Welcome to my KZread Channel. This channel features three types of videos:
1: How To...
2: Problem-solving
3: Statistics
4: Programming in R
I hope you find these videos useful.

Thank you
Thank you sir
Alaaaasssss.....at last i found one good video on using ONE WAY ANOVA on SPSS. you really saved my time in recalling all my SPSS skills sir, i was searching for such a video for many days on INTERNET. HATS OFF TO YOU SIR🎩🎩🎩
very clear, thank you sir
Simple explanation using simple language. Kudos Eugene for the good work.
Just awesome sir... thumbs up for the good work.
thank you on what ground you chose 95% as your CI is there a rule or you just pick up what you want 95, 99...
Hi @3zJHN, 95% is an acceptable level of significance for many statistical tests. If you need a more accurate result, say if you are doing clinical trials or measuring effectiveness of medicines, 99% would be better. It is up to you what measure to take and report in your results. Dr E.
@@EugeneOLoughlin Thank you so much doctor for the clarification It is really helpful. Appreciate you reply 🙏🏻🙏🏻
This is the best tutorial i have found, i was able to get it, when u have some time please post one on Logistic Regression, Thank you
12 years later after you posted this, here I am learning something new. Thank you !
Thank you so much
Thanks very much, it's a helpful video
I truly appreciate your by Hand video series. It has been incredibly useful in my studies
you are amazing man ty for the information
how to display the equation on the chart if is greyed?
In the cost column, please advise if these are estimated or actual costs?
Hi Miriam, Costs can be either estimated or actual. Some components will be easy to determine cost. For example - in the mouse trap example above, the components can be accurately costed as they are individual items that must be purchased to build the mouse trap. So - the "Platform" component actual cost is 0.12 + 0.07 + 0.08 + 0.06 = 33 cent. For functions - apportioning cost is more difficult, but is a key part of Value Analysis. This is more likely to be an estimate and you may need to call on experts to help estimate costs. Hope this helps, Dr E.
@@EugeneOLoughlin Thank you
Pl
that graph is unreasonably ugly/ next video please…
Good Day, when I used your values in your example using the Excel spreadsheet, the T value obtained = 0.000455917. Can you say why this is or what is different between the formula you used vs the one in Excel?
Hi @Annaramjhingai, In my example I am using critical values from the t distribution tables to determine whether or not to accept/reject Null Hypothesis by comparing it to my t-stat. You can also use p values which tools like Excel and SPSS will calculate for you (it is very difficult to attempt by hand). As you have already seen, this is not the same as a t critical value. Your p value of 0.000455917 is very small. You compare this to your alpha value (0.025 in my example). As your p value is smaller than the alpha value, the decision is to reject Null Hypothesis. Finally, as your value of 0.000455917 is too awkward to report, you should report it as "p < 0.001". Hope this helps, Dr E.
How to do this when we have replicates for each? Eg. 3 measurements for August and 3 for November for all the rows. Should we take the means?
thanks a lot !
Thanks very much sir. You just save my day. I have an exam to write in an hour time. Thumbs up for this video👍
Sir, I greatly appreciate this with all of me. Bless you!
Mega vid, used it to create a voltage curve for the oil temp
where did you get alpha = 0.05 from? Is it because you are doing the test at a 5% significance level?
Hi Sara, The alpha value of 0.05 is based on 95% significance level (not 5%). Dr E.
This was very helpful 🎉
My friend showed me your channel. I was so affraid of R, forums seemed so complicated... I love how you explain everything step by step and the theory behind it. Thank you so, so much!!!
Great job!
You didn’t use the squared was that an oversight or it is not needed?
great video! just a question: is that footnote about the test being based on negative ranks useful for the interpretation? what does that tell us?
Thank you!
I am watching 1 hour before my exam 😂😂
So helpful! Thanks!😭
Very helpful love from 🇵🇰
This helped with my homework. Slowing down the video playback speed did the trick!
Thanku so much! Tomorrow is my exam and your video is so helpful ❤
Thank you, very useful for me. If you don't mind, may I know or recommend a book or journal about linear regression in your video?
So, how many of you are on the day of exam or a day from exam?
That's fking informative sir!!!
This is a good example of what the Internet was made for! Thank you.
Thank you. This was a great, simple explanation.
Thank you, your videos are excellent, it makes so much difference when you work by hand and explain why and how.
Hi sir, Thank you for your help🙏🏻. I have a quick question, when i sum up all of the (x-xbar) values i get 0 and then entire of the variance becomes zero what should i do?
I had no clue on how to calculate this but after watching this video I can confidently say I will never fail this.
this helped me with my gcse statistics which i did today, it came up too! thanks
.. but glad to say that .. I found that this learning is "so so very good and very useful" . Cheers Eugene .. God Bless You.
I'm sorry to say that I did not find this video "useful" ...
Thank you soooooo much for this video!!!! ❤🎉
big thanks from me sir
Thank you
A really helpful video, thank you!
