The document outlines the scientific method used in psychology. It discusses the 5 basic steps: 1) observe phenomena, 2) formulate a question/hypothesis, 3) test predictions through research, 4) draw conclusions, and 5) evaluate results and collaborate. It also describes different types of research (descriptive, correlational, experimental) and settings (laboratory, natural observation). Experimental research involves manipulating an independent variable to measure its effect on a dependent variable, while controlling for validity, experimenter bias, participant bias, and placebo effects. Data is analyzed using descriptive and inferential statistics to determine if results support hypotheses. Ethical standards require informed consent, debriefing, confidentiality, and humane treatment of research participants.
