Final Answer : True, Explanation :  Difference-in-differences (DiD) is a statistical technique used in econometrics and social sciences to estimate the effect of a treatment or intervention by comparing the average change over time in the outcome variable between a treatment group and a control group. This method helps in identifying causal relationships by controlling for confounding factors that are constant over time.
