No, discrete data cannot have decimals. Discrete data refers to countable values that are distinct and separate from one another. These values are often whole numbers, such as counts of items or categories. For example, the number of students in a classroom or the number of cars in a parking lot are examples of discrete data. Since discrete data is represented as specific counts, it does not include fractional or decimal parts.
To further clarify, imagine you are counting the number of apples in a basket. You can have 1 apple, 2 apples, or 3 apples, but you cannot have 2.5 apples in this context. The concept of discrete data is rooted in the idea of individual units that cannot be divided into smaller parts. Thus, decimals or fractions would not apply, as they imply a continuous measure rather than a finite count.
