You are the best teacher - Ever! I have just completed my MSc in Neuroscience and the first year terrified me as one could not pass the degree unless a pass mark was obtained for advance quantitative methods (stats). Before every lecture, I watched your tutorials, and they made perfect sense. I have recently started my PhD and STILL come back to your videos before I run any statistical tests on my data...just to refresh myself. Thank you so much, you will never realise what a service you are providing. I got an A* grade for Stats and frequently had to help other MSc students with their work. I just thought you ought to know how you have impacted my academic career.
Natasha, I appreciate the feedback. Good luck in your studies too. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
I've been instructed to report the standardised rather than the unstandardised coefficients and I found your video because don't understand why my supervisor has asked me to do this. Nor do I know how, when reporting the unstandardised seems to make so much more sense.
Hi, in this video in the table of coefficients it shows us two values of the standard error under the columns of unstandardised errors and these are certainly different from the standard error of the estimate we calculated . Why are there two values and how to interpret these values. they must be having some understanding points like how R squared has when it tends to zero and when it tends to one.
I agree. I would be curious why your supervisor wants you use standardized coefficients. Hopefully the video explained how to calculate the standardized coefficients in enough detail for you. Btw, what subject area are you studying?
Thanks for the tips! And I don't know if you know this or not, if you already have the info in excel you can literally just drag the file into your open spss and it will automatically load all the data into spss. < that is pretty much all I remember from my stats class ironically :P
Both standardized and unstandardized coefficients measure and mean the same thing. I think it really comes down to an a preference -- unstandardized coefficients are much much more common. Standardized coefficients remove the scale from the independent variable and it puts everything in standard deviation units. Honestly I think it can cause confusion, but since it is part of the SPSS output I did not want to skip it.
Thank you so much Mr. i have one clarification sir. In my study there are two variables with dimensions eg first variable 5 dimensions with its total and second one has the 10 dimensions with its total and my background variables are sex, locality, district, parent income, parent occupation. here, my doubt is how can i find out the variable like independent and dependent ? would you please give me the solution sir ?
I have a question about the significane of the correlation between the 2 variables. Is it represented as the significance in the ANOVA table or in the second table in your video?
Hm, maybe I should report both, to be thorough. I understand how to calculate them. I'm less confident about describing the values in words after the table. The unstandardised coefficients I see can be described using the formula, but not sure what to do with the standardised beta. I have investigated the distinct relationships between cortisol and fear, and cortisol and anxiety (arguing that it is insufficient to study "stress") in firefighters during fire suppression.
Dear statisticsfun I have data consisting of Two salts level containing quantitative treatments and want to apply regression on it. Should i apply linear or another one / Also suggest me the equation for it. Could it be Y= a + bx or Y= a+bx+cx2. I'll wait for ur reply. Please do response.
How I can deal with binary outcome variable (health status: good, poor) and in relation to a 5-likret scale (medication taking (always, usually, sometimes, never). I want to know the relationship between medication taking and health status. And how about the finding the relationship between two variables, independent and dependent both have a 5-likret scale answer???? Can you please help me with this.
Hi sir it is an urgent question I have a linear model in this form' y=b0+ b1 C+b2 P+ b3 CP I know who to create linear regression model for the above but my question about the addition of the fourth term can I consider this as an independent variable similar to C and P and then compute CP. Is that possible or not, please?
Hi sir I have independent variable comprised of 7 research items on three point likert scale which i have indexed into a single variable...Similarly I have a dependent variable loaded with 10 items on the similar scale. I got a very minimum R square value of 0.020. what I should do with this. However the tolarance is .767 and and VF is 1.304...with significance level of 0.000. I am quite worried about the model. Should I proceed with this or no...Please Help me.. Many thanks
Hello all, I am having 25 vegetation indices results of 10 healthy and 10 disease leaf of plant. For accuracy assessment regression will be calculated but having confusion of which indices I could consider for dependent and which for independent variables. Plz try to answer . thank you...........

the illustrations are very clear and helped me to understand the concept, thank you so much
Really.. this is the most effective video I have ever seen till now... Thanks... Keep up good lectures... Sherzad AM, PhD Student- Iraq
Great to hear! I was trying to decide whether to include that or not in the video, so I really appreciate the feedback.
Awesome. What's really useful to me is the elaboration on how to interpret the output tables. That's the way our course is tested.
Good to see some real input. I thought everyone was supposed to threaten each other on the youtube comments section.
Natasha, I appreciate the feedback. Good luck in your studies too.

Right! Good suggestion.

me during class: damn this is so easy I got this
me trying to do homework after class: Crap I forgot how to do it

You are probably right and should just report both. Interesting research study as well -- good luck. I would love to read it when you finish it.
You are simply Awesome..........Really Thanks a lotttttt
Thank You So much you taught me more than my teacher

Very nice, clear explained!!!!
Clear and Useful.
Thanks

sir Please make some video about hypothesis testing and statistical inference
Thanks for jumping in Cassandra
thank you! very easy to understand.
thanks man! Great video!
TeodoroYaki You are very welcome! Good Luck in your classes too.

Thank you for the lessons. Can you please make videos explaining linear mixed effects model?
Very useful. Thanks a lot!
Hello, how do I know if the line is actually a good predictor? Does it depend on the significance? Thank you!
thanks you.
I have a question about the significane of the correlation between the 2 variables.
Is it represented as the significance in the ANOVA table or in the second table in your video?
Under what circumstances would I report the standardaised coefficients? How do I report them?
How to interpret the std. error in the coefficients table?

Hi sir
it is an urgent question

can I consider this as an independent variable similar to C and P and then compute CP. Is that possible or not, please?

good video!!!!
Could you do nonlinear regression, for to calculate IC50?
Thank you!
Hello all,
I am having 25 vegetation indices results of 10 healthy and 10 disease leaf of plant. For accuracy assessment regression will be calculated but having confusion of which indices I could consider for dependent and which for independent variables. Plz try to answer .
thank you...........
what is parameters for my regression
Great Video, Thank you :-)
Great ! Thanks
thank you
thanks really
Tim Tam, I know I'm about 7 months late, but you would need to use logistic regression, not linear regression.
I did--share, like, subscribe; how about you?
