Question 25

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

Integer data is represented by whole numbers without any fractional parts, and the number of baseball games in a season fits this definition perfectly.

A) Whether a bank account has money

This option is incorrect because it represents a binary state (having money or not) rather than a numerical value. It does not provide a quantifiable integer but rather a yes/no condition.

B) The number of baseball games in a season

This option is correct as it quantifies a countable quantity, specifically the total number of games, which is always a whole number. It directly exemplifies how integer data is utilized in databases for counting occurrences.

C) A single keystroke from a keyboard

This choice is incorrect because a keystroke represents an action rather than a numerical quantity. While it could potentially be represented by an ASCII code, it is not inherently an integer value itself.

D) An approximation of π as 3.14159

This option is incorrect because π is a non-integer value, representing a constant that cannot be expressed as a whole number. The presence of decimal points indicates that this option does not qualify as integer data.

Conclusion

The correct answer, B, is definitively right since it directly represents a count of items, which is the essence of integer data. All other options either present non-numeric states or values that fail to meet the criteria of being a whole number, proving them incorrect in the context of integer data types.
