3. Data Sources & acquisition
Data can be defined as the
quantitative or qualitative values
of a variable. Data is plural of
datum which literally means to
give or something given. Data is

7. Quantitative data are anything that can be
expressed as a number, or quantified. Examples of
quantitative data are scores on achievement tests,
the number of hours of study, or weight of a
subject. These data may be represented by ordinal,
interval or ratio scales and lend themselves to
most statistical manipulation.
Qualitative data cannot be expressed as a number.
Data that represent nominal scales such as gender,
social economic status, religious preference are
usually considered to be qualitative data.

8. Graphical Representation

10. Bar Chart

11. Histograms

12. Circle
Graphs or
Pie Charts

13. Table Chart
A table is a systematic arrangement of data
into vertical columns and horizontal rows.
The process of arranging data into rows and
columns is called tabulation

14. Essentials
of a Table
1. Title of the table
2. Captione
3. Box head
4. Stub head
5. Body of the table
6. Prefatory notes or head notes
7. Footnote:
8. Source not

15. Line Chart

16. Data
Mapping
Data mapping is the process
of mapping data fields from a
source file to their related
target fields. The accessibility
to required data can make
some organization more
successful. Somehow, data is
easier to use when it can be
visualized as well.
