- Conditional Probability
This video discusses conditional probability, accuracy, and tree diagrams.
- Definitions
This video is used in the @RISK Lesson on Simulation Modeling. It discusses closed and open systems, complexity, internal and external numbers, impact causing change numbers (ICCNs), uncertainty, knowledge, and Kantian knowledge.
- Descriptive Statistics
More Videos and an Example Problem
This video discusses descriptive statistics, parameters, census, constants, statistic, sample, true average, sample average, random variable, true mean, data, standard deviation, inferential statistics, average deviation, and Chapter 4 from The Decision Making Book.
- Expected Value
This video discusses expected value, observed averages, reasoned out averages, opinion averages, true averages, random variables, random variables of interest, mean, probability distributions, and standard deviation.
- Graphing Revenue and Cost
This video is used in the @RISK Lesson on Simulation Modeling. It discusses graphing revenue and cost, fixed cost, y intercept, slope of a line, marginal cost, cost function, revenue function, break even, deterministic and probabilistic models, variables, random variables, constants, decision making, simulation, @RISK software, and uncertainty.
- Graphing with Straight Lines: Interpret Slope
and Y Intercept
- Probability Using Tree Diagrams
Video and Example Problem
This video discusses algorithms, tree diagrams (decision trees), probability, and decision making under risk. If you are working with a problem that involves stages or steps, think about using a tree diagram. For information on software that produces tree diagrams (decision trees), go to Using Decision Analysis Software.
- Probability Using Venn Diagrams
Video and Example Problem
This video discusses Venn diagrams, categorizing, conditional probability, and targeted marketing.
- Regression
This video discusses regression, Kant, knowledge, empiricists (experience), rationalists (reasoning), best fitting least squares line (BFLSL), patterns of the past and future, slope, y intercept, causation, predictions, and Chapter 5 from The Decision Making Book.
- S-Curves
- Simulation
This video is used in the @RISK Lesson on Simulation Modeling. It discusses graphing revenue and cost, fixed cost, y intercept, slope of a line, marginal cost, cost function, revenue function, break even, deterministic and probabilistic models, variables, random variables, constants, decision making, simulation, @RISK software, and uncertainty. You are not required to do the @RISK work; however, you may want to look at it to see what you will study in future courses.
- Simulation: @RISK Reports & Graphs
This video is used in the @RISK Lesson on Simulation Modeling. It discusses Kantian and virtual knowledge, empiricists and rationalists, random variables, uncertainty, complexity, descriptive statistics (mean and standard deviation), distributions, break even, @RISK reports and graphs (Input and Output Details, Output Graph). You are not required to do the @RISK work; however, you may want to look at it to see what you will study in future courses.
- Slope and Y Intercept
- Slope: Interpreting the Slope of a Line
- Slope: Linear Relationship for Price and Demand
