Mean & Variance of the Sampling Distribution of the Sample Means

This video lesson is about computing the mean and the variance of the sampling distribution of the sample means.
Happy learning!

Great video! You did a great job of explaining this concept

[@ぱtちいカラフル]

nice vid po!, altho tanong lang, kapag nagcompute sa step 6 and 7 po, naka round off po palagi sa 4 decimal places po? or puwede po 2 or 3 decimal places lang po

[@CrisCruz25]

Pwede naman, however, more decimal places means more accurate results 🙂

[@marchie2496]

maam yung sa step 7 po sa o.1(o.4489) bat ang answer nyo 0.0449? na ang tamang answer po dyan eh 0.04489? no pong nangyari nalito po kasi ako? :)

[@CrisCruz25]

nak, naka-round off lang sa 4 decimal places :)

[@michellemaymorales7716]

mam bakit po naging 5 sa N na malaki

[@CrisCruz25]

Kasi po may 5 values... 3, 5, 2, 4, 6

Pano po kapag may point sa pag solve for the mean of the population?

[@CrisCruz25]

Just follow the process, kahit may decimal 😊

[@tobeythegoat6735]

@@CrisCruz25 I mean pano po kapag yung sagot ay may decimal?☺️ Ito po yung problem ko = 18+22+25+28+32+36 divided by 6 = 161÷6 = 26.83 Isasama pa po ba yung .83? please po I need to know 😭

[@CrisCruz25]

Yes, walang problem isama ang decimals :)

Hello maam paano gawin ang step 4?di ko ma gets po

[@CrisCruz25]

Step 4: List all possible samples and compute their corresponding means. Example in the video: {3,5,2} then get the mean, (3+5+2)/3= 3.33

Maam kung wala po yung n paano mopo siya makukuha?

[@kimnacuspag7082]

Meron po kaseng mga problem na walang n maam tulad po neto. please refer to the problem below. A population of a certain LGBTQ+ community is consists of six (6) measurements 2, 3, 6, 9, 11, and 5.

[@CrisCruz25]

Ano po ang pinapa-solve?

[@kimnacuspag7082]

@@CrisCruz25 Maam eto po yung mga questions 1.What is the mean of the population? 2.What is the variance of the population? 3.What is the mean 𝑥̅ of the sampling distribution of the sample mean? 4.What is the variance of the sampling distribution of the sample mean?

[@CrisCruz25]

@@kimnacuspag7082 You can solve 1 and 2 using the formulas. You have to know the value of n to solve 3 and 4.

bakit 3 ang sample size po?

[@CrisCruz25]

hi 🙂 the problem states "suppose three sections were selected"
