instrumental variable designs
Instrumental variable designs refer to research methods in which an instrumental variable is used to overcome potential biases and identify causal relationships between variables. It helps researchers estimate the causal effect of an independent variable on the outcome of interest by using an unrelated variable, the instrumental variable, that affects the independent variable but has no direct effect on the outcome.
