In this video, I discuss some basic terms of probability. I start with the definition of a random experiment. I then show how the sample space is the set of all possible outcomes. I give an example of calculating the probability of a single event and discuss how the sample space grows with a compound event.
Further, I discuss the three types of probabilities. Empirical probabilities are based on past evidence, classical probabilities are known a priori, and subjective probabilities rely on our best judgement. #probability #math
This video shows a quick way to visualize data by creating a pie chart in Open Office Calc. I show how to create a basic pie chart, change it to a 3d pie chart, change the individual colors of the slices, add a transparency to the pie chart and add labels. #statistics #opensource
In this video, I discuss the importance of having a random sample. Random sampling helps to ensure that we can draw accurate conclusions from our analysis. (00:26) I discuss the difference between a random and non-random sample. (00:46) I discuss two main types of random samples: simple random samples and systematic samples. (02:40) I also discuss several types of non-random samples. Things such as focus groups, judgement samples, and convenience samples can still be useful.
This lesson discusses the basics of collecting data for statistic analysis. I explain the definition of a variable, and I discuss the difference between univariate, multivariate, and bivariate analysis.
I also discuss the difference between categorical data and quantitative data (02:57) as well as the difference between continuous and discrete measurement. #statistics #datascience #analytics
This video discusses some common mistakes people make when conducting statistics and data analysis.
At (00:37) I discuss why drawing conclusions from small samples, making conclusions from non-random samples, drawing inferences from random events, and the hazards of poor survey methods can give misleading results.
At (02:49) I argue that correlation does not imply causation, we can not generalize statistical findings to individuals, we must be aware of unconscious bias, and difference between significance and importance.
This video begins a new series discussing the ways that businesses can use statistics to improve efficiency and effectiveness. At (00:50) I discuss the definition of statistics and data science. I also discuss the difference between descriptive and inferential statistics (01:42). #math #statistics #business
The Green to Gold program allows you to earn either a Bachelors or Masters degree while simultaneously earning a commission as a 2nd Lieutenant in the US Army. If you are considering joining the Army, this is a great option. The Army will pay for your school, and you will enter service as an officer instead of an enlisted service member. This program allows you to become an officer in the Army and earn your degree. #education #army #freemoney #payforcollege
Joining the Army can be a big decision. The good news is that the Army will provide housing and food for all of its soldiers. Depending on your rank and marital status, you could live in the barracks, or the Army could give you money, called BAS, to pay for an off post apartment. If you live in the barracks, you also get to eat for free in the Chow Halls (also called Dining Facilities DFAC).
I hope this video helps you in making your decision to join the military. #bas #bah #army
Stefan Molyneux's book: Universally Preferable Behaviour argues that universal morality can be developed based on the Scientific Method. This book discusses the requirements for virtue and some of the preconditions for morality. I like how the book approaches morality and ethics from a secular perspective. In an increasingly interconnected world, we need valid guidelines for ethical behavior that can be independent of different religious beliefs and cultural norms. I think this book makes a good attempt at solving this problem. #ethics #morals #stefanmolyneux #upb
Aaron Clarey's book : Bachelor Pad Economics offers a common sense philosophy of living: we should live for ourselves and make ourselves happy.
While this seems simple, we also have to reconsider a lot of preconceived notions. Should we attend college? Do you really need to save for retirement? Will social security be there for us? What are the values of living a minimalist lifestyle?
I discuss some of the more relevant concepts from the book. This book discusses everything a man needs to know about cars, housing, investing, retirement, girls, dating, and much more. #personalfinance #investing #money #women #success #life #mgtow #bookreview
David McKnight's book: The Power of Zero is a must read for anyone who wants to invest, retire, and learn how to manage their money. Learn how to plan your investments for a tax free retirement.
The book talks about the advantages of a Roth IRA over a traditional IRA. Other topics dissected are the impact of provisional income on social security benefits, life insurance retirement plans, and estate planning.
I am not a financial advisor in any way. This is not financial advice; it is merely a summary of concepts found in the book.

This is a book review of J.L. Collin's book: The Simple Path to Wealth. I discuss what I consider the two central tenets of the book: Saving 50% of your income in a total stock market index fund, and how to determine when you are officially "financial independent."
I recommend this book for anyone that wants to understand how they can retire and invest without the chaos of stock picking, commissions, market timing, and dealing with overzealous brokers. #wealth #money #bookreview #financialsecurity
"The Richest Man in Babylon" shows how to manage money intelligently. The author gives sound investment advice in the form of a parable. I discuss the six laws of wealth that can help you save money, invest smarter, and achieve financial security. #money #investing #finance #wealth
This video shows how to change the bearings on your inline skates. Changing the bearings on your rollerblades allows you to save money by purchasing wheels without bearings pre-installed. Removing roller blade bearings also allows you to clean your bearings and extend their useful life. #skating #rollerblades #inlineskates
