Relatjve Frequancy And Risk Flashcards
What is relative frequency
The frequency relative to the total number of trials
Relative frequency equation
Probability of something happening = number of times it happened / number of trails
What makes the probability more accurate
The more trials the more accurate the probability will be
How can relative frequency help spot bias
Can you find out if a coin spinner or dice is fair
Estimated probability of a risk equation
Estimate the probability of risk = Risk of it happening / the number of things 
What is absolute risk
How likely an event is to happen
What is relative risk
How much more likely an event is happening to one group compared to another
Relative risk equation
Risk for group A / risk for group B
