Scientific method helps researchers investigate psychological phenomena. Process consists of five main steps, sometimes breaking into six or seven. Researchers must observe, ask questions, test hypotheses, collect data
Scientific hypothesis is a testable explanation for natural phenomena. Hypothesis requires active observation and background research. Karl Popper advanced concept of falsifiability in mid-20th century
Hypothesis is an assumption proposed for testing purposes. Theory is a principle supported by evidence and data. Hypothesis is constructed before any applicable research. Theory has higher likelihood of being true than hypothesis
Hypothesis is an educated guess based on limited evidence. Theory is a well-substantiated explanation supported by strong evidence. Hypothesis serves as starting point for scientific investigation. Theory provides comprehensive explanation of natural phenomena
Research methods systematically observe, describe, predict and explain behavior. Hypotheses predict results and must be verified or disproved. Four types of hypotheses: null, alternative, one-tailed and two-tailed
Scientific method is a systematic way of learning about the world. Method involves making hypotheses and testing them through experiments. Anyone can use it by asking questions and finding answers
