how to tabulate value of z score??? i mean in accordance with variable like how we write it in tabulation that weight have this z-score, hight have this z score, etc etc... because in spss it appears in a looooonnnnng row, and not as single digit equal to your number of observations.... like i made 50 observations on hight and weight, so z score appear 50, and not as single and one entity. how can we change it???? is it the mean z score which you mentioned in video???
Good job!Very helpful and explanatory video..Maybe you could explain that z follows the normal standardised distribution and for this reason has mean equals to zero and s.d equals to one. E(z) = E((x-μ)/σ) = E(x/σ-μ/σ ) = 1/σ Ε(x) - μ/σ = μ/σ - μ/σ = 0 Var(z) = Var((x-μ)/σ) = 1/σ^2 Var(x - μ) = 1/σ^2 [Var(x) - Var(μ)] = 1/σ^2 (σ^2 - 0) = = 1
Good evening, sir, please, how can I compare or evaluate the growth of children by height and weight with reference curves for height and weight at different ages according to the World Health Organization according to z-score
I appreciate this man. Thanks very much. I pray every do great in their statistics class.🙏🏽
Thank you for you video, but how would you go about reporting the results in a result section
Very clearly explained. Thank you. Another great presentation!
THANK YOU VERY MUCH!! YOUR EXPLANATION IS VARY CLEAR AND HELPFUL! BARAKALLAH!

Thank you. This was informative and well explained.
you are a life saver, very clear and concise. thank you so much

This video has been very helpful.
Very good explanation. Thank you!
My pleasure, Bob!
Thank you ver much.
How is Altman Z ratio calculation done?
Can you make a sample application with five arguments?
How do you interpret in APA?
Good job!Very helpful and explanatory video..Maybe you could explain that z follows the normal standardised distribution and for this reason has mean equals to zero and s.d equals to one.
E(z) = E((x-μ)/σ) = E(x/σ-μ/σ ) = 1/σ Ε(x) - μ/σ = μ/σ - μ/σ = 0
Var(z) = Var((x-μ)/σ) = 1/σ^2 Var(x - μ) = 1/σ^2 [Var(x) - Var(μ)] = 1/σ^2 (σ^2 - 0) = = 1
So if all mean zscore .000000 and all std 1.000000 how do i interpret that? Do i say data normally distributed or something similar?
Z score and z test are same??

Did you found a solution please ?
Great job!
Your voice sounds a lot like Joaquin Phoenix's Joker
Thank YOU 🐩
very blurry. You should redo the video.
