Techniques of mindom

Mindomo techniques cover a range of experimental and non-experimental methods aimed at understanding various scientific phenomena. Experimental methods involve manipulating variables under controlled conditions to observe changes, effectively detecting cause-and-effect relationships.

Techniques of mindomo

correlation

limitation
does not tell researchers whether or not the relationship is causal. In other words, correlation does not, cannot, prove causation.
Strengths
etermine if there is a relationship between two variables without having to directly manipulate those variables. moreover, used as a basis for prediction
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
strengths
detects cause-and-effect relationships
manipulating a variable under controlled conditions then observing changes

case study

example
Would a nocturnal (active at night) animal know when it was time to be active even if there where no external indicators of night vs day??
limitations
Descriptive methodInvolves single individuals or few Social science: rely on different information
strength
Gives detailed appropriate view of individual’s lifeSocial science: understand social and familiar factors Natural science: study single animal or instantUseful when experiment can’t be done
Description.
Non-experimentalInvolves in-depth descriptive kept by out observer( individual or group of individuals)Social science this involves collecting, examining..etc (biographical data, medical records,..etc.)Natural science requires detailed investigation

naturalistic observation

strenghts
Behavior can only be described, not explained.
limitaions
allows researchers to observe behavior in the setting in which it normally occurs rather than the artificial and limited setting of the laboratory.
description
observes and records some behavior or phenomenon, sometimes over a prolonged period, in its natural setting.
