Several students tested plant growth for given conditions. Which student’s data is most representative of average plant growth for the tested conditions? Alicia tested 6 plants. Brenden tested 24 plants. Caitlin tested 3 plants. Diego tested 12 plants.

A larger sample usually gives a more reliable estimate of average plant growth because it reduces the influence of unusual results. Brenden tested 24 plants, more than Alicia’s 6, Caitlin’s 3, or Diego’s 12, so his data is most representative.
