approximation - ✔️✔️you can say "this is the real thing, and this is what were replacing
it with
refinement - ✔️✔️making project more precise
altitude - ✔️✔️how much specificity
heuristic - ✔️✔️often useful but not guaranteed to solve a problem
discrete sample space - ✔️✔️consists of a finite set of outcomes
continuous sample space - ✔️✔️contains an interval (either finite or infinite) of real
numbers
event - ✔️✔️a subset of a sample space of a random experiment
venn diagrams - ✔️✔️represent a sample space and its events
mutually exclusive - ✔️✔️when two events share no common elements they are
____________
permutation - ✔️✔️an ordered sequence of the elements
number of permutations of n elements - ✔️✔️n!
combinations - ✔️✔️number of subsets of r elements that can be selected from a set of
n elements
assumption - ✔️✔️a statement that you ACT as if it were true when you don't really
know if it is true
mechanistic model - ✔️✔️built from our underlying knowledge of the basic physical
mechanism that relates variables
empirical model - ✔️✔️uses our engineering and scientific knowledge of the
phenomenon, but it is not directly developed from our theoretical or first principles
understanding of the underlying mechanism
least squares - ✔️✔️a method for estimating the parameters in regression models
