Field Studies and Surveys (Schwab, 2005)

Question 1

Time series

Answer 1

Design to investigate longitudinal changes in a dependent variable; independent and dependent variables are measured more than once over time. Less widely used.

Question 2

Instantaneous models

Answer 2

Time series model in which changes in the independent and dependent variables are assumed to occur without an intervening time interval.

Question 3

Lagged models

Answer 3

Time series model in which changes in the independent variable are assumed to take some time to influence the dependent variable.

Question 4

Panel studies

Answer 4

Independent and dependent variables are measured two or more times on a group of cases; design to measure changes in the dependent variable as a function of changes in an independent variable(s).
