Thank you very much from Agadir town
My pleasure!
Clearest educational video I have ever watched. Thank you!
Great video thank you!
My pleasure - glad it helped!
Very helpful!
This is very helpful. Thank you so much. Is there any specific marker to check the distribution? Or is it just the histogram? How do we write that in the paper? Is it just by looking at the histogram?
Great video! The explanation is excellent!
Thanks for the feedback. Glad it helped!
Very informative video! I got a data (sample size more than 100) where the z value of skewness and kurtosis fits into the range of +3 and -3, which suggest the data is normal. But the kolmogorov smirnov test suggests the test is non normal. What inference or conclusion can be drawn from this? is the data normal or non normal?
How can I do a correlation with only data? I do not have any surveys
?
Hi Ronin, why did you have a bandaid on your arm?
This is good but how do I know what data to enter. Do you know a statistician who could help me?
I had to use spss previously, didn't like it. have to use it again... still don't like. no choice in the matter though. i have a Q regarding it as we will use qualtics to do a study, and spss for the data. which do you build the 'questions' for the qualtric questionnaire in? you listed the colors, can those colors in name under variable view be individual questions?
SPSS is the fucked
Thanks so much for leaving this information up-- you have a very nice presentation style. It was very helpful!
My pleasure. Thanks for your kind words.
Thank you very much ❤
I am returning to SPSS after not having used it for years. This was so helpful to remind me how to use SPSS. Thank you!
Glad it was helpful!
can u please share a link of data set you used in this video for practice? Thanks
Sorry for the late reply and the need to say no. The dataset I use here is just for my class.
what should i do if all my dots are clustered near the bottom? there's a lot of them so it just looks like a rectangle
Thank you so much for this video! I have a quick question: is it possible to do a spearman's rank correlation test with an ordinal variable (1-7 scale) and a nominal variable, for example age that have been sectioned into groups? If not, is there a way to see if there are any correlations between these two variables? Thanks again!
Hi! My pleasure. Nominal variables should not be used with Spearman. If age has been chunked into 3 or more groups, it would be an ordinal variable as well and Spearman could be used. If age is just two groups, you would want an independent samples t-test or a point-biserial correlation.
This was extremely helpful, thank you! I'm a bit more optimistic about using SPSS now :)
My pleasure! Best wishes to you!
Thank you so much for the informative video!!! Truly appreciated it 😍😍
My pleasure - glad it helped!
i have a test tomorrow and i came across your channel an hour ago and this is the best and simplest content explaining SPSS !!! your channel is really underrate thank you so much for this educational content keep going
Very cool! Glad I could help - hope your test went well!
Thank you so much. I was having trouble deciding wether Pearson or Spearman were appropiate. I now know its Spearman.
Hooray!
Thank you. Lucky students.
My pleasure! That is very kind of you to say.
Thank you! very helpful
My pleasure!
thank you SOOOOOOOOOOOOOOOOOOOOO much
My pleasure!
This was extremely helpful, thank you so much!!!!
My pleasure. Glad you found it helpful.
if there are a lot of cases clumped together, what kind of graph can we use to show correlation? I have a statistically significant correlation between household income and credit debt, however the scatter plot looks clumped together...?
Spearman would be more flexible and appropriate in this case - it can handle lumpy data better than Pearson
WHY SHE TALKING MORE JUST SHOW AIM OF THE VIDEO AND OVER, FUK
Tough subjects are great when you have a good teacher. I wish you were my bus. analytics professor. I hate that mf so much.
So what about ordinal data? Scale responses, agree-disagree? How do I make an "appropriate" graph for those? Do I just mark those as scale-type data? You confused me xD
From my understanding, statisticians disagree here. Some say it is OK to use a histogram for ordinal data (see, for example, sphweb.bumc.bu.edu/otlt/mph-modules/bs/bs704_summarizingdata/bs704_summarizingdata4.html#:~:text=When%20one%20is%20dealing%20with,categories%20have%20an%20inherent%20order). Others say you should not use a histogram for ordinal data and should use a bar chart or box-and-whisker plot instead (www.uni-bamberg.de/fileadmin/eng-ling/fs/Chapter_19/411Frequencydata.html).
@@virginiawickline2609 You rock! Thanks a lot. Appreciate the sources too :)
Thanks a lot, Madam, for your lovely explanation. My question related to the normality: Can we run a normality test (Shapiro or k-s test) to make a decision rather than usage figures, because for beginners like me, I can not judge on the normality from figure or you must decided on figures. Thanks in advance
My pleasure! Absolutely a normality test is appropriate. I run out of time to also teach this during my class (which is the primary audience for this video), but if I were doing it myself for research, I would rely on a K-S (Komolgorov-Smirnov) test myself.
@Virginia Wickline So, if the normality is violated, then the spearmen coefficient is a suitable alternative for pearson to make the correlation or not mandatory
@@fadhilfp6 If normality is violated, Spearman is more appropriate. For more, see: stats.stackexchange.com/questions/3730/pearsons-or-spearmans-correlation-with-non-normal-data
Great video! Thank you!!
Thanks, Katie! Glad it was helpful
Thanku very much mam.. I have a question that how we interpreted it in our article. Can you suggest me any Article in which transformed data is shown
I apologize for missing your comment. I do not have an article on hand to suggest. Sorry!
@@virginiawickline2609 ok.. Thanku very much mam for your reply
Mam,Can I get this data sheet what have you used?
Hi Golam, with regrets, no. The dataset is used in my classes and is kept private since they helped fill out the items.
It is so much perfect
So glad this helped!
Stats is so interesitingggggg
Hi Coco - haha. Maybe not - but it is useful! ;)
Thank you very much.
My pleasure! Thanks for checking it out! :)
hi virginia, thanks for your videos, it really helps me, but can you do the example with less data like 3-5 data, but a lot of respect from indonesia🇮🇩
Hi Dopeee, thanks for checking out my videos. I appreciate your comment and need to kindly decline. My videos are primarily designed for students in my class with the dataset we use, so I need to keep the variables shown to help them.
You helped me a lot. Thank you.
Hooray! :)
Thanks for this! Extremely clearly explained (revisiting SPSS for first time in 20 years!)
My pleasure, John! Thanks for checking it out.
Most helpful SPSS guide I've ever watched. So straightforward and explanatory on all the points I usually get confused on.
Thanks for the feedback, Tyler! Happy to be of service.
Hi! What is the best way to plot a spearman correlation so that we clearly see the information that it is giving? I think it's not useful to plot a regression line as it depends on outliers, while the spearman correlation doesn't.
Hi! I sometimes still plot a regression line or a Loess curve to see where the data change directions. I am open to options/suggestions from other viewers!
Thankyou so much
My pleasure :)
Thank you so much for this!
ı have tried all the transformation but still, it did not fixed the positive skew matter. what should we do?? please guide me
Hmm...have you also considered removing outliers (high Cook's D value) or cases with high leverage?
@@virginiawickline2609 is it normal to remove it. I am about to consider this variable as dependent one. It was behaving like poisson but with this behavior it doesn't respect poisson assumption either.
@@phd.eriolamariuscharlotade5634 Hi! You are reaching the limits of my knowledge. However, it is fairly common to remove cases with high Cook's D values so you are removing the influence of outliers. See, for example: towardsdatascience.com/identifying-outliers-in-linear-regression-cooks-distance-9e212e9136a
super helpful
Glad to hear - thanks! :)
The video cut off before you were able to finish.
Oops - sorry! Thanks for the feedback! This segment covers making a continuous (ratio) variable into two chunks (nominal). I will work on shooting a new video very soon for reverse scoring.
NOTE: This video was made before SPSS started calculating effect size (Cohen's d). If you run effect size, use the "point estimate" to determine if the effect is small (.20), medium (.50), or large (>.80). Use the absolute value for Cohen's d (no negative sign).
Excellent 👌 Mam
