I gave my students this multiple choice question: A scientist studied the number of eggs a species of bird lays each year. He found that the most common number of eggs laid in a year is three. Which statistical measurement did the scientist find?

Only one answer is correct among these 4 choices:
- the mean number of eggs laid in a year
- the median number of eggs laid in a year
- the mode of the number of eggs laid in a year
- the range of the number of eggs laid in a year

Could you tell me which one is correct?

the mode of the number of eggs laid in a year
