Correlation

is not causation.

Ethnography

: participant observation of a culture or distinct social group.

Correlation

is not causation.

Ethnography

: participant observation of a culture or distinct social group.

Strength

: the closer the number is to +1 or- 1, the more strongly related the variables.

Experimental design

: investigates cause and effect relationships.

Longitudinal design

: gathers data from one group of individuals at several points of time.

Correlation coefficient

: a number from- 1 to +1 that indicates the strength and direction of the relationship between variables.

Case study

: brings together wide range of information on single individual or group, including interviews, observations, or test scores.

Direction

: the sign +-/of the correlation coefficient indicates the of the relationship.

Dependent variable

: the variable being measured.

Positive correlation

: the variables move in the same direction.

Negative correlation

: the variables move in opposite directions.

Ethnography

Correlational research

researchers gather information and look at the relationship between 2 more naturally occurring characteristics, behaviors, or ideas (ie variables)

Correlation coefficient

a number from -1 to +1 that indicates the strength and direction of the relationship between variables

Strength

the closer the number is to +1 or -1, the more strongly related the variables

Positive correlation

the variables move in the same direction

Negative correlation

the variables move in opposite directions

Experimental design

investigates cause and effect relationships

Independent variable

the variable the investigator expects to cause changes in another variable

Dependent variable

the variable being measured

Longitudinal design

gathers data from one group of individuals at several points of time
