Module 1 Lesson 2 Flashcards
refers to the process by which subjects, objects, and
practices are transformed into digital data.
‘Datafication’
Collected from an original
source of data
Primary DATA
data: Data collected from
interviews and surveys
Small data
Data collected from
transactions
Big data
Collected from published or
unpublished source of data
Secondary DATA
METHODS OF COLLECTION
INTERVIEW Method
QUESTIONNAIRE Method
REGISTRATION Method
OBSERVATION Method
EXPERIMENTAL Method
this is a direct way or personal contact with
the primary source of data
INTERVIEW Method
series of well - planned questions are asked to
the person (subject of the study)
INTERVIEW Method
this is an indirect way of collecting data that
may done online or through paper distributed
to the respondents of the study
QUESTIONNAIRE Method
this entails creating valid and reliable
questions, and selecting an appropriate
method for administration
QUESTIONNAIRE Method
gathering is done from concerned offices
REGISTRATION Method
data gathering is done purely based on the use of senses
OBSERVATION Method
gathering is done thru experimentation
EXPERIMENTAL Method
looking into the cause and effect relationships
of a certain parameter or event under a
controlled condition, which is commonly used
in the field of science
EXPERIMENTAL Method
6Vs of Big data
Volume
Velocity
Veracity
Value
Variety
Validity
The action or process of taking samples of something for analysis.
Data Sampling
Inherent
trait that researchers follow whenever they want to investigate or look into a
‘gap’
Data Sampling
Sampling Techniques
SIMPLE RANDOM SAMPLING
SYSTEMATIC RANDOM SAMPLING - stratified random sampling; cluster sampling
PURPOSIVE SAMPLING
QUOTA SAMPLING
CONVENIENCE SAMPLING
equal chances of being chosen to
be included in the study
SIMPLE RANDOM SAMPLING
population is divided in different classes and
each class must be represented in the study
Stratified Random sampling
in this techniques samples are selected not by individuals
but by groups or cluster.
Cluster Sampling
The samples were chosen with the sole purpose that they are knowledgeable
or suited to answer inquiries of the study
Purposive Sampling
This is commonly used in polls. The research sets a required number of
samples (quota) then, after meeting it the collection of data is done.
QUOTA SAMPLING
The samples were chosen based on the accessibility of the researcher to
the target participants in the study.
CONVENIENCE SAMPLING
