A
When analyzing data, scientists must:
Organize it in a logical manner
The dependent variable
Changes in response to the independent variable
What is peer review
An evaluation by scientists in the same field
A hypothesis is best defined as
A possible answer based on observations
A blind experiment is conducted to
Prevent researchers from knowing group assignments
The scientific method is best described as:
A pattern of investigation procedures
Scientific inferences are
Based on observations using scientific methods
When recording observations, scientists should
Record all results, even unexpected ones
During the research phase of the scientific method, scientists should
Examine reliable sources and existing knowledge
Bias in scientific research can be reduced by
Running multiple trials and keeping accurate notes
Constants in an experiment are
Factors that remain the same
For a hypothesis to be considered valid, it must:
Produce the same results when repeated
What is the purpose of a control in an experiment
To provide a standard for comparison
What is the primary purpose of stating a problem in the scientific method?
To identify what will be investigated
The independent variable is
The factor that is changed to see its effect
The responsibility of scientists includes
Minimizing bias in investigations
A valid scientific experiment must be
Measurable and repeatable
If an experiment doesn't support the hypothesis
The hypothesis or procedure should be revised
When sharing scientific data, researchers should
Share through reports and conferences
What is the 4 variables in a scientific experiment
independent variable
dependent variable
