Math On Trial Vocabulary Flashcards
(25 cards)
Probability
Chance of an event happening compared to the number of outcomes
Non-independent Probabilities
When the probability of one event is dependent/influenced by the probability of another event
Inaccurate
When a calculation or estimation is nowhere close to being usable
Estimates
Approximation based on prior knowledge
Statistical Research
Numerical evidence or proof of a certain occurance
Erroneous
A very bad case of inaccuracy
Conclusion
What one draws from statistical research and probabilities
There doesn’t have to be one
Incontrovertible
Truth without the possibility of a doubt
Frequency
How often an event occurs during observation rather than a calculated probability
Arbitrary
Numerical value that has no application to the current situation
Fair
When an event happens without an outside influence
Generally close to calculated probability
Biased
When an event is influenced by an outside event
Normally not close to the actual probability
DNA Electropherogram
Picture of DNA used by forensic scientists
Threshold
Line dividing the likelihood of fair and biased events
Databases
Where statistical evidence is kept
Target Event
The result you want in a probability
Bayes’ Theorem
Used to calculate the probability of one event after a previous event occurred
Travesty
Obstruction or prevention
Simpson’s Paradox
When data seemingly contradicts itself because important information is withheld or missing
P-value
Probability that the same event occurs the same amount of times over several tests
Underestimating
Assuming small changes to large calculations cannot make a major difference in the final result
Exponential Growth
Rate of change than increases more rapidly as time passes
Sufficiently Mathematically Aware
Ability to understand math when presented in real life contexts
Model
Mathematical representation of a real life situation
