Jika dalam
penelitian kualitatif, instrumen penelitian adalah penelitinya sendiri, maka
dalam penelitian kuantitatif, instrumen harus dibuat dan menjadi perangkat yang
"independent" dari peneliti. Peneliti harus mampu membuat
instrumen sebagus mungkin, apapun instrumen itu.
Semua
instrumen (baik yang tes maupun non tes) harus memiliki dua syarat yaitu
reliabel dan valid. Reliabel berarti hasil pengukuran konsisten dari waktu ke
waktu. Valid berarti instrumen secara akurat mengukur objek yang harus diukur. Reliabilitas mempunyai dua dimensi
yaitu Stabilitas dan Konsistensi. Stabilitas mengacu pada kemampuan instrumen
untuk menghasilkan data yang sama dari waktu ke waktu (dengan asumsi objek yang
diukur tidak berubah). Konsistensi tercapai
jika semua item dalam instrumen mengukur satu hal yang sama. Jika terdapat 10
pertanyaan tentang motivasi, maka ke 10 pertanyaan itu mengukur hal yang sama
(motivasi). Selain itu instrumen yang baik juga harus valid. Ada beberapa macam
validitas yaitu contruc validity, content validity, dan faced
validity. Lebih lengkap silahkan download di sini.

BalasHapusYou should see how my associate Wesley Virgin's autobiography launches with this SHOCKING and controversial video.
BalasHapusAs a matter of fact, Wesley was in the army-and shortly after leaving-he found hidden, "MIND CONTROL" tactics that the government and others used to get anything they want.
As it turns out, these are the same methods many famous people (notably those who "became famous out of nowhere") and elite business people used to become wealthy and famous.
You probably know how you use only 10% of your brain.
That's mostly because most of your brainpower is UNCONSCIOUS.
Perhaps that conversation has even taken place INSIDE OF YOUR own brain... as it did in my good friend Wesley Virgin's brain about seven years back, while riding an unlicensed, trash bucket of a car with a suspended driver's license and $3 on his banking card.
"I'm very frustrated with going through life paycheck to paycheck! Why can't I become successful?"
You've taken part in those conversations, am I right?
Your very own success story is waiting to start. All you have to do is in YOURSELF.
