DEFINITIONS

Discrete data are restricted to defined separated values with a finite or countable number of different possible values, for example integers or counts.

Continuous data are not restricted to defined separate values, but can occupy any value over a continuous range, for example decimal, rational or real numbers.

SOLUTION

X=pH of water

The pH of water typically takes on values from 0 to 14.

Moreover, the pH can take on decimal values (such as 7.5) and thus the random variable is continuous.

Result:

Continuous.
