In the following table, indicate whether the researcher in the scenario is collecting experimental data or observational data. Experimental Observational Scenario Data Data A sociologist conducts interviews with former protestors and activists in order to study the struggles of the civil rights movement. A pediatrician randomly assigns babies to two different groups, giving one group a new type of infant formula and the other group conventional formula, in order to study the effects of the new formula. An oncologist randomly assigns rats into two groups, giving one group a new drug intended to fight cancer and giving the other group a placebo, in order to study the effects of the new drug. The issue of confounding variables is more likely to be present in V data sets than in v data sets
