Observation and Hypothesis Formation are examples of __________ reasoning.
Inductive
Prediction, experimentation and conclusion are examples of __________ reasoning.
Deductive
If you refine your hypothesis with new data, it is called __________.
Iterative
__________ lead to predictions.
Hypotheses
__________ is a possible explanation of observations and must be tested for validity.
Hypothesis
An experiment tests the __________.
Hypothesis
True or false: an experiment tests many variables.
False (one variable at a time).
In order to perform a valid experiment, there must be a test group and a __________ group.
Control
Hypotheses are (accepted/rejected) if experiments produce results inconsistent with the predictions.
Rejected
More experimentally supported predictions make a hypothesis (more/less) valid.
