Research Designs

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.

Case study

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

Ethnography

participant observation of a culture or distinct social group

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
