Answer:
It is a discrete variable
Step-by-step explanation:
Discrete data take particular values, while continuous data are not restricted to separate values.
Discrete variable contains a certain number or unique number(like a whole number), a discrete variable is countable and you can know the exact number.
So number of student reading statistics book is a unique number and countable. A continuous number can be a real number e.g(2.3, 5.678) etc
So the statistic student reading book can be 10, 34, 1000, 356, etc
But the statistic student reading the book can't be 1½, 56⅔, 7.6. We can't have two and a half people, it is either 2 or 3 people.
