Science: experiments Flashcards
In an experiment, what is:
Comparing a control group and an experimental group - these groups are separated by one variable
Experimentation
In an experiment, what is:
• Observation • Measurement • Samples • Involves organization of the data
Data Collection
In an experiment, what is:
- Is the data reliable?
- Does the data support the hypothesis?
•Analysis
In an experiment, what should you always look for?
The purpose.
Type of reasoning?
- Starts with general known facts and comes to a specific conclusion
- ex) All wasps have stingers. That is a wasp; therefore, it has a stinger.
Deductive Reasoning
Type of reasoning?
- Creates broad generalizations from specific observations
- ex) That wasp has a stinger. Therefore, all wasps must have stingers.
Inductive Reasoning
•A valid SCIENTIFIC EXPERIMENT comes from?
- Logical procedure that leads to
- Reasonable explanations from
- Gathering sufficient evidence!
- The variable being changed by the scientist (input).
- Affects the Dependent Variable
- What is happening/changing
Independent Variable
- The variable being tested in a scientific experiment
* What is observed or measured (output)
•Dependent Variable
Type of correlation?
as one variable increases, the other variable decreases
Indirect/Negative Correlation
Type of correlation?
as one variable increases, the other variable increases
Direct/Positive Correlation
Type of evaluation?
- Record Keeping
- Data Management
- Graphing Data
Quantitative Evaluation
Type of evaluation?
- Interviewing
- Case Studies
Qualitative Evaluation
Type of results:
the degree to which several measurements provide answers very close to each other. (reliable data)
Precision
Type of results:
• describes the nearness of a measurement to the standard or true value. (valid data)
Accuracy
