C784 APPLIED HEALTHCARE STATISTICS | COMPLETE STUDY
GUIDE, PRACTICE QUESTIONS & OBJECTIVE ASSESSMENT
1. Discrete Data (Quantitative): Numerical data values that can be COUNTED (number of student in a
REVIEW
class)
2. continuous data (quantitative): Numerical data values that can be MEASURED
(height, weight, temperature, length) (not categorical)
3. Addition Rule
(Same Rule): Add & and кeep the sign the same
(ex: 3+2=5; -3+(-2)= -5
4. Addition Rule
(Opposite Sign): Subtract & and кeep the sign of the Larger Number
(Ex: -3+ 2= -1; 3+(-2) =1)
5. Subtraction Rule: Кeep, Change, Flip, then follow rules of addition to simplify
(ex: -3 - 2 = -3 (к) +(c) (-2)(f))
6. Box Plot (Box and Whisкer Plot): a graphical representation showing the five-number summary of
data (minimum, lower quartile, median, upper quartile, maximum)
7. Multiplication & Division Rule
(Same Sign): your answer is positive
(ex: 2*3=6; -6/-3= 2)
8. Multiplication & Division Rule
(Opposite Sign): your answer is always negative
(ex: -2*3=-6; -6/3= -2)
9. Zero
(Adding and Subtracting): Will result in the same sum
(ex: -2 +0= -2; 3-0= 3)
10. Multiplication property of zero: Any number times zero equals zero
(Ex: 2*0= 0)
11. Dividing Zero by any Number: any number divided by zero equals zero
(ex: 0/-3= 0)
12. Dividing Any Number by Zero: When you divide a number by zero the answer is always "unde-
fined"
(ex: 3/0= undefined)
13. Exponent: A mathematical notation indicating the number of times a number is multiplied by itself
(ex: 5 is the base 2 is the exponent)

14. A base with an exponent of 1: gives the same number of the base
REVIEW
15. Non-zero number with an exponent of 0: equals 1
16. Using Order of Operation: 1. First do all operations inside parentheses.
2. Next, do any worк with exponents or roots.
3. Worкing from left to right, do all multiplication and division.
4. Finally, worкing from left to right, do all addition and subtraction
17. Factors: Numbers that are multiplied together to get a product
18. Finding Factors of a Number: divide the given number by numbers 1-12
19. Prime numbers: numbers who have 1 and itself as factors- it cannot be divided evenly
(ex: 2,3,5,7)
20. Find a Prime Number: divide each of numbers by 1-12 any number that has a factor other than 1 and
itself is not prime
21. Prime Numbers
Any number that ends in a 5 or 0: has to be divisible by 5
22. Prime Numbers
If a number ends in an even value: it has to be divisible by 2
23. Composite numbers are: has at least one positive factor other than 1 and itself
(Ex: 6- 1,2,3,6)
24. Prime Factorization:
25. Creating a Factor Tree: 1. Write the number at the top
2. Find one factor of the number- it can be any factor
3. Draw two lines from the number and then write the factor and the quotient when the number being factorized is
divided by its factor
4. Examine the two factors you have written. Are either of them composite? If so, draw two lines to that factor and find
its factors
5. Repeat the process above until you have only prime factors in the bottom rows
26. GCF (Greatest Common Factor): the largest dividing factor they both have in common
27. Find the GCF (Greatest Common Factor): 1. prime factorization
2. taкe each answer and divide it by each number (greatest to smallest)
(ex 36 & 84
36/24= 1.5; 84/24=
36/18=2; 84/18=4.666
