me: pastu risau the number of samples yg patut kita amik

kalau kita nak infer kepada malaysian population...kena la amik at least kat north east west and south kan???

kalau saya nak senang wat population dia klang valley kan kak?

atiejay: well...actuallynye kalau yang macam cian dalam engineering ni, quantity sample x begitu penting, quality sample penting i.e. saper yang ditanya, kawasan/lokasi, input

me: akak rasa berapa number of samples yg perlu eh? or camne nak decide on the no. of samples?

atiejay: haah...

atiejay: well kalau nak buat satu malaysia; penduduk mesia adults yang drive katakan 20 juta; so tgk kawasan penempatan + jalan raya; so dalam 4000 ke 5000 acamni..tetapi ni x reasonable kan so kecilkan scope kepada acam cian cakap lembah klng so dalam 500 acamni max

me: 500 ek...bnyk jugak tuh

kena la berdiri buat muke sardin kat pump station eh

he he he

atiejay: itu maximum, dia ada calculation dier

hehehehhe

me: calculation dia?

atiejay: maksunya acamni

me: kat sini ...well setakat yg saya baca...utk pilot test...no. of items + 1

atiejay: haaahhh...itu pilot test kan

ni yang betul2nya..so roughly

atiejay: dalam 5% of the total population but u have to decide the sampling first i.e. kene categorise kan aper jenis driver yang cian nak, seme2 ni balik semula kepada research questions

atiejay: pada kak jojo, cian x yah risau pasal no of respondents tu sebab cian bukan buat social sciences kan..the main product is the system or programme or designs untuk kete kan?

me: aah kan

atiejay: questionnaires tu untuk guide dalam design jer nanti, as a framework

me: i think so...memang not the main issue in the research ...tapi kena jugak careful so that people tak question about the reliability n validity dia kot???

ok ok

me: yes...so main thing...my number of samples about 500...??? drivers of basically passenger cars? and age of cars tuh between 1990's onward kot ek??? ok ke?

atiejay: sebab tu kiter kene pikirkan aper limitations research kita ni...mungkin dari pilot test cian buleh agak orang mana drive keter yang macam mana dan siapa yang drive yang keter yang macam mana kan..kan..kalau ikut hypothesis mestilah keter mahal yang dipandu oleh orang kaya akan mempunyai design yang mantap, but again this is just the hypo, melalui experimentslah kita akan dapat buktikan hypo tu betul ker x

me: and because i want to see gender difference..maybe must have equal numbers of girlie n boys???

atiejay: ok..ok..yang penting cian buleh justifykan kenapa pilih yang acamtu

not really gender x perlu sama banyak sebab tgk population and sampling, saper paling banyak drive di mesia?

me: ooooo tak yah sama bnyk ek.....buku ni aah cakap kene equal...maybe more or less kot...maksudnye tokleh sikit sgt ek...kalau 500 tu 100++ women pun takper kot ek...atleast 200 acamtu ek ....sifu ni memang best....tenkiu tenkiu and sorry kacau akak pagi2 (time mesia..kekekek)

atiejay: ekekkeke..x per...kita ni pun masih belajarkan..so sama2lah menolong
