measures Flashcards
What is an outcome?
– A measurable individual, family, or community state, behavior or perception that is measured along a continuum and is responsive to clinical interventions.
What is an outcome measure?
– A set of items that are used to create scores that are “intended to quantify a patient’s performance or health status based on standardized evaluation protocols or close ended questions
What is an independent variable
what is being changed or manipulated
What is a control?
there is no independent variable everything stays the same
What is a dependent variable?
what is being measured
What type of variable would be in an experimental group
the independent variable
Two of the same type of plants are placed in the same spot and given different amounts of water the growth is then tracked what is the independent variable
the water
Two of the same type of plants are placed in the same spot and given different amounts of water the growth is then tacked what are the controls
the type of plant, the amount of son etc.
Two of the same type of plants are placed in the same spot and given different amounts of water the growth is then tacked what is the dependent variable
the growth of the plant
What 3 things are needed for true experimental design?
- Random assignment
- 2 groups
- Experimental group
- Control group
- Manipulation - Cause &
Effect with the independent variable
What is the process for and experimental design?
- Randomly assign subjects
- Test subjects - observed or
pretested on a dependent measure - Experimental variable
(independent variable) for experimental group - Control group – no
independent variable - Retest all subjects
What is Quasi Experimental Design
Ethics of randomization
- No randomization
1. Control Group
2. Manipulation
- No randomization
Pre-Experimental Design is different from a true experiment because
Missing 2 of the 3 criteria for true
experiment
Pre-Experimental Design Outcomes describe
relationships (notcause/effect)
Pre-Experimental Commonly consists of:
Case study (X O) Pretest-posttest design (OX O)
Survey Designs Measure
characteristics of a population
Describe a population, explore relationships
Survey Designs benefits
- Can typically get a large sample
- Gather a lot of information quickly
- Online, email, regular email
What is Meta-Analysis
Meta-Analysis A statistical technique in which the results of 2+ studies are mathematically combined to improve the reliability of the results.
What is the criteria for choosing studies?
-Studies chosen for inclusion must be sufficiently similar
