AP students in psychology should be able to do the following:
 * Differentiate types of research (e.g., experiments, correlational studies, survey research, naturalistic observations, and case studies) with regard to purpose, strengths, and weaknesses.
 * Describe how research design drives the reasonable conclusions that can be drawn (e.g., experiments are useful for determining cause and effect; the use of experimental controls reduces alternative explanations).
 * Identify independent, dependent, confounding, and control variables in experimental designs.
 * Distinguish between random assignment of participants to conditions in experiments and random selection of participants, primarily in correlational studies and surveys.
 * Predict the validity of behavioral explanations based on the quality of research design (e.g., confounding variables limit confidence in research conclusions).
 * Distinguish the purposes of descriptive statistics and inferential statistics.
 * Apply basic descriptive statistical concepts, including interpreting and constructing graphs and calculating simple descriptive statistics (e.g., measures of central tendency, standard deviation).
 * Discuss the value of reliance on operational definitions and measurement in behavioral research.
 * Identify how ethical issues inform and constrain research practices.
 * Describe how ethical and legal guidelines (e.g., those provided by the American Psychological Association, federal regulations, local institutional review boards) protect research participants and promote sound ethical practice.
