This video was a great supplement to the text in helping me understand sampling, normal distributions, and the central limit theorem. Working with Excel and SPSS appears to make analyzing such a large sample size much more manageable.
I felt that this video made statistics and calculating central limit theorem less intimidating for me. I appreciate that the video seemed easy to follow and was explained in a slow-paced manner.
Along with the other people who have commented, I as well have not been exposed to the Central Limit Theorem. It will take me two or three times of watching this video to gain a more clear understanding, but I do understand the significance for it.
I never realized that this theorem was so important to statistics and understanding how they relate to a population or sample. This video was very informative
I have read about the central limit theorem in a textbook; however, I did not understand it as well as I wanted to. The further explanation of this concept through viewing this video has assisted me in understanding a bit more. This video will be a reference point for me to come back to for more insight.
I had never heard about this concept, however, with the examples and comparisons of Excel and SPSS given in the video, I believe i have the basic idea. I will be returning to this video to reference as needed.
I was not familiar with the Central Limit Theorem in either SPSS or Excel. I think the explanation of it was very easy to follow. I liked the examples that were given; it helped me better understand the concept.
As with many of your other videos using SPSS and Excel, this one is helpful for those who are visual learners. I have never understood the concept of the Central Limit Theorem until now. This would be helpful to refer back to when I get confused.
This was such a helpful and useful video. I appreciated the example being used with the different distributions. It's so interesting how excel is able to gather all of this information. This useful is helpful in knowing how to use excel effectively and to have a nice visual to follow along and see how it all should look.
I like the concept behind this histogram and how it can randomly check the sample that is re-created. I also like how you can move the data from normal distribution, exponential and uniform in SPSS into Excel. Once you have the info in SPSS it is easy to cut and paste into the Excel spreadsheet.
Yes, excel and SPSS are pretty easy to use together, once you have the data in the correct format. Its a rally nice feature of both as you wont run into a lot of companies that have SPSS.
I was definitely not familiar with this concept but I did like the comparison between SPSS and Excel. I think this video was a lot to take in all in one shot, so I might need to revisit this another time.
Having never seen SPSS it was nice to see the comparison between it and excel. I can see how using the Central Limit Theorem is important in looking at distribution. This video did lose me a bit in the terms, it is worth a re-watch.
I am not familiar with the Central Limit Theorem, and although this was another useful video, I think I will understand it better once I grasp the concept of this theorem further.
I was not familiar with the Central Limit Theorem, it was interesting to see how the normal distribution and uniform distribution came up so similar and the exponential distribution so different. There were a lot of steps but I see the importance.
Although this was a fairly easy to follow video, I still prefer Excel than SPSS. This was a good review on the Central Limit Theorem and how they are used in Excell and SPSS.
Being able to see the graphs that correspond to the data is helpful, as is visualizing the various distributions in histogram form (normal, exponential, and uniform). Central Limit Theorem is a slightly uncomfortable concept, but the transfer from Excel to SPSS seemed to be straightforward.
I think that this video was helpful in my undertanding of the importance on the Central Limit Theorem to statistics and the ability to make inferences about a population based on a sample. However, i do feel that this was a lot in one video to take in.
+Mandy Moore I do think this video was helpful in understanding the importance on the central limit theorem also, but I was slightly overwhelmed by all the information provided in this video which leaves me to be a little confused on how to actually conduct this.
Very interesting stuff! So we are taking the mean of the random sample groups to create a normal distribution which is basically the Central Limit Theorem?
The Central Limit Theorem states that the mean or sum of repeated samples for any distribution, those mean values are going to approximate a normal distribution.
I like the comparison between SPSS and Excel. It's nice how the histogram displays the random samples. The central limit theorem is still not clear to me though.
When looking at any distribution that will be normal, one can draw a sample several times and their means are approximately normal in uniform or exponential. All comes from the mean of a sample. Seems obvious when done but many steps!
Then why should we check for assumption of normality when with central limit theorem we always get normal distribution even in a non normally distributed population? We always seem to have Normal distribution no matter what....so why even check normality assumption ?
This video provides examples of the central limit theorem, using data to reveal that if tested repeatedly, the distribution would still be of a similar bell-curve shape.
The Central Limit Theorem again tackles the importance of uniform distribution and normality, so that data sets are not subject to over-generalization (internal v. external validity).
While I enjoy seeing how the same concept is executed in both SPSS and Excel I feel like I have no idea what Central Limit Theorem is. I tried to Google it to understand, but still found myself lost on the concept. I think this is something I would like to talk about in class because I did not understand it at all.
+Melissa Clendaniel I agree as I was not familiar with these concepts. I watched it a few times and still have not grasped the differences between the distributions.
This was very hard to follow and I do not have a grasp on what the central limit theorem is. I saw that the graphs in SPSS were all very different and only one a normal distribution but I do not understand what was going on in excel.
+Alicia Zahn I am glad that I am not the only one! I felt completely lost the entire time. I also felt that the Central Limit Theorem was not explained, and if it was, I completely missed it.
+Alicia Zahn I felt lost during the video too. I tried to Google it, but still didn't understand. I think this is something we should go over in class, because the consensus seems to be that it was difficult to get.
This video had a lot of different steps and utilized SPSS and Excel. I felt lost for the majority of the time, honestly. I also do not understand what central limit theorem is.
+Rachel FosterThis video was overwhelming. As I was taking notes, I kept putting a ? beside of everything I wrote down. I could not find VBA so it made it even more confusing for me.
The video was overwhelming and I did not grasp all the numerous steps and formulas. Seeing the graphs of the different distributions, normal, exponential, and uniform, was helpful but I still did not completely understand the differences.
+Michelle Robinson I had trouble with this as well. Altogether I do not grasp what this was demonstrating. I looked up the central limit theorem to see if it would help but that did not help me. This is something I hope we can go over in class.
Yeah, that's theorem is tough to understand. The comparison is good and the video is good, but I had to read about the theorem rather than watching the video. That just seemed to work for me.

Dear Todd Grande, could you make available this Excel sheet? It would be great for us!
It was nice to see the comparisons between SPSS and Excel. The explanation of the Central Limit Theorem was clear and easy to understand.
I have had the luxury of using SPSS and once you learn the flow it is very easy!

Seeing it used in SPSS and Excel was a nice comparison.

Very informative video on the central limit theorem.
Thank you for breaking down very complex information.

This useful is helpful in knowing how to use excel effectively and to have a nice visual to follow along and see how it all should look.
I think I need this broken down in-person. I’m not sure what I was looking for here. I’ll definitely need to watch this a few times.
This video had a lot of information. I like that it showed both excell and SPSS but I will need to watch it a few more times to better understand.

Yet again I cannot thank you enough!!!
I enjoyed seeing both SPSS and Excel. After watching this, I think I would like to become more familiar with SPSS.
Thank you for the detailed explanation. I understand the central limit theorem a little better
More complicated using the SPSS system but still a good video. It's a good guide.
I was definitely not familiar with this concept but I did like the comparison between SPSS and Excel. I think this video was a lot to take in all in one shot, so I might need to revisit this another time.
+Candace Fernandez I agree. I don't fully understand Central Limit Theorem so I definitely need more practice.
Having never seen SPSS it was nice to see the comparison between it and excel. I can see how using the Central Limit Theorem is important in looking at distribution. This video did lose me a bit in the terms, it is worth a re-watch.
This is not a concept that I have clear grasp of. This video was helpful and I will have to refer back to it in the future.

this was very interesting to see how Excel creates graphs from sample data
Interesting, but I would definitely need some time to work with this.

+Ariadna Aguero The concept is still unclear to me, too. I can memorize the terminology but am having a hard time wrapping my head around it/why.
+Ariadna Aguero Agree with you on all of that, especially the comparison.

It was nice to see the differences between excel and SPSS but as many have stated the CLT is still hard to wrap my brain around.

I found this video to be a bit confusing, but I do think having the visuals helped.
The comparison was helpful but this video was much tougher to understand for me.
Still a little confused on this one and had to pause a few times. I think that I'll be re watching this one soon.
Still very confused but I was interested to see how excel created the graphs.
I am not familiar with this concept and feel like this video went over my head. I can see that I will be revisiting this concept

I understand central theorem but with this video I struggled following and understanding what you were doing
This video had a lot of different steps and utilized SPSS and Excel. I felt lost for the majority of the time, honestly. I also do not understand what central limit theorem is.

+Jeff Pincin I agree. Some of these terms I have to read as well to fully grasp what they are and how/why they are used.
SPSS is just excel on steroids😃
