Thank you sir, you helped me a lot.

[@mathandlanguagebyjamesjuni]

You're most welcome. Thank you also for viewing my channel :)

[@gelverjeffcantal2988]

sir what is parameter po..sana masagot exam na namin later

[@kimberlyrobledo5022]

Sir, how to determine the degree of freedom po ba? I've been searching here in youtube since this morning but still can't get it:(((

[@mathandlanguagebyjamesjuni]

Hi Kimberly,
Df= n-1
where n is the number of sample
Check 15:30

[@jupiterc.magsipoc3638]

Good evening po sir, how about pag wala pong decrease of freedom how fo get critical value?

[@mathandlanguagebyjamesjuni]

Kung wala iyong "df", pede mo siya ma calculate sa sample size or sa ibang data.
1. For a single sample t-test:
df=n−1
where
n is the sample size.
2. For an independent two-sample t-test:
df = n1+n2-2
where n1 and n2 are the sizes of the two samples
3. For a paired sample t-test
df= n-1
where n is the number of pairs.

Sir paano po kapag yung given is s²?

[@mathandlanguagebyjamesjuni]

Para makuha value ni "s", kunin mo iyong square root ng "s²"

[@shailayanguas]

Ano pong calculator, iba po kasi lumalabas saakin

[@mathandlanguagebyjamesjuni]

Kahit anung calcu naman, kaso kapag ganito kasi kahit simpleng calcu pede na, mano mano nga lang, tapos as much as possible huwag ka maground off kapag hindi pa final answer.
Kapag normal calculator, ilagay mo lahat ng decimal muna

Good morning Sir. Sir paano po malalaman kung aling significant level ang gagamitin?

[@mariadianacarullo4150]

Nag conduct po kasi kami ng research at gumamit ng pretest and post test. Tapos po we're going to use ttest and t table para ma check yung hypothesis pero di po namin alam ang gagamiting significant level.

[@mathandlanguagebyjamesjuni]

Usually given naman siya sa problem. The lower the level of significance, the more accurate siya. Pede rin ibigay sa problem is confidence level.
So for example, 1.) At a 95% confidence level, then iyong level of significance will be 5% or 0.05
Solution: 95% --> 0.95
1-0.95= 0.05

Thank you so much Sir
