Unit 1 List 2 Experimental Design Flashcards
claim
a generalization based on a reported statistically significant effect
constant
The factors that do not change during the experiment
Evidence
information collected via rigorous scientific methods that changes their belief in the truth of factual claims of the first to the fourth kind
Experimental bias
occurs when scientists’ hypotheses influence their results, even if involuntarily
Experimental control
something used as a standard for comparison to check the results of an experiment
Experimental procedure
Observation, Ask a Question, Form a Hypothesis, Design an Experiment, Make Predictions, Test the Hypothesis, and Form a Conclusion
Hypothesis
A statement about a specific research question, and it outlines the expected result of the experiment
Manipulated variable
independent variable or test variable
Qualitative data
data representing information and concepts that are not represented by numbers
Quantitative data
measures of values or counts and are expressed as numbers
Reason
the ability to recognize and understand the scientific method, concepts, processes, and applications used in the pursuit of knowledge
Responding variable
what the scientist measures as a result of the test variable
Scientific method
the scientific knowledge is the buildup of facts specialized in the science field.
Scientific model
a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes
Scientific question
a question that is written in a way that is helpful for completing scientific investigations
Scientific theory
a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment
Trends in data
its multidisciplinary and efficient usage
Valid experiment
how well you have controlled your experimental variables in order to maintain a fair test
