My name is Dane McGuckian. This channel contains videos designed to introduce the public to my Statistics instruction site: www.statsprofessor.com/
The site was created to help students, help themselves, learn statistics. The site has over 700 short videos of me solving Statistics problems traditionally found in introductory Statistics courses.

A useful way to think about money and government debt (for a country that controls its currency).
This is a long (possibly boring) video that may provide you with a new way to view government spending and government debt in a country like the USA. A student asked me to create this after I discussed a metaphor for government spending in class. The metaphor came to me after I realized that I had given a class too many extra credit points on an exam. I hope the video will provide you with a different way to think about government spending and which spending is worthwhile.

A Repeatable Path To Wealth-a post for my students
Просмотров 995 месяцев назад
A lot of my students at the university have complained over the years that they are not taught practical lessons that could serve them in their everyday lives. There is a good reason for this actually, but putting those reasons aside, I thought I would try to pass on some useful information to my young students. I wish I had this sort of lesson when I was an undergraduate. The original post can...
Using the complement of "at least one" to solve an otherwise challenging probability problem

In this video, I demonstrate how to use a useful complement to solve a probability problem. This approach turns a very difficult problem into something that is very manageable. This is a homework problem from my website: STATSprofessor.com.

Probability Of a Type I Error: Three Cases
Просмотров 1,1 тыс.Год назад
In this video, I explain cover the probability of a type I error when testing a hypothesis. Before watching this video, you should be familiar with the basics of hypothesis testing, and you should know how to define a type I error. An introduction to hypothesis testing can be found in my playlists for 8.1, 8.2, and 8.3.
Testing for an Interaction in Two-Way ANOVA
Просмотров 1,2 тыс.Год назад
This short video is for students learning to interpret Two-Way ANOVA tables. This should not be the first video you watch on the topic, but it will be helpful for those that have had at least an introduction to Two-Way ANOVA. The first step is to test for an interaction effect. If one exists, you should not test for main effects. If the p-value for the interaction effect is small, we conclude t...

Another example: factorial counting resulting from applying the fundamental counting rule
Просмотров 8514 года назад
In this video, we solve a counting problem using the fundamental counting principle, and the result is a factorial. There is a rule of counting sometimes called the factorial counting rule. It is really an application of the fundamental counting principle. This video is part of the content available for free at www.statsprofessor.com
The Monty Hall Probability Problem from Let's Make a Deal
Просмотров 6 тыс.4 года назад
The Monty Hall Problem is a famous probability problem. It was featured in the 2008 film "21." In the 70s, the game show Let's Make a Deal was hosted by Monty Hall, and sometimes contestants would guess which door among three hid a large prize. After making their guess, Monty Hall would show the contestant one of the doors that did not contain the prize and offer the contestant a chance to chan...
The basics of basic probability

Finding the z score associated with the top 5th percentile of the standard normal distribution
Просмотров 15 тыс.4 года назад
In this video, we show how to find a measurement corresponding to the 95th percentile of the normal curve using a typical z table. The reason we are covering this example is that the percentile places you exactly in the middle between two z scores, so we discuss the best way to handle those situations when they occur.

Currently studying for my statistics final. Your explanations are very clear it helps so much. Thank you for the problem solving videos.
Why when you get difference, you dont subtract 2nd-1st??
nice god bless you 🥰
This is a right side tho not equal
Thanks Prof.🙏 lots of love from India ❤❤
Thank you very simple and clear
Impressive !!! So smart delivery to a complicated concept !!
It is very useful🎉
why is it at most for one tailed test and exactly α for two tailed tests?
Can you please share the table picture. I'm unable to find it anywhere. Or you just tell me how I search for this table.. kindly response it .
What's the point of finding the z score exactly?
The z score enables us to look up the probability using a z table (or Calculus or an app that calculates the area under the normal curve). Without the z value, we would have to use the binomial distribution which is computationally difficult even for powerful computers. It’s less of an issue with today’s computers but it used to be near impossible to do the calculations by hand for problems with large n values. Even fairly powerful computers struggle to do the work quickly, so programmers might still opt to use approximations like this in their code when speed is more important than precision.
I wanna be this guys friend. Saving my stats grade on video at a time lets go!
Thanks It's clear
Fans from Sri Lanka 😊
😊
Your hands are so beautiful
Thank you :)
very helpful and precise
Thanks 👍

hi, i did math stats, anova and regression end of last year, this year i did stochastic and im currently doing time series. I want to deepen my statistics knowlege any sugestions on which courses i should do next?
Which book is reminded for table of z test
Best teacher❤🎉
how to compute manually for Predicted Residual SS (PRESS) that SAS output in that table below (the one table with: Sum of Residuals Sum of Squared Residuals Predicted Residual SS (PRESS))
Thanks
I genuinely, from the bottom of my heart, appreciate your existence. You’ve lifted the heavy burden of not understanding this rule off of my shoulders. You literally explained this in such a simple manner. THANK YOU 😭🙏
you are awesome and very helpful, thank you!!
Thanks bro 🙏❤️
What's the value of x
excellent explaination. Thanks
What's tha difficult part in using online resources for studying? There are too many but only one will fit your style of learning... And for me this ONE is the only video that has lead me to understand what I am seeking for after so many videos this is the only one that fit my logical understanding😂
Absolutely brilliant explanation, thank you!
very nicely explained
Thanks den
Thank you from Pakistan.
You should subtract the numbers instead of adding them
You laterally safe my life ❤thanks
Easiest way to explain it in my opinion is the contestant should NOT want to guess correctly at the start and because 2 of the 3 doors are empty that means the contestant has a 67% chance of ending up with an empty door which is good. If you guessed an empty door correctly, the only door left after the next step is the door with the prize.
THIS IS HELPFUL, IF I MAY ASK SIR WHY IS IT ONE TAIL?
Thank you very much i now know how to use the z table and how to find critical region iam beginner student also help in financial maths your explanation is so clear Prisca from Zimbabwe
1.33 its z score bring .1292 a probability
No one could teach me. Nooo one
what you can do when the rate is not given?
Thank you for such an easy yet complete explanation.
Thank you!
Man you are a real lifesaver. 🙌
thank you so much, this was very helpful
The equation changes as soon as you offer the option of switching, the option is either blue box or yellow box in reality, which is a 50/50 chance of being both right and wrong. very simple.
No. 1/3 of the time you pick the correct one the first round. The only way to win when staying is if you were correct in the first round. That means you only win 1/3 of the time when staying. You pick the wrong one 2/3 of the time in the first round. You always win if you switch when your original pick was wrong. Which means you win 2/3 of the times when switching. You could think of it as choosing between the door you picked or both of the other doors. He just opens one of them before you've answered.
A dash of communism with my biostat
but where do you put the 63.95 in the first class or the second one?
Thank you sir especially for the part b) explanation..i was so confused when trying to locate the Z value on the Z table! Now after seven hours i can confidently feel in my assignment answer 🎉😅
Thanks . Very well explained video. Straight to the point !!!
