This type of sampling is used in research where known variables in the population are critical for receiving representativeness
What is stratified random sampling?
Can be used to measure pain, fatigue, quality of life, and health status
What is a visual analog scale?
The highest level of measurement; allows researcher to conduct descriptive and inferential stats (age, weight, height, income)
What is ratio?
An instrument is said to have this when it measures what it is SUPPOSED to measure
What is validity?
Sampling method also known as multistage sampling; includes lists of states, cities, institutions, or organization with which elements of identified population can be linked
What is cluster sampling?
In this type of non-probability sampling, researcher enters available subjects into the study until desired sample size is achieved
What is convenience sampling?
Printed instrument used to gather numerical data
What is a questionnaire?
Example of this level of measurement includes Likert Scales; the second lowest level of measurement
This method of determines stability of an instrument by using the new instrument more than once under similar circumstances
What is test-retest?
Considered the most effective in obtaining a representative sample.
This type of nonprobability sampling is similar to stratified random sampling in the way that is selects samples from strata, yet differs due to the lack of randomization in selecting elements
What is quota sampling?
What is seven?
What is nominal?
This tests reliability using 2 observers to measure the same event
What is interrater reliability?
This type of sampling uses a formula in selecting elements in research
What is systematic random sampling?
This type of nonprobability sampling may include snowball sampling and network sampling
What is purposive sampling?
Quantitative data obtained by assigning numerical values to biological, chemical, and microbiological phenomena
What are physiological measures?
In this level of measurement, the distance between each value on the scale are equal and there is a meaningful value between the distances.
What is interval?
This type of reliability test determined the internal consistency of the instrument; is frequently used with dichotomous items
What is Kuder-Richardson coefficient?
This type of sampling ensures that all levels of identified variables are represented
stratified random sampling
This type of nonprobability sample is useful when the aim is theory and concept development
What is theoretical sampling?
Quantitative data that is often used in EBP and Quality Improvement Projects
What is an. electronic medical record (EMR)?
In this level of measurement, higher numbers mean higher value, but intervals are not equal
What is ordinal?
This type of test for instrument reliability is used with internal or ratio measurement
What is Cronbach's alpha?
