Why each option
A discrete variable is one that can only take on a finite or countable number of distinct values, often whole numbers resulting from counting.
The temperature of a hot tub is a continuous variable, as it can take on any value within a range, including decimals and fractions.
The height of a horse is a continuous variable, as it can be measured to any degree of precision and can take on any value within a range.
The time to complete a task is a continuous variable, as it can be measured to any level of precision, including fractions of seconds.
The number of people in an office is a discrete variable because it can only be represented by whole, countable numbers (e.g., 1, 2, 3) and cannot take on fractional or continuous values.
