Had summer class because of this. Was still confused in summer class. This helped. Then 2 weeks after summer class, I’m back in school. Which is bullshit.
Taking college stats & your teaching is sooo helpful & I can actually understand the material. You are very passionate about statistics & it shows! Thanks:)
I think the teacher uses n instead of -n as the divisor because the problem is for a population, not a sample of a population. That important point should be included in the lesson. The concept is difficult enough without explaining this crucial point.
I have enrolled in Sophomore level (University) statistics, just to drop it, like 4 times, because I knew, before the midterm, that I was not going to be able to pass it. I finally did, with a C. Not my best work. I am an A/B student. Years later, I am back in school for a second degree, and I am having to re-take statistics because the statistics I have credit for is "statistics/business majors" and now I am a pre-nursing student, so they are making me take regular statistics (not for business majors), which I think is ridiculous, considering its the same material, same book, same chapters are covered, but I digress. I had a melt down when I found out I would have to take this class again, especially as it is the last class I have to take to enter nursing school. If I had access to these videos way back when, I could have passed statistics the first time, with an A. I have a A in my class now, and am breezing through, with EASE. This class used to keep me up at night, stressed beyond belief. I am actually enjoying it now. It amazes me, the difference it makes, when you have a GOOD teacher. I cannot thank you enough for your time and effort put into this channel. You have saved me from a guaranteed ulcer.
When you wished that this guy could have been my math teacher when I was in school. Thanks for explaining everything so clearly. Getting ready to take my Math 4-8 certification exam -- I finally get it! Thank you!
I got confused about the square root of 8.69=9.32, I thought my answer is wrong, thanks to the guy who noticed the answer. Anyways thank you, Mr. Brian, your videos are a big help to me.
thank you so much for this video, I had missed this class and didn't know how to do it. with your explanation and visuals I learned it so fast as was able to finish my work all today. you are a god send
I know this video is old but it just saved me I am horrible at math never really understood much in it but the way you did this step by step is easy terms was so helpful and helped me understand what I was actually doing and had to do so thank you!
Wow, thank you so much for clarification of variances for me. I am currently finishing my masters degree and haven't take a statistics class. So this does explain the concept well. Thanks again!
YOU are amazing!!! Do you have more videos?? You just taught me in 8 minutes what Ive been struggling to understand in one whole week.. Stats is my very last class standing between me and my BA and Ive been putting it off for a whole year bc every time I sit to do my homework, I cry.
He is right because he is dealing with total population which is n=10 and we use n-1 where we are drawing sample from the population. For more brief lets take as example If we want to measure height of one class of 15 students and we are taking all the students so it means we are taking whole population (Class of 15 students). Here we use 'n' not 'n-1'. If we want to measure height of one all students in a university which are 1500 students and we are taking only 15 students so it means we are taking sample from whole population. Here we use 'n-1' not 'n'. Hope explanation will assist you.
I was about to go back at the previous minutes of the video, but decided to just finish the whole lesson. Thank goodness it was corrected just a few seconds later.
Maraming salamat po! ❤️ Today is our exam and it was so difficult for me because I'm not really into Math 😭 then finally i understand this way of solving than the examples in textbook. THANKYOU Prof!❤️
Hi Brian. Just tried this method solving variance for nos: 8,8,9,12 ...and I got 2.68 for variance. Did I got the correct answer? Just checking if I did the right solution 😊😊😊
I paused ur video and getting root wrong.. then i started ur video i got the same answer in the laste bcz u took wrong root by mistake.... Sir vry nice teaching method....👍👍👍
Good explanation ... but lots of notation errors. If you're calculating sigma, x-bar should be myoo and n should be N. If you are calculating s, then you should divide by n-1, not n. Some teachers are super picky about notation ... I'd hate for students to lose points for poor notation.
