PART 1 Flashcards
Used to describe the distribution of the variable of interest
- Takes appropriate descriptive statistics to determine the type of data analyzed
- If the intent is to describe how often and event occurs then rates and proportions are used
DESCRIPTIVE STATISTICS
Part or number considered in comparative relation to a whole. Usually in the form of a percentage
EX: 60% of classes performed at or above a B in the class
EX: Percent of Occupancy
Proportion
Quantity amount or degree of something measured per unit of something else. Ratio between to related variables or quantities. Always going to have a numerator and denominator it’s going to be in the form of a percentage
Rate
The mathematical expectation of the average.
- Like the central value
- Hospital uses this everyday
EX: Average length of stay, average discharges per month, average daily census
Mean
Denotes are rating to a value or a quantity line at the midpoint
- Midpoint
EX: Midpoint of the interstates. Two lanes of the interstate
If you have an even number, you will average 2 data elements. Odd number won’t have to average.
Median
The value that appears the most often.
You can have more then 1 mode
EX: Bi-Modal – 2 numbers are present the same number of time
Tri-Modal – 3 numbers
Multi-Modal – 4 or more numbers
Mode
Is a characteristic that can have different values
Variable
Shows the values that a variable can take, and the number of observations associated with each variable
Frequency Distribution
Denotes a value or position in a group relative to other values organized in order of magnitude
Rank
Raw data that bundles it into 25%
1st Quartile: 1-25%
2nd Quartile:26-50%
3rd Quartile: 51-75%
4th Quartile: 76:100%
The higher your _______ percentage the better performance you are.
Only If its your patient satisfaction scores. All depends on the indicator
