Answer: an explanation that organizes separate pieces of information in
a coherent way.
●● replicable
Answer: when others can repeat an experiment and get the same results.
●● hypothesis

explanation possible to any set of observations.
●● correlation
Answer: measurement of the strength of the relationship between two
variables
●● reliability
Answer: if a test produces the same result when researchers administer it
to the same group of people at different times, it has reliability.
●● Validity
Answer: A test is valid if it actually measures the quality it claims to
measure.
