BiologyChapter1: Data and the Scientific Method

- Qualitative (yes/no; recorded descriptions)- Quantitative (a number; quantity)

- draws conclusions through the logical process of induction- through induction, we derive generalizations from a larger number of specific observations- EX: "the sun always rises in the east"

- draws conclusions from the general to specific- used in math, computing- EX: if all organisms are made of cells (premise 1) and humans are organism (premise 2), then humans are composed of cells (deductive prediction about a specific case)

- observations lead to ask questions and propose explanations- leads to predictions that can be tested by observation or experimentation

- observation: your flashlight doesn't work- Question: why doesn't your flashlight work?- Hypothesis 1: - Hypothesis 2:- both these hypothesis are testable

- latin verb meaning "to know"- an approach to understanding the natural world- developed out of curiosity about ourselves, other life-forms, our planet, and the universe

-the heart of science- a search for information and explanation, often focusing on specific questions

- making observations- forming logical hypothesis- testing that is repetitive

Observations and analysis of data

The use of the senses to gather information, directly or indirectly, with the help of tools that extend out senses

-recorded observations- items of information in which scientific inquiry is based

- a tentative answer to a well-framed question; an explanation on trial based on available data and guided by inductive reasoning- a scientific hypothesis leads to predictions that can be tested by making additional observations or by performing experiments

If...then logic

1. hypothesis must be testable; check the validity2. must be falsifiable; there must be some observation/experiment that could reveal if such an idea is actually not true
