What effect would the incomplete drying of a sample (for example, the incomplete removal of a recrystallization solvent) have on the melting point?

The melting point will be lowered and broadened.

Explanation:

The melting point of a substance is the temperature at which the substance changes state from solid to liquid. The incomplete drying of a sample may result in the presence of impurities. There is presence of solid sample in the solution that fails to dry. The solid sample is not fully crystallized from the solvent or any other liquid with which it can form a true solution. The presence of these impurities in a sample for example, the incomplete removal of a recrystallization solvent cause the melting point to both lowered and broadened.
