Hello and welcome! I'm a professor at the University of Denver and I make RU-vid videos about psychology, statistics/research methods, and generally interesting things. Enjoy!
I think I would be hanging in your channel for the next four years, Professor. I am taking a BS in Psychology, and I will be looking forward for more concise lectures. :))
I get it now. He was switts yeah if you swiss you, gotta worry, those fuckers want everybody to be under your thumb and slave is look at them watch out.
what is it when you have to study a subject for a test, but you really enjoy learning the material? Is there a 'mixed motivation' term? Or is it more of a spectrum, where you rate a 5 on the Extrinsic (1)-Intrinsic (10) scale?
the symbol you're talking about (μ) is spelled "mu" (mew). it stands for the population mean, whereas x̄ (x bar) stands for the sample mean. as explained in the video, the lowercase sigma (σ) stands for the population standard deviation, not the mean.
My thinking is that if he steals the drug, he just helps his wife to live, but everyone else still has to pay a higher price. If he returns to society (where people also value his wife's right to live above ownership of money, because they donated to help her) and he enlists their aid in regulating drug pricing, then everyone gets the drug at a fair price and gets to live, not just the wife. People have a right to live, if possible, and people have a duty to aid others at risk of dying. No one has a unilateral right to set a price, even in crude capitalism. The market sets the price, certainly not the inventor or discoverer alone. Money does not have value without other people. It negotiates relationships. I'll bet I could talk that druggist into a fair price. 😂
Hello, can I translate your text into Portuguese and post it on the Instagram of the academic group at the college where I study? I will give credits and video link other question , in humanistic psychologic has 4 or 3 principles ?? do you have book about humanistic for indicate?
The example of change blindness when the person was switched out I would have noticed but my husband wouldn't have. I'm a super recognizer while my husband is face blind.
I know this video was like 5 years ago but I'm so grateful I came across your videos, it really helps a lot with how simplified it is than how I'm learning it in class. My teacher doesn't explain the concept all too well in my opinion and it's really hard to understand him in both ways. His way of teaching and the vernacular which I don't understand all too well yet. I can't simply ask him to recommend me a text book for me to study cuz that's another pressure on me again. So really thank you! I'm so upset how I can't even understand the things in class that I enrolled for..
구글- 한글 번역기 잘못인가 봅니다. 당신의 설명은 잘 들었어요.나는 정확한 차이를 알게 되어 기쁩니다. 그렇다면 제목 번역은 아마도 고정관념- 믿음(어느 집단 대부분 구성원 다 그렇다고 여기는 생각의 잣대, 기준)-stereotype *선입견(미리 가지는 생각으로 인해, 겉으로 보이는 자세, 태도 - 편견 no)-prejudice 차별대우(차이 나도록 유독 나쁘게 구분하는 행위 )-discrimination
Im sorry how did you get x- bar ? If is sum of numbers of extraversion is gonna be 192 divided by x-index (Xi) is 19.2 if i get the standard deviations or the (X-Xbar)² is gonna be 19.84 , im still be confused what happen , either im wrong 😭
SIr, you are a life saver! I am Psychology major and will be taking Probability and Stats next month for Fall Semester. This video has helped me to better understand this course!
Could u link to something (or give keywords to search with) that explains why is it better to square than use the absolute value to get rid of the negative? ^^
Pub Med is no longer a reliable source of research. Far too many ill funded "studies". Particularly in the arena of wireless radiation dangers. There are some telling the truth and some not. Wifi poses the greatest threat to human health that humanity has ever faced. I have lived this for 15 years, in addition to being in contact with thousands of people whose lives are now thoroughly ruined over it b/c they can't go anywhere in society anymore. Can't work, can't go back to school, can't get on a plane to visit family, etc. My symptoms are crushed blood pressure, badly burning skin, nervous system damage that is not unlike Parkinsons though the diagnosis says it's not Parkinsons, a total inability to think in the presence of any wifi sources. I feel perfect as soon as I'm totally away from it all. I've tested it out every single day of my life for the past 15 years. It is ALWAYS wifi that makes me have all these symptoms. It started after going to an airport to fly home for the holidays where tens of thousands of people were all in the airport on cell phones and laptops. I was in perfect health before that flight. By the time I got home I was limping, could no longer control my bladder, I could barely see, or think. That week I developed a nervous system issue that keeps me up at night if I don't do 5 different laborious things to keep the symptoms away, but always has to include getting away from wifi. It's RUINED my life.
How can I calculate the sample variances (such as in this example) without writing down so many long ass decimal values? It's easy in the tutorial you have for calculating variances, but there the mean is 2.56, which is no problem to write down manually each time.. But here the mean of Item 1 is 4,42857142857 which is a pain in the ass to punch into the calculator to calculate each deviation from the mean. Ofc I can just type in (31/7), which is easier, but I still would have to write down each squared deviation which is also a long ass decimal number... And I'd have to do this many times over the course of calculating the Cronbach's Alpha :/ Any tips on how to make the process faster / easier? I'm studying for psychology entrance exam and the calculator we can use in the exam is like this: www.helsinki.fi/assets/drupal/styles/16_10_xl/s3/media-image/digitaalisen_valintakoej%C3%A4rjestelm%C3%A4n_laskin_0.png.webp?itok=bgO7Am5i
Will I just have to rely on rounding? And if so, when to round (at every step that yields long decimal values? avoid rounding as much as possible?) and is there a rule of thumb about how many decimals should I include when rounding numbers? Or is there some calculator witchcraft that I can use to calculate this with exact numbers and reasonable effort?
I got 7,28 for the variance of Item 1 when I rounded to 2 decimals in every stage.. Other variances were the same as yours. When I recalculated Item 1 variance without rounding before the squaring, I got 7.29 too... But the final solution was basically the same.. (0,94106... with Item 1 variance of 7,29 vs. 0,94136... at Item 1 variance of 7,28) Soo how should I deal with the rounding? ='D
