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.

Really.. this is the most effective video I have ever seen till now... Thanks... Keep up good lectures... Sherzad AM, PhD Student- Iraq

the illustrations are very clear and helped me to understand the concept, thank you so much

[statisticsfun]

Great to hear! I was trying to decide whether to include that or not in the video, so I really appreciate the feedback.

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.

[Trazynn]

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.

[packzutrus]

Good to see some real input. I thought everyone was supposed to threaten each other on the youtube comments section.

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.

[yotamdalal]

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?

[statisticsfun]

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?

[mudharalaubedy]

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?

[deearosalky]

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 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

[sophiediestolpertnie]

Hello, how do I know if the line is actually a good predictor? Does it depend on the significance? Thank you!

[VengoRegis]

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 ?

[statisticsfun]

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.

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

[rupalisurase]

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

[htoomyataung]

sir Please make some video about hypothesis testing and statistical inference

[yasinmohamed]

Thank You So much you taught me more than my teacher
