Charlotte's investigation of adolescents' friendships involves sampling students from five high schools of varying sizes, which would help to ensure a representative sample. The other options may be biased as they only include certain groups (middle-class moms, divorced men, hospitalized seniors) and may not be representative of the overall population.
