19. Criteria Excellent (4) Good (3) Fair (2) Poor (1)
Collaboration and
Participation
All group members actively participate and
collaborate effectively throughout the
activity. Contributions are equitable, and
all members engage in discussions and
decision-making processes.
Most group members participate and
collaborate effectively, but one or
two members may be less engaged.
Contributions are mostly equitable,
and discussions are generally
productive.
Some group members participate,
but collaboration is limited.
Contributions may not be
equitable, and discussions may
lack depth.
Few group members participate,
and collaboration is minimal.
Contributions are unevenly
distributed, and discussions lack
substance.
Application of
Sampling Techniques
The group selects an appropriate sampling
technique for the given scenario,
considering various factors such as
research objectives, population
characteristics, and feasibility. The
rationale for the chosen technique is clear
and well-supported.
The group selects a sampling
technique that is mostly appropriate
for the scenario, but some factors
may not be fully considered. The
rationale for the chosen technique is
generally clear but may lack depth in
supporting details.
The group selects a sampling
technique, but it may not be the
most suitable for the scenario. The
rationale for the chosen technique
is somewhat unclear or lacks
sufficient support.
The group struggles to select an
appropriate sampling technique
for the scenario. The rationale for
the chosen technique is unclear or
entirely absent.
Clarity and Coherence
of Explanation
The group provides a clear and coherent
explanation of their chosen sampling
technique, articulating how it addresses
the challenges presented in the scenario.
The explanation demonstrates a deep
understanding of the technique and its
application.
The group's explanation of their
chosen sampling technique is
generally clear and coherent, though
there may be minor inconsistencies
or gaps in reasoning. The connection
between the technique and its
application to the scenario is evident.
The group's explanation of their
chosen sampling technique is
somewhat unclear or lacks
coherence. There are noticeable
gaps in reasoning or
inconsistencies in the explanation.
The connection to the scenario
may be vague.
The group's explanation of their
chosen sampling technique is
unclear and lacks coherence.
There are significant gaps in
reasoning, and the connection to
the scenario is unclear or
nonexistent.
Critical Thinking and
Comprehension
The group demonstrates exceptional
critical thinking skills and comprehension
of sampling techniques. They engage in
insightful discussions, offer thoughtful
reflections, and provide constructive
feedback to other groups.
The group demonstrates good critical
thinking skills and comprehension of
sampling techniques. They engage in
meaningful discussions, offer relevant
reflections, and provide constructive
feedback to other groups.
The group demonstrates some
critical thinking skills and
comprehension of sampling
techniques. Discussions may lack
depth at times, and reflections
may be somewhat superficial.
Feedback to other groups may be
The group demonstrates limited
critical thinking skills and
comprehension of sampling
techniques. Discussions are
superficial, and reflections lack
depth. Feedback to other groups is
minimal or nonexistent.

21. The aim of this research is to evaluate the academic performance of senior high school
students in a large city.The study will focus on gathering data on students' grades across
different subjects to analyze trends and identify potential factors influencing academic
success.
Population Size (N): Let's assume there are 10,000 senior high school students in the city.
Desired Margin of Error (e): The desired margin of error is 5%.
