Final answer:

The experimental design lacks random assignment, impacting the validity of the results.


Explanation:

The problem with this experimental design is that the experiment does not include random assignment, which is essential to ensure that participants are equally distributed between the conditions, minimizing the influence of confounding variables.Random assignment helps create initial equivalence among participants, allowing for more accurate conclusions about the effects of the independent variable on the dependent variable.
