Dr, boleh nak tanya sikit. bagaimana nak kira sampel saiz untuk prevelance study? berdasarkan peratus kajian terdahulu 4.5%. terima kasih Dr.
Rujuk http://drtamil.wordpress.com/2012/09/21/fk6143-how-to-calculate-your-own-sample-size/
Kalau prevalence 4.5%, guna accuracy 2.25% . Look for the Kish formula.
Dr, kami hanya di ajar dlm 1 jam setengah sahaja di dalam kelas ttg tajuk sampel saizni, agak ssh nak fhm. kenapa accuracy 2.25%? prevelance bawah 10%, kena setengah kan nilai tu dalam pengiraan kan? ada tak laman web ttg pengiraan asas sampel saiz ni? terima kasih
Link yg saya beri ada 7 set slide dan satu ebook. Link ebook itu ada bawah slide terakhir. Sila klik. Saya dah demo dlm kelas.
Btw siapa yg ajar? Cuba tanya pengajar itu utk lebih jelas.
terima kasih Dr.
Klik pada perkataan “Free ebook on samplesize by Dr Azmi Mohd Tamil” to view the ebook
Saya daripada kolej luar, bukan pelajar UKM. Saya cuba baca dan faham dulu, terima kasih Dr kerana membantu.
Kalau kolej luar, lebih baik jumpa pengajar anda sendiri. Mungkin “mazhab” statistik berbeza :-), jadi kaedah saya tidak diterimapakai di kolej anda.
