In this video I tell the story of Joy Milne and her ability to smell Parkinson's disease and use part of that story as an intro to learning the characteristics of the binomial probability distribtion. We learn how to create binomial probability distributions using excel and the binomial formula..
1 hr 2 min Video
Big review of basic laws of probability and counting principles . This is a recording in front of a live classroom.
17 min Video
In this video we practice using various counting principles in sample problems.

17 min Video
In this video we practice using various counting principles in sample problems.
21 min Video
Here I present some of the basic rules for counting techniques needed in an intro to probability course.
3 min Video
We explore the birthday problem: What is the probability that at least 2 people share the same birthday in a classroom of 25 people?
23 min Video
This is part of 4 of 4 on the basic laws of probability. This podcast focuses on conditional probability and the test for independent events.
13 min Video
This is part 2 of a 4 part notes on the basic laws of probability.
20 min Video
These notes on probability will be broken into a 4 part video.This is part one of the guidedd notes on probability
22 min Video
In this video I begin to introduce the laws of probability very simply through looking at cards, dice, and coin problems..
8 min Video
In this video I show how easy it is is to compute residuals and make a residual plot in excel.
17 min Video
In this video I show a fast and easy way to retrieve the scatterplot and correlation coefficient and examine the strength and direction of the association of a scatter-plot using excel.
14 min Video
In this video I pick a problem from the textbook to work through with you and we calculate residuals and make a residual plot. We then use the residual plot to decide if the linear model is appropriate for the data.You may want to pause the video and enter the data and practice computing residuals along with me.
15 min Video
This a live clip from an actual classroom where we learn how to compute residuals using a TI-83 and learn the definition of a residual.I also show how to compute the sum of the squared residuals.
17 min Video
In this lesson we explore the association between two variable via looking at scatter-plots and computing the correlation coefficient. This is shown using a TI-83.Lesson6 guided notes.
11 min Video
This is a clip from a live classroom where we do a warm up problem together and review how to numerically and graphichally summarize a data set via making a boxplot and histogram on TI-83 and we use the TI-83 to gather numerical descriptors.
9 min Video
This is a clip form a live classroom where I work through some problems in the textbook involving z scores and boxplots.We review how to find outliers as well.
15 min Video
In this video I pull a couple of examples out of our textbook to work through (for extra practice)involving z scores and boxplots.
5 min Video
This is a clip from a live classrooom where we work through a homework problem together involving Chebyshev's theorem.
9 min Video
This is a clip fom a live classroom where we work on some problems together out of the textbook and practice using Empirical rule and Chebyshev's inequaltiy.
20 min Video
In this video I explain the difference between Chebyshev's inequality and the Empirical rule for bell shaped data.
23 min Video
In this lesson we will explore the definiton of a z score and how that relates to percentile rank. We will also explore a data set to see if there are any outliers in the data. To determine if there are outliers we will create a modified boxplot on a TI-83 but we will also use the fence criterion. (lesson5 guided notes)
24 min Video
In this video, which is a clip from a LIVE classroom, I review how to find variance and standard deviation by hand and also go over the mathematical notation for measures of central tendency and dispersion.
2 min Video
In this video I show how to retrieve mean, median, mode and standard deviation at the touch of a button using excel(with megastat add in). We take a data set (people's test scores) and practice making stem and leaf and boxplots in excel. We discuss mean, median, and mode and the relationship to skewed distributions as well..
19 min Video
In this video we discuss the meaning of various numerical summaries such as mean, median , mode, standard deviation, and variance. I also demonstrate how to obtain those descriptive statistics by formula and using technology.(Lesson3 guided notes)
3 min Video
In this video I make a line chart, bar chart , and pie chart using excel.
17 min Video
This is a clip from a live classroom so you will hear me interacting with students as I guide them through some of the statistical jargon that is being used and I also review how to make data displays such as pie charts and histograms using both excel and TI83.
15 min Video
You can make boxplots, stem and leaf plots, dot plots , boxplots, and histograms at the touch of a button in excel and I will show you how in this video.
12 min Video
I demonstrate how to use a TI-83 and excel(with megastat)l to report numerical summaries such as mean and median and standard deviation of a data set quickly and easily.
8 min Video
In this podcast we take a data set and create a histogram on the TI-83 to display the income distribution and discuss the shape of the distribution. Sometimes you can tell whether a distribution is skewed right , skewed left, or fairly symmetric just by looking at a histogram but sometimes it's not that obvious.
26 min Video
Why do we need to learn and study statistics? In this podcast I begin to answer that question and I introduce some statistical jargon and terminolgy and provide an intro to ways of displaying data. Lesson 1; guided notes
