I bought the statistic course and oh my god every one hour spent watching them is like the best hour of my life this guy knows what he is talking about i cant thank him enough without him i would still be lost and confused god bless you
Thanks a million! At first I was thinking to write down that you have the most suitable voice for teaching. After I saw how much sense everything makes for me I believe that it would have been a shame if you wouldn't have been teaching. Best of luck!
Thank you for your beautiful clarity. My interest in life is poetry, you bring out the poetry in mathematics. You actually, unlike a lot of renters, make a difference in the world. Bravo!
All youtubers are saying the normal distribution is a bell shaped distribution But no body explains like you with the watermelon example,I understand the normal distribution with the help of that example ----- I like ur teaching Thank u Sir U r the best lecturer ----- U r awesome
Hey There..…! I Am From Bangladesh... And I Would Like To Say That This Video nd The Professor Is Superb... I Mean He Delivers The Speech In Such a Tremendous Way....! Keep It Up Sir...! ❤ These Help us a lot to study more nd to understand the Statistics in a Beautiful Way......! ❤❤
For all those who do not understand why the area under the curve is 1: the sum of all probabilities for a sample is equal to one. For example if there is a box with blue and green and red balls and the probability of getting the respective colored balls are denoted as P(green), P(red), P(blue). The sum of their probabilities will always be equal to one. i.e. P(green)+P(red)+P(blue) = 1 The only difference between the above example and the watermelon example is that this example is a discrete distribution while the length of the watermelon is a continuous distribution. Hope this helps
Yes that was a question I needed to understand, the onset for that is when you have to understand when the equation asks for the value to be minused from 1 or not, I am still trying to get to that stage. But thanks for the explanation.
I really appreciate your clarity on how you explain. Please do not assume that we know. Every step is important to those of us who do not know a thing about statistics.
His name is Jason Gibson he used to work at NASA up until 2009 when he started to make online courses. If you want more in-depth videos you can check out his site and buy his courses.
Text book jargon explained in a way that anyone can understand it. Awesome! Why couldn't they do it this way in the first place??? (I'm getting very annoyed with the way they generally 'teach' math and statistics! No wonder people hate it.)
I'm a working professional. Performing as deputy manager in Morris Garages India. This guy's videos have helped me understand the concept and crack the interviews. Thank you sir. You are awesome. Love from INDIA
Thank you so much, I am in mid forties and I am just getting a hang of these concept because my job now requires that I apply them. Just know that you are helping strangers out there.
Hats off! I have been browsing through video after video on RU-vid to understand what this means, most professors took a mathematical approach to explain it. You explained it through plain and simple logic - exactly what a non-math student like me needs. Thank you so much.
Took Statistics 28 years ago from a guy just like this🙏 warned folks back then that 80% of mathematics is studying the college schedule and researching your instructors! I got a 3.9 in that class and the folks in the other class averaged a 2.4 from the PowerPoint professor👍🏾
This man is AWESOME!!! I wish I'd met him years ago! I love viewing his videos and I truly learn something everytime I view this great teacher. I wish there were a way to ask questions and get answers from him.
Can someone tell me how to design a bell shaped curve using a sample from past winning lotto numbers? For example, in the Indiana HOOSIER LOTTERY I graphed each of the 5 columns of past winning numbers for the CASH 5 game going back a couple of years. Let's just look at the first column. The MAX number that won is 28 and of course the min is 1. So, the range is 27. Wouldn't it be easier to analyze each column separately like that instead of trying to figure out the winning picks of all 6 numbers as a whole? (CASH 5 has numbers) How can I make a bell shaped curve with 1/28th increments with, say, 14 as the mean, and how do I interpret it?
Also, How does one make predictions from this? I've been using Excel 2013 and my TI-83 calculator to calculate mean, trend, median, mode, max, min, range, q1, q3, , variance, st.dev, skew, and kurtosis, of each column of numbers ... now I'm trying to learn how to calculate Z scores and apply this info to making predictions for each column of numbers separately. Since they didn't even have computers and calculators when I was in high school, (I remember when out high school bought their first electric typewriter), I watched RU-vid VIDS to teach me how to use the Ti 83 calculator and EXCEL 2013 to do statistics. I need some help with the afore mentioned. ident2twin@aol.com
You make learning math easy and fun. Some of the concepts I learned over fifty years ago are coming back, just by watching your videos. Algerbra and statistics for example. Great job. I love the way you bring the concepts of the subject down to a level that's easy to understand for those who haven't seen them for a while. Another point is the way you will explain concepts learned back in elementary school. Again, excellent job.
What makes this a normal *PROBABILITY* distribution? Probability is usually a number between 0 and 1 and the graph he draws is just a distribution of the data points, not an actual decimal/fraction between 0 and 1. Why is probability in the name of this distribution?
i dont have words to praise you sir....this is magic, after loke wartching 100s of vdos on youtube......finally i got hold of Bell Curve........HATS OFF
Wait, I don't see how the statement from 7:24 to 7:35 is necessarily true. ("By definition, a large part of the population is going to be around the mean"). Say for example you have a set of objects, almost all of which are 20" but it's a known fact that every one in a million is, like, 5 miles or something enormous. That one in a million will make the MEAN value way higher than 20", won't it?
Please help: 4. Bone density can be measured using a DEXA test. Bone density for a 25-year-old woman is normally-distributed with a mean of 956 g/cm2 and a standard deviation of 5.52 g/cm2. Let X be the bone density of a randomly selected 25-year-old woman in g/cm2.
relative measures or how do you call that in English ... about structure, coordination, dynamics, intensity, planning ... do you have a longer explanation of those ... seems simple, but your essential way to see is useful ... I am not a paying customer, yet you are ... deep well
Normal / bell distributions look like bells, never meet the x-axis and are defined by the Mean and the Standard Deviation. At 11:02 the teacher says, the mean decides where the peak of the bell would be placed along the x-axis and the Standard Deviation determines how fat or thin would the bell be.
