Question

Determine whether the quantitative variable is discrete or continuous weight of gravel in pile is the variable of gravel in a pile

Answer 1

I will define or explain about discrete and continuous data. Discrete data is the data that can count or data that have finite values or buckets while continuous is the data that cannot count or the data that have infinite number of steps, which form  continuum. In your example, we can include that gravel in pile as a continuous data because we cannot count it just like the sand. The answer is continuous.
