Verified step by step guidance1
Understand the concept of 'individuals' in a data set: Individuals (or units) are the entities about which data are collected.
Identify what each row or entry in the data set represents. Since the data set records average temperatures and beach access locations for several towns, each entry corresponds to a town.
Recognize that variables are the characteristics or attributes measured for each individual. Here, average temperature and beach access location are variables.
Therefore, the individuals in this data set are the towns themselves, as they are the entities being described by the variables.
Conclude that options like 'number of beaches in each town', 'average temperatures', and 'beach access locations' are variables, not individuals.
