What type of reasoning, inductive or deductive, was used to form our hypothesis?
Inductive reasoning is used to form hypotheses.
What type of reasoning, inductive or deductive, was used to make our prediction
and perform our test?
Deductive reasoning is used to make predictions and perform tests
A scientific hypothesis is able to be proven true?
False. We don't prove hypotheses!
Which requirements scientists adhere when formulating hypotheses?
Hypotheses must be testable and falsifiable, cannot rely on faith, and cannot be
based on metaphysical or supernatural factors or forces.
Did we support or reject our hypothesis?
We supported our hypothesis.
Did we "prove" our hypothesis?
No! We never use the word "prove" to describe our hypotheses.
Can we consider our hypothesis "true," "fact," or "correct?"
No! We do not use any of those words to describe our hypotheses. We can only
find support for our hypotheses.
, control subject
A control subject is treated as closely as possible to an experimental subject
except that he or she does not get the experimental treatment.
What are the advantages of using a double blind experiment?
Given that both the researcher and test subjects do not know who is receiving
the treatment, it minimizes the effects of human bias on the results.
Sampling error can be best reduced by
increasing the sample size. Sampling error refers to the differences between a
group of experimental subjects and the population as a whole. The researcher
needs to make sure that the test subjects adequately reflect the general
population, and the only way to do this is to have an adequately large sample
size in the experiment.
What is wrong with the following statement: "Basic science has no real practical
use, and therefore should not be funded with public money" (e.g. government
grants)?
Without basic science, it is unlikely that applied science would exist. Scientific
discoveries in basic, or "pure," science usually precede their applications. A lot
of very important scientific discoveries would not have been made if we were
only focused on solving problems or creating new things for profit.
What term is used to describe an individual's personal experience or
endorsement?
anecdotal.
Peer-reviewed scientific information is published in a?
primary source
