• ### Statistics 101: Permutations vs. Combinations

Statistics 101: Permutations vs. Combinations.In this video we discuss the basic differences between permutations and combinations. Several examples are provided. This video is applicable to both statistics and finite mathematics. Enjoy! For my complete v

• ### Statistics 101: Combinations

Statistics 101: Combinations.In this video we discuss the basics of combinations as often learned in Finite Mathematics and Introductory Statistics. Several practical examples are provided along with how to calculate combinations by hand and using a TI-83

• ### Statistics 101: Permutations

Statistics 101: Permutations.In this video, we discuss the basics of permutations. Several examples are provided including calculations done by hand and using a TI-83+ calculator. Enjoy! For my complete video library organized by playlist, please go to my

• ### Statistics 101: Combinations - Losing Your Marbles

Statistics 101: Combinations - Losing Your Marbles.In this video we cover, step by step, one of the basic types of combination problems; selecting groups based on conditional criteria. If you are in an intro stats or finite math course you WILL see this t

• ### Statistics 101: Combinations - Playing with a Full Deck

In this video we cover, step by step, one of the basic types of combination problems; selecting groups based on conditional criteria using playing cards. If you are in an intro stats or finite math course you WILL see this type of problem. I walk you thro

• ### Statistics 101: Combinations - Dogs of the Dow

Statistics 101: Combinations - Dogs of the Dow.In this video we cover, step by step, one of the basic types of combination problems; selecting groups based on conditional criteria. In this example we choose stocks. If you are in an intro stats or finite m

• ### Statistics 101: Combinations - Under the Curve

Statistics 101: Combinations - Under the Curve.In this video we take a look "under the hood" of statistics and finite mathematics to understand how and why a "normal curve" is literally a lump of probabilities. We use simple combinations to build up to wh

• ### Statistics 101: Combinations - Nearly Normal

Statistics 101: Combinations - Nearly Normal.Where does the normal curve or "bell curve" actually come from? In this video we begin to answer that question using simple combination calculations. This video is more about what is going on "under the hood" w

• ### Statistics 101: Random Variable Basics

Statistics 101: Random Variable Basics.In this video we discuss the basics of random variables for statistics and finite mathematics. What is a random variable? How do we use simple random variables to model basic experiments and record observations about

• ### Statistics 101: Expected Value

Statistics 101: Expected Value.In this video we discuss the basics of expected value. If you have ever calculated a weighted average you can easily calculate expected value. Several practical and concrete examples are provided. Enjoy! For my complete vide

• ### Statistics 101: Discrete Random Variable Probabilities

Statistics 101: Discrete Random Variable Probabilities.In this video we discuss the basics of discrete random variable probabilities. When an experiment or process can only take on a finite number of outcomes (like a die roll) we can assign a probability

• ### Statistics 101: Discrete Random Variable Variance

Statistics 101: Discrete Random Variable Variance.In this video we continue our discuss about expected value. The expected value is simply the mean of a random variable. However that does not tel you how spread out or dispersed the probabilities are from

• ### Statistics 101: The Binomial Distribution

Statistics 101: The Binomial Distribution.In this video we learn the basics of the binomial distribution using the simple sales performance data of two salespersons. Given a fixed success rate and call volume, what is the probability of closing a certain

• ### Statistics 101: Binomial Mean and Standard Deviation

Statistics 101: Binomial Mean and Standard Deviation.In this video we learn how to calculate the mean and standard deviation for a binomial distribution. Two examples are provided and we tie the concept back into the previous video where we discussed cumu

• ### Statistics 101: Simple Binomial Sales Quota Analysis

Statistics 101: Simple Binomial Sales Quota Analysis.In this video we use the binomial distribution to assess the probability of two salespersons making the firm's daily sales quota. The relationship between success rate and sales call volume is explored.

• ### Statistics 101: Binomially Distributed Mac OS X User Rate

Statistics 101: Binomially Distributed Mac OS X User Rate.In this video we use real-world data to explore the binomial distribution. A certain percentage of Internet users do so on the Mac OS X operating system. If we select 25 random users, what is the p

• ### Statistics 101: Binomially Distributed Factory Accident Data

Statistics 101: Binomially Distributed Factory Accident Data.In this video we use the binomial distribution to answer a real-world question about the number of accidents occurring on a factory production floor. I do assume you have a basic understanding o

• ### Statistics 101: Joint and Marginal Probabilities

Statistics 101: Joint and Marginal ProbabilitiesIn this video we look at the individual and joint behavior of two stocks: General Electric (GE) and Apple (APPL). More specifically, we analyze the daily returns for the entire 2012 trading year for these tw

• ### Finite Math: Set Operations and Notation

Finite Math 101: Set Operations and NotationIn this video we discuss the basics of sets; elements, set notations, subsets, etc. I attempt to use real world examples to accompany the formal definition of set concepts. The ideas in the video are the foundat

• ### Finite Math: Venn Diagram Basics

Finite Math 101: Venn Diagram BasicsNot much mystery as to what this video is about; the basics of Venn diagrams. In this video we discuss intersections, unions, disjoint sets, and universal sets. I offer a (hopefully) useful way visualizing Venn diagrams

• ### Finite Math: Venn Diagram Region Method

Finite Math: Venn Diagram Region MethodIn this video we learn how to isolate certain regions of the Venn diagram using a simple method I teach the students I work with (I know it is taught elsewhere too). If we think of the Venn diagram as a "map" with di
