Thank you so much, Ma'am! I am having a hard time to understand the Hypothesis Testing since self study lang po ako. Will share this to my classmates po na nahihirapan din. Thank you po!:)
salamat po maam mabuti pa si maam donna na iintindihan ko lahat ng tinuturo nya kaysa sa prop namin na binabasa lang yung solution manual nya salamat po maam sana po gumaga pa po kayo ng madaming video. about statistic
Thank you po ma'am mas nagets ko na po yung about sa one-tailed versus two tailed na part saka dun po sa part ng pag gamit po ng z table. Nalilito po talaga ako sa part na yan tas wala akong mahanap na yt vid po na mas ineexplain po ng maayos kaya thank you po napaka clear nyo po mag explain naintindihan ko po.
I am a future sociologist/ social researcher, so it is very important for me to know how to solve statistics. since I was a chid, numbers are my weakness. but thanks to, Teacher Donna! I've learned a lot from her! thank you so much for sharing your knowledge! God bless and more power!
Thankyou po ma'am, ang laking tulong po nito saming mga students, lalo na po sa katulad kong self study lang. Kanina pa po ako nalilito kung pano gagawin, d ko po magets pag binabasa lang. Naintindihan ko po agad yung turo nyo. Thankyou po😭
Maraming salamat po Ma'am Donna. Di niyo po ako estudyante pero sa dami ng videos na nandito sa yt sainyo po ako mas natututo, sobrang swerte po ng mga estudyante mo sainyo
the problem here is that there is overlapping. pag Ho: M1=M2 ang alternative hypothesis ay either: 1) H1: M1 M2 3) M1 not equal to M2...sa presentation nyo, may nag overlap ang mga equal signs sa Ho and H1. pag Ho: M1=M2, dapat ang H1 ay wlang less than or equal signs
Thank you Ma'am, online exam ko po ngayon sa Advanced Stat. Medyo di ko po na gets yung ibang lessons namin dahil mahina ang signal. Humihinto hinto po everytime na may google meet meeting kami. Ngayon naintindihan ko na po. Salamat po!😉😍
Hello poo! You're giving me the face-to-face vibes and the what-elementary-days-are-like because of the tendering vibes, and it's so nostalgic. Namiss ko po tuloy old method of learning😭😆❣️😢❣️❣️
exercise: A population of 50 bank tellers has a mean salary of php15,000. however, a researcher reports that the average salary of bank tellers in san fernando pampanga has changed and is therefore not equal to php15,000 anymore but is at php13,000 a month. at 95% level of confidence and standard deviation of 1500, test the claim that the bank tellers do not earn php15,000 per month. Pwd po pasagot ma'am, para po malinaw lang . Di ko po kasi magets bakit mali po ako hehe
I beg your pardon, ma'am, but i tried to solve the first example you provided and solved as well and we have different conclusions. Then i thought, you used T-table instead of Z-table which is what we are looking for, and the computation you had solved is completely different from mine. 65000-63000 is 2000 and 5250÷√35 is 41110 and when you divide the whole thing, the answer is 2.2537 which did not fall on the critical region. please kindly clarify if i am the one who is wrong. this video really helped me. thank you very much.
i have this concern for example 2 kasi ang given ay ang standard deviation ng sample at hindi ng population. So hindi appropriate ang z-test to work this out, It should use one sample t-test given that the population sd/variance is not known.
Teacher Donna, first thanks for the good work BUT please explain to me, u said since n is greater or equal to 30, then we use the Z-test. Why do u use the student's t distribution table to get the z- value? Please explain that to me, coz, am fully confused and failing to understand the concept. Thanks, Evans from KYU, UG
Thank you po. May natutunan po ako Ma'am. Kaso destructed ako sa subtitles..huhuhu..nakakadestruct talaga, mali-mali pa cya.. More power po to you and Godbless
Helllo po, galing nyo po magturo. Ngayon ko pa lang mas naintindihan ang statistics. By the way po, what if you have less than an interval? what would be the Ho and Ha?
Blessed day ma'am! I'm not one of your students, pero mas naintindihan ko po yung Z-Test dahil dito sa video niyo po. Looking forward po sa T-Test, same lang po ba yon? But overall thankyouuuu po ma'am. Godbless po sainyo 💛
Paano naman po ma'am kapag hindi nakaspecify yung sig.alpha? Saan po kami magbase. Salamat po, ang galing nyo kasing mag.explain naintendiha ko ang discussion mo.

Medyo magulo. Madaming parts ang magulo ang explnation especially example no.1. How come that the null hypothesis will have a notation or symbol of less than or equal while it was clear in the first explanation of the rule that null hypothesis will only use equal (=) sign and the signs like less than or equal and greater than or equal is for alternative hypothesis.
