Scientific Methodology: Observation Scientific methodology is a general style of investigation, not a rigid step-by-step process.

Scientific Methodology: Asking Questions Why do marsh grasses grow to different heights in different places?

Scientific Methodology: Hypothesis Inference: a logical interpretation based on what scientists already know Hypothesis: a tentative scientific explanation that can be tested further

Scientific Methodology: Experiment Testing hypotheses often involves designing experiments that measure factors that can change, or variables.

Scientific Methodology: Collecting Data Qualitative Quantitative data are numbers. data are descriptive.

Scientific Methodology: Analyzing Data analysis in science often relies on the use of statistics.

Scientific Methodology: Review
