- How to find the P-value when given a test statistic in a t-distribution. This is for when testing claims about a mean, in the case population deviation is unknown (T-Test).
THANK YOU! The whole "use technology" thing always gets me! There's never any further explanation about it!
Yessss like wth
Ohmygods thank you, all I've spent all evening wanting to know if how to find the pval, but everything (including my textbook) makes it seem like the number just magically appears and I must be an idiot for not understanding. So thank you for making it so clear and simple.
I couldn't find anyone that would explain how to find the p-value using t-chart. THANK YOU SO MUCH
10 years later you've helped me comprehend this concept so easily. I truly appreciate it and hope you're doing well.
You sweet angel of life! THANK YOU.
This helped me understand how my teacher arrived at the p-value during a lecture. He just went from one number to the next and I was like ???????
But this video has wiped away all those question marks.
Many thumbs up!!
What if it is two-tailed?
This has been fantastic! I wish my instructor did a lecture. Trying to learn from Sullivan's "Fundamentals of Statistics" with no lecture from the over-paid instructor has been absolutely painful this semester, and just has not made sense. You have no idea how beneficial this has been to me!! Thank you!
Thank you so much... this whole section n hypotheses tests has not be able to be wrapped around my brain and there's a test thursday...with this, I got it! :D please do more!
Home boy you saved my statistics grade in one video Thank you!
thank you so much, you save my life for my midterm because i am having the worse professor in my class!!! Well explained!!!!!
THANK YOU. Exactly what I needed!
this video is the pillar for the comparing two means :
Thanks :)
Really cleared up a lot for me. thanks a bunch!
🙏🏽 wow thanks man great video just saved me
thanks, you helped me before the day of examination. Wish you be happy.
Thank you for your very clear tutorial. I know how to calculate the P-value with my TI-83 calculator now. :)
Thank you for helping with my midterm :)
Been trying to find out the p-value forever using T distribution chart, but it's so off... This saved my life.
these are great ASMR videos
it helps a lot! Thanks!
Thank you so much! I have a final in an hour and 15 minutes and I just blanked on this one thing
I have a test in one hour, this just saved my grade
Thank you so much! -- LSU - Alexandria!
Thank you so much! This helped me incredibly much more than the examples in my book and in the videos. -SLCC, UT
Thanks! I understand now!
That is unusually high...Do you have the hypotheses, though? If you know the hypotheses, you can determine the direction of extreme...If H1 is mu >, then it's right-tailed; if it's mu
THANK YOU SO MUCH FOR THIS VIDEO!!!!! I was lost and almost in tears!! Thank you...been working on this problem for hours. I could not figure out how to find the p-value using a calculator for nothing in this world!!!
very well explained, thank you. you have a nice voice, too :)
Thank you so much!
Thank you very much. You helped me understand the P value. I wish our instructor would teach the same as you do; plus go over the use of TI-83Plus calculator! Awesome job
Really helpfull thank you!
Thank you. very good
Thank you so much sir
why do i feel like youre shaking too much haha thanks man
how about when t is negative
Thank you!
Oh my god, thank you. -Michigan Tech
You just helped me understand this! Thanks so much
i love you
Mark the given t on your t-distribution. If it's positive, shade above it. Then find the area above. Double it because you also have the mirror image tail on the left. If it's negative, shade below it. Then find the area below. Double it because you also have the mirror image on the right...
How do you come, on the TI-84, to .3355? On two different TI-84s, a Plus and a Plus CE-T I come any time on .1645
What if you have a negative t score do you use. -e99?
When using the table, do you round up if you have a t-value of 0.046 for example?
so,we don't get the actual p-value by using table alone?
perfect. this helped me out sooo much
how would you do solve for a two tailed test?
I'm going to cry. We don't use graphing calculators in our stats class, and I cannot for the life of me figure out how to do it on my calculator (TI-30X) or on statcrunch. And we have to give an exact value, not a range! Someone help me
+OzKelsey im just gonna kill myself its a lot easier i did nothing wrong to deserve this! this is like making a person with a heart condition and who is 300lbs over weight compete in a tri-athlon, some people just are smart enough to understand it, its not their fault, just the way we are made!
+TOPGUNCANADA00 Hahahahahahaha well said
+TOPGUNCANADA00 hey but I must have figured it out! I got a b in the class
what about technology for two-tailed
What if the t-stat is coming out to an abnormally large number (after calculation)? say 16.8. And there is no determination of which tail (?)
WHAT IF ITS TWO TAILED
what if we know the p value and we need to know the t value?
I used tcdf(.430, .99999, 24) but I get ~ .171870, how come?
I'll tell you guys something even more evil, in our statistics class, we use R and calculators to calculate things like these, which is fine. However, on the exam, no programming or calculator are allowed, we have to do it by hand and out of the top of our head! GREAT HUH IM SO HAPPY
You didn't show how to use the calculator
I'm not given an "N".. HELP!!!
My questions are nothing like this. "our hypothesis statement is Ho: p= O.4 vs H1: p≠0.4. find the p-value if the test statistic is Zobs= 1.69". That makes no sense to me and I can not find anything on how to do this correctly.
