on experimental discriptive method, it measures the relation bet 2 or more variables or behavior

survey

Subtopic

when answering a questions,one's memory can fail him and also the misunderstanding of the question affects the survey

it is useful when having a survey on behavior attitude that can't be observed directly

it is a type of non-experimental study. it is mainly about doing interviews and questionnairs that consists of multiple choice questions and short essays

experimantal

: location of memory in birds

a- only used when it is practical and ethical b-artificial conditions used differ from real nature
