Stat 305 Exam Study Guide Solutions
Chaotic System - ANSWER✔✔-a system which minuscule differences can causes entirely different
results.
Quantitative Theory - ANSWER✔✔-Number theory
data - ANSWER✔✔-information we can record
Engineering Statistics 3 parts are... - ANSWER✔✔-Collect data
summarize data
draw formal inferences and conclusions off data
Observational Study - ANSWER✔✔-you don't effect the study, just happens naturally
Experimental Study - ANSWER✔✔-You effect the study by manipulating variables to regulate the study
Enumerative Study - ANSWER✔✔-A study on a certain group of things or people and only focus on those
things
Population - ANSWER✔✔-the entire group that is being represented through a sample during a study
Sample - ANSWER✔✔-group that is actually tested and data collected during a study, represents
