Explanation:

1. Priya and Han's records are alike in representing birth - months. Priya uses month names and Han uses month numbers.
2. The variable "birth month" produces categorical data. Although Han uses numbers, these numbers are just labels for months and do not have numerical meaning (e.g., we cannot add or subtract months in a meaningful way). They represent distinct categories.

Answer:

1. Alike: Both represent birth - months. Different: Priya uses month names, Han uses month numbers.
2. Categorical data. The numbers used for months are labels and do not have numerical operations applicable in a meaningful way.
