To determine the mode or modes of the ages in the provided data set, we need to identify which age(s) appear most frequently.

Based on the survey results:

  • 14 years old: 15%
  • 15 years old: 50%
  • 16 years old: 20%
  • 17 years old: 15%

The age that has the highest percentage of respondents is 15 years old (50%). Since 15 years old is the only age that appears with the highest frequency, the mode of this data set is:
