from individual participants to assess the impacts of interventions.
Interventions
Actions or processes of intervening, designed to improve health or alter the course of a disease, typically referring to treatments, therapies, or programs.
