(module 3) hypothesis
a testable conjecture about how something works
(module 3) null hypothesis
a prediction that there is no difference between groups or conditions, or a statement or an idea that can falsified, or proved wrong
(module 3) replication
the data collection procedure of taking repeated measurements
(module 3) sample size (n)

(module 3) accuracy
how close a measured value is to the actual or true value
(module 3) precision
how close the repeated measurements or a sample are to one another
(module 3) uncertainty
an estimate of how much a measured or calculated value differs from a true value
(module 3) theory
a hypothesis that has been repeatedly tested and confirmed by multiple groups of researchers and has reached wide acceptance
(module 3) control group
in a scientific investigation, a group that experiences exactly the same conditions as the experimental group, except for the single variable under study
(module 3) natural experiment
a natural event that acts as an experimental treatment in an ecosystem
