APP 006 | PR2 Flashcards
All the members of a specific group being studied.
Population
A portion chosen from the population.
Sample
-The method of selecting samples from populations.
- The action or process of selecting the individuals who will participate in the study.
Sampling
Measures the number of individual samples measured in or observations used in a survey or experiment.
Sample Size
What are the two types of Sampling Techniques

What are the two types of Sampling Techniques
Probability
Non-probability
What are the probability sampling techniques
Simple random sampling
Systematic sampling
Cluster sampling
Stratified sampling
Selecting a sample randomly from a population
Simple Random Sampling
Selecting every nth person from a population.
Samples are selected in intervals.
Systematic Sampling
The population is divided into groups or cluster and then entire groups are randomly selected
Cluster Sampling
The population is divided into groups or cluster and then entire groups are randomly selected
Cluster Sampling
Divided into groups based on characteristics such as age, occupation or gender.
Stratified Sampling
What is the
SYSTEMATIC SAMPLING FORMULA | SLOVIN’S SAMPLING FORMULA
n = N/1+Ne²
What are the NON-PROBABILITY SAMPLING TECHNIQUES
Purposive Sampling
Snowball Sampling
Convenience Sampling
Voluntary Response Sampling
Qouta Sampling
Selecting specific individuals or items for a particular often due to their expertise or unique characteristics.
Purposive Sampling
Selecting specific individuals or items for a particular often due to their expertise or unique characteristics.
Purposive Sampling
Used when studying hard-to-reach or hidden populations. It starts with an initial participant who refers to others potential participants.
Snowball Sampling
Selecting individuals or items that are most accessible to the researcher.
Convenience Sampling
Researchers seeks volunteers to participate in studies.
-Participants offers insights willingly
Voluntary Response Sampling
Divides the population into sub-groups or quotas based on specific characteristics.
Qouta Sampling
Device being used to gather data
Research Instrument
The course of action (process of developing, testing, and using the device).
Instrumentation
What are the Measurement Scales?
Nominal
Ordinal
Interval
Ratio
Data that are categorically arrange.
Nominal
Data that are in ordered or ranked.
Ordinal
- Represent equal intervals in different segments on a continuum.
- Data has no zero.
Interval
- Equal distances from a known zero point.
- Data has real zero.
Ratio
refers to the ease with which an instrument can be administered, interpreted by
Usability
refers to the ease with which an instrument can be administered, interpreted by
Usability
the extent to which a concept is accurately measured in a quantitative study.
Validity
refers to the consistency of a measure.
Reliability
What are the two types of validity
Content Validity
Construct Validity
Criterion Validity
the instrument adequately covers all the content that it should with respect to the variable.
