Question 15

The number of baseball games in a season is an example of integer data.

Integer data refers to whole numbers without any decimal or fractional component. The number of baseball games in a season is a countable quantity that can only take on whole number values, making it a clear example of this data type.

A) An approximation of π as 3.14159

This option represents a floating-point number, as π is not a whole number but an irrational number that cannot be precisely expressed as an integer. Therefore, it does not qualify as an example of integer data.

B) Whether a bank account does or does not have money in it

This option is a binary value, often represented as true/false or 1/0, which does not fall within the integer data type. While it represents a decision or state, it does not provide a countable whole number.

C) The number of baseball games in a season

This option is correct since it explicitly refers to a countable quantity that can only be expressed as a whole number, thereby fitting the definition of integer data perfectly.

D) A single keystroke from a standard keyboard

This option does not represent an integer value, as it refers to a character or action rather than a numerical count. Keystrokes can vary widely and are not confined to whole numbers.

Conclusion

The correct answer, C, is definitively the only option that represents integer data, as it is a countable whole number. Options A, B, and D fail to meet the criteria for integer data, either by representing non-integer values or not being numerical at all. Thus, C is the only valid example of integer data in this context.
