D. DIAGRAMS


- Any line drawing that shows arrangement and relations as of parts to the whole, relative values, origins and development, chronological fluctuations, distributions, etc. –DALE

The word GRAPH is sometimes used as a synonym for diagram.

Types of a Diagram


•Affinity Diagram


- used to cluster complex apparently unrelated data into natural and meaningful groups.

- is a tool that gathers large amounts of language data (ideas, opinions, issues) and organizes them into groupings based on their natural relationships .


Tree Diagram


- Used to chart out, in increasing details, the various tasks that must be accomplished to complete a project or achieve a specific objective.


Fishbone Diagram


- Also called cause-and-effect diagram. It is a structured form of brainstorming that graphically shows the relationship of possible causes and sub causes directly related to an identified effect/problem. It is most commonly used to analyze work-related problems.


E. CHARTS


- diagrammatic representation of relationships within an organizations.

• Time Chart• Tree or Stream Chart• Flow Chart• Organizational Chart• Comparison and Contrast Chart• Pareto Chart• Run Chart or Trend Chart

Time Chart


- tabular time chart that presents data in ordinal sequence.



Tree or Stream Chart

-depicts development, growth and change by beginning with a simple course with spread outs into many branches.


Flowchart

- visual way of charting or showing a process from beginning to end. It is a means of analyzing a process. By outlining every step in a process, you can begin to find inefficiencies or problems.

Organizational Chart

- shows how one part of the organization relates to other parts of the organization.



Comparison and Contrast Chart



Pareto chart

- type of bar chart, prioritized in descending order of magnitude or importance from left to right.



F. GRAPHS

- pictures that help us understand amounts. These amounts are called data.


Circle Graph- is shaped like a circle.

It is divided into fractions that look like pieces of pie, so sometimes a circle graph is called a pie graph. Many times the fractional parts are different colors and a key explains the colors.



Bar Graph

- uses bars to show data. The bars can be vertical (up and down), or horizontal (across). The data can be in words or numbers.




A Picture Graph

- uses pictures or symbols to show data. One picture often stands for more than one vote so a key is necessary to understand the symbols.


Map- is a visual

representation of an area — a symbolic depiction highlighting relationships between elements of that space such as objects, regions, and themes.
