Answer:

Quasi-experimental research design

Explanation:

A quasi-experimental research design is similar to an experimental research design. It involves the manipulation of an independent variable but without the random assignation of participants to groups. Maria's experiment manipulates the administration of calcium, but the participants are not randomly assigned to the age groups, as they are already five or ten years old before the experiment and thus cannot be randomly assigned.
