My data was checked its normality by using SPSS. Then, the results is not normal, so the data was transformed and became normal. To run dependent T-test, should i use the actual data or transformed data?
Helpful video but I have doubts about the calculation at 10:09, is there something wrong? I thought the standard deviation should be calculated 3-(-0.75), not 3-0.75? Plz correct me if I am wrong
Hi! In the manual calculation, you used the 1-tailed, but in DataTab calculation it showed 2-tailed; in this specific case which one should have been used?
Thank you so much for this video¡ I would appreciate to kwow if Is 0.975 in the t.value table the only column I will always go? If the answer is NO, How going to the right column of the table works? How do I know what is the right column?
Suppose people's weight would drop to zero. You'd get a huge minus for your t. And it would be less than the positive critical value. You'd conclude there is no impact! Something is missing here. Maybe an absolute value?
Ma'am, we can call this example as paired t test , right 2nd unidirectional means one tail test or one tail n two tail term describes something different 🤲 🙏🙏🤲🤲Allah bless you
I was looking for a video to refer my students to watch. There is an error at 9:34 - the std. dev is calculated as 5.84 and then the std. error is calculated as 5.68/2.

I'm feeling like there is something wrong too. I keep getting 5.94 when doing the calculations, not 5.84.
I was very pleased with your beautiful explanation. Thank you, teacher 🌹
WOW!!! I am currently working on research and this information is a life saver😀!!
Thank you, this was super helpful

2 tailed one
How to Calculate Livelihood status of organic and inorganic growers..means does it comes under Dependent t test or independent t test.. please answer
I would say independent t-test, it is an independent sample right?
when doing the calculation for SD i have no idea what I'm getting wrong. I keept getting 5.94 as the SD. Where did i go wrong?
Perfect! You are the best!!!
Wow, thanks!

Hello, 0.975 is the area below the curve. THis corrensponds to a two tailed p-Value of 0.05. Further you need the degree of freedom! Regards, Hannah
@@datatab Thank you so much 💜 God bless you!
@@datatab what about one-tailed test which column do i have to look at
what is Test Value in one sample t test. I have licensed Datatab where it is asking test value when performing the test
Thank you
at 10:56 df 5-1 = 3?
Thank u so much.
Thanks for your feedback!!! Regards Hannah
Thank you!!

Thank you for your feedback! Yes, that's right, that's why you always take the amount or check the sign!
Thank you🛐🛐
Thanks! Regards Hannah!

Thanks! yes a paired t test is the same!!!! Each t test can be either one-sided or two-sided!

Oh many many thanks!!!!
@@datatab So which is the correct answer: 5.84 or 5.68?
Sehr gut erklärt / Very well explained. Thank you for this video:)
Danke : )
