Tipe penelitian eksperimen

Random sampling (teknik sampling random) vs Random sampling (teknik sampling random) vs. Random assignment (randomisasi partisipan ke dalam kelompok eksperimen) http://www.bindichen.co.uk/post/Notes/data-analysis-and-statistical-inference/experimental-design-and-random-sample-assignment.html

Random sampling = Random selection Random assignment = Random allocation Baseline level setara: Setara dalam individual differences/trait. Reduksi allocation bias. Random sampling = Random selection

You can't kid a child! Dalam sebuah eksperimen, anak dari dua kelompok usia (15 dan 18 bulan) diminta menyaksikan dua buah skenario reaksi emosional. Skenario 1 (aktor menampilkan ekspresi sedih saat diberi mainan), skenario 2 (aktor menampilkan ekspresi kesakitan saat berpura-pura melukai jarinya). Reaksi empati yang diperlihatkan anak terhadap masing-masing skenario diukur berdasarkan lama anak mengobservasi wajah aktor (dalam detik) dan berapa kali anak menengok pada pengasuhnya. http://www.dailymail.co.uk/sciencetech/article-2465282/You-kid-child-Even-18-month-olds-tell-person-faking-emotions.html
