Types of Variables
1. Continuous Variables-can take infinite number on the value and categorized as:
Interval Variables- Difference between two values are significant:
Temperature in degree Celsius
Ratio Variables – Absolute zero :height, weight, and distance
2. Discrete Variables-categorical or classificatory variables with distinct value as:
Nominal Variables – Attributes are only named: eye color, business type
Ordinal Variables – Attributes can be ordered : grade level; military title
Kinds of Variables
1. Independent Variable - those that cause, influence or affect outcomes.
2. Dependent Variable – effects or outcomes of the influence of the independent
variables
3. Intervening or Mediating – those are in-between the independent and
dependent variables.
4. Control – measured in a study because they are potentially influenced the
dependent variable, using statistical procedures
5. Confounding – those that are not actually measures but they exist.

Concept Notes:
Designing research involves two separate sets of activities. First, the
conceptual design which determines everything you wish to achieve through the
research. Second, the technical research design which concerns how to realize all
this during the implementation stage of the study.
However, even in your own daily life situation, you can apply the systematic
way to solve your problem. Though it is somewhat personal; but still you can apply
the sets of activities to come up with best solution.
Exercises: In designing a research related to your daily life, choose a particular
event that you have experienced which made you stop and reflect. It may be
something that confused you or simply something that made you wonder. To let
you apply the concepts, do the activity using the Problem Solver Organizer

Concept Notes:
What is a research topic? A topic or problem is a general question which a
researcher needs to undertake. In selecting the topic, criteria such as technical
and personal can help you. Sources such as prevailing theories or philosophy,
observations, fields of interest, existing problem and needs of the community are
the best relevant sources of research topic.
Comparing Broad Topic and Specific Topic:
Example of broad topics: Blended learning in English Classes; Presidential
Election Results; Social Networking
Example of specific topics:
A correlation study on the use of blended learning in freshman English
classes and student achievement
The cause-effect relationships of social networking and online selling
Effects of vegetarian on Physical Health
However, a research topic must be specific, measurable, attainable, and
time-bounded. There are guidelines in selecting and narrowing down broad topic to
a manageable or specific topic, to wit:
1. Examine the literature
2. Talk over ideas with others
3. Apply to a specific
4. Define the aim or desired outcome of the study

The happiest days of your life?
James Field
School days should be a happy time in a young person’s life. What can make
people’s lives a misery during this time, then? In my opinion, there is one word
which answers this question- bullying. Unfortunately bullying is quite common in
schools where I live. It can affect the students at any age, and both boys and
girls. A friend of mine had a very negative experience at school last year as an
older boy continually called him names and sometimes used to post nasty messages
on Facebook. Obviously, my friend felt very upset, and it affected his self-
confidence. Some days he didn’t want to come to school at all. Bullying can be a
nightmare but there are things we can do to prevent it. Hopefully, one day all
students will be able to go to school without fear being bullied.

An important part in writing research in an academic discipline is to give
definition of key terms.
Operational definition must be considered in defining terms in the study.
This means that the variables and terms being used in the study must be
operationally defined. Thus, the universal meaning of the terms can be
understood by many people.
Two Types of Operational Definition:
1. Experimental Operational Definitions - manipulative
2. Measured Operational Definition-measurable and observable
However, there are terms or variables being used in the study which can be
defined based on the concept or principle.

Exercises: Tell whether the following definition of terms are operationally
defined or based on the concept or principle. Write OD (Operationally Defined)
and CB (Concept-Based definition). Write your answer on the space provided.

1. Quantitative research gathers data in a numerical form which can be put into
categories, or in rank order, or measured in units of measurement. This type of
data can be used to construct graphs and tables of raw data.
2. Statistics help to summarise our data, describing patterns, relationships, and
connections.
3. Tabulation is summarizing raw data and displaying it in compact form for
further analysis such as in table form.
4. Diagrams are charts and graphs used to present data. Examples: Bar graph,
Column chart, Pie chart, and other charts applicable for quantitative data

What is Conclusion? The conclusion is intended to help the reader understand
why your research should matter to them after they have finished reading the
paper. A conclusion is not merely a summary of the main topics covered but a
synthesis of key points.
Drawing Conclusions from Quantitative Research:
1. The approaches to drawing conclusions should provide the new knowledge and
insights needed to help solve the problem.
2. The conclusions should be derived from and consistent with the data analysis
methods.
3. Conclusions should focus on the answers to major problems raised in the study
more particularly on the results of hypothesis testing.
Exercises 1: A sample research article will be provided by your teacher and use
it to answer the checklist below:
What makes for good conclusions? YES NO
1. Did the researcher(s) summarize the results and use them to
support the findings?
2. Did the researcher (s) stick with a basic synthesis of information?
3. Did the conclusions state that the researcher(s) proved or
disproved the hypothesis?
4. If appropriate, did the researcher(s) state the relationship/
differences between the independent and dependent variable?
5. If appropriate, did the researcher (s) make a call to action?
6. Does the tone of the research paper; especially the conclusion,
consistent the entire way through?

What is Recommendation? Recommendations are linked to the main findings. They
are important in order to point the areas where actions can be taken to address
the challenges highlighted by the findings.
How do we do it? For recommendations to be useful they should be:
1. Specific - it must be clear exactly what is being recommended.
2. Measurable - it should be possible to tell whether the recommendation has been
implemented or not.
3. Accountable - the person or entity responsible for implementing the
recommendation should be identified.
4. Realistic - recommendations need to fall within the range of the possible.
5. Time-bound - the timetable for implementing the recommendation should also
be given
6. Coherent - should neither contradict nor seem to contradict each other.
7. Ordered by priority - which recommendations are of primary concern and which
ones are secondary.
8. Limited in number – not a “cloud” of recommendations and not demanding
9.Economic - the recommended actions should clearly deliver benefits in
proportion to their costs.
Exercises: With your present research study, formulate 2-3 recommendations
based on the objectives or problems, findings and conclusions.
