WGU APPLIED HEALTHCARE STATISTICS EXAM QUESTIONS
AND ANSWERS
Rational numbers - CORRECT ANSWER✅✅Largest number system
Rational numbers - CORRECT ANSWER✅✅Can be expressed as a fraction. 4 = 4/1. Also decimals that
end or continue forever repeating.
Real numbers - CORRECT ANSWER✅✅Any number; Include zero, negative and positive integers.
Real numbers are considered this. - CORRECT ANSWER✅✅continuous and can be measured.
Discrete data - CORRECT ANSWER✅✅counted; doesn't allow for values between.
Every positive whole number has two square roots. - CORRECT ANSWER✅✅True
Identity Property - CORRECT ANSWER✅✅Property that 0 can be added to any number without
changing the value of the number. Likewise, 1 can be multiplied by any number without changing the
value of that number.
Factor - CORRECT ANSWER✅✅An integer that divides another integer. We say an integer, x, is a factor

or unknown quantity.
cross multiplying - CORRECT ANSWER✅✅method used to prove that a proportion is true.
rate - CORRECT ANSWER✅✅ratio that compares two quantities having different units of measure.
unit multiplier - CORRECT ANSWER✅✅fraction that contains two equivalent quantities but in two
different units, used in order to convert units.
