CNSL 503 MODULE 1 PROBLEM SET
COMPREHENSIVE STUDY GUIDE 2026 FULL
QUESTIONS AND SOLUTIONS GRADED A+
◍ Ethical use of statistics.
Answer: 1) to communicate large amounts of information in a clear and
simplified manner 2) serve as a means of drawing inferences Ana's forming
conclusions about relationships between different variables. 3) provide
evidence to support claims or to frame an argument
◍ spreadsheet model.
Answer: computer model implemented via spreadsheet
◍ Nominal scale.
Answer: Variables that provide categorical info (blood type, college majors,
room numbers) (not greater than or less than)
◍ Statistics.
Answer: Encompasses the mathematical field that allows us to organize,
summarize, describe, and interpret different forms of information
◍ Control variable.
Answer: A variable that remains unchanged throughout the experiment
◍ Corner/Extreme Point.
Answer: -point in the feasible region where two or more of the boundary
lines of the constraints intersect
◍ sample.
Answer: Smaller subset of a group
◍ Importance of ethical handling of data.
Answer: Applies to data collection, analysis and interpretation.
, ◍ mathematical model.
Answer: uses mathematical relationships to describe or represent an object
or decision problem
◍ Inferential statistics.
Answer: Are performed for researchers to make inferences and
generalizations about populations based on data gathered from samples.
Calculations used for hypothesis testing (z-score, t-tests, ANOVA, and
correlation all analyses)
◍ mathematical programming (MP).
Answer: area in business analytics that finds the most efficient way of using
limited resources to achieve the objectives of an individual or a business
◍ optimization.
Answer: mathematical programming is often referred to as this
◍ Improper data collection can result in.
Answer: Biased and skewed results
◍ Redundant Constants.
Answer: -plays no role in determining the feasible region of the
problem-constraints and feasible region is revised
◍ What 2 things prevents you from solving the LP?.
Answer: 1. unbound solutions2. infeasibility
◍ Continuous variable.
Answer: Quantitative variable, can be broken down into infinitely smaller,
fractional components (Temp, time, length, speed)
◍ independent variable.
Answer: Variable that is manipulated in an experiment
◍ valid model.
Answer: accurately represents the relevant characteristics of the object or
decision problem being studied
