WORKSHEET 3 – Conceptual Phase of the Research Process
Read on the Conceptual Phase of the Research Process (Magnaye,
B. and E. Reantillo, 2020, pp. 41-57) or read online about Research
Variables and Definition of Terms in Research. Answer the following:
I. Formulate five (5) research problems and identify the
independent and dependent variables.
1. Do tomatoes grow fastest under fluorescent, incandescent, or
natural light?
2. What is the effect of diet and regular soda on blood sugar
levels?
3. How does phone use before bedtime affect sleep?
4. How well do different plant species tolerate salt water?
5. Will plants grow faster when using organic or inorganic
fertilizer?
INDEPENDENT VARIABLE
1. The type of light the tomato
plant is grown under.
2. The type of soda drank (diet or
regular).
3. The amount of phone use
before bed.
4. The amount of salt added to
the plants’ water.
5. The different fertilizer used for
the plant.
DEPENDENT VARIABLE
1. The rate of growth of the
tomato plant.
2. The blood sugar levels.
3. Number of hours of sleep.
4. Plant growth, Plant wilting,
Plant survival rate.
5. The plant’s rate of growth.

II. Cite variables (at least 3) then define them conceptually and
operationally.
1. “Reach”
Conceptual: Street distance covered when walking a
specific distance from a single location
in all possible directions.
(Peponis J, Bafna S, Zhang Z. The Connectivity of Streets:
Reach and Directional Distance. Environ Plann B. 2008; 35(5):
881–901.)
Operational: A continuous measure, in miles, of the
street distance covered when walking
one mile from the residents’ block in
all possible directions. Higher scores
indicate greater reach
2. “Connectivity”
Conceptual: The extent to which a street is connected
within its local or immediate
neighbourhood.
(Bafna S. Space Syntax: A brief introduction to its logic and
analytical techniques. Environ Behav. 2003; 35(1): 17–29.)
Operational: The mean number of streets connecting
with each street in the area within a ½
mile radius from survey participant’s
residential block. A continuous
measure, with higher scores indicating
greater connectivity.
3. “Integration”
Conceptual: The extent to which a street segment or
set of streets is more or less accessible
from all other parts of the city
(Bafna S. Space Syntax: A brief introduction to its logic and
analytical techniques. Environ Behav. 2003; 35(1): 17–29.)

Operational: The mean value of the integration
measure for all streets within a ½ mile
radius from survey participant’s
residential block. A continuous
measure with higher scores indicating
greater integration relative to other
streets in the city.
