(M) Variable Identification and Definition Flashcards
- It is important that the data used in the study are operationalized in measurable terms
VARIABLE IDENTIFICATION
- Data are capable of taking on different values
- Usually easy to define and label or measurement is objective
VARIABLE
TOF. Variables can either be qualitative or quantitative
T
Types
- Gender
- Height
- Birth
- Place of Residence
- Weight
A. Qualitative
B. Quantitative
ABBAB
Types
- One whose categories can be measured and ordered according to quantity or amount or whose values can be expressed numerically
- One whose categories are simply used as labels to distinguish one group from another
- Discrete, Continuous
A. Quali
B. Quanti
BAB
QUANTITATIVE VARIABLE
- If it can assume only integral values or whole numbers.
- If it can attain any value including fraction or decimals
A. Continuous
B. Nominal
C. Ordinal
D. Discrete
E. Interval
DA
QUANTITATIVE VARIABLE
- Male or Female
- 1st, 2nd, 3rd
- -4C or -8C
- Height in cm
- Weight in kg
A. Interval
B. Nominal
C. Ordinal
D. Ratio
E. Discrete
SCALE OF MEASUREMENT:
BCADD
QUANTITATIVE VARIABLE
- Ranked or Ordered
- Label or Categories
- The exact distance between two categories can be determined but the zero point is arbitrary
- Zero point is fixed, no value below zero
A. Interval
B. Nominal
C. Ordinal
D. Ratio
E. Discrete
CBAD
CONCEPTS
TOF.
1. Are physical realities or absences of perception
2. Meaning may vary from the individual to individual
3. Unlike a variable, a concept cannot be measured objectively
4. It is therefore important for a concept to be converted into a VARIABLE
- F (mental image)
- T

Concepts
Fill in the blanks
- One must be able to formulate _____________ to be able to measure the concept and transform it to a variable
- Setting a/an _____________ to define
a concept is operationalizing the concept.
- criteria
- indicators or set of criteria
Study the examples
Example of operationalization of a concept “Burnout”
A specific way in which a variable or concept is measured in a study to ensure clarity and consistency.
operational definition
VARIABLES (RELATIONSHIP/ASSOCIATION STUDIES)
- Affects the dependent variables, cause, exposure factor, risk factor
- Affected by the independent variable, effect, outcome
- Extraneous (not the main focus of the study) or control variable
A. Independent
B. Dependent
C. Confounder
ABC
diagrammatic representation of
the hypothesis of relationship between independent and dependent variables.
