3rd Quarter Reviewer

In Grade 7 classes, the teachers teaching research methods are interested in knowing what study techniques their students are utilizing. Rather than assessing all students, the researchers randomly select 10 students from each of the sections to comprise their sample.

Question:

 What sampling method did the researchers use to select participants?

• Cluster Sampling

• Systematic Sampling

• Stratified Sampling

• Simple random sampling

In Grade 7 classes, the teachers teaching research methods are interested in knowing what study techniques their students are utilizing. Rather than assessing all students, the researchers randomly select 10 students from each of the sections to comprise their sample.

Question:

If the Grade 7 consists of 5 sections, each with 40 students, how many students are not part of the sample?

• 50

• 100

• 150

• 200

In Grade 7 classes, the teachers teaching research methods are interested in knowing what study techniques their students are utilizing. Rather than assessing all students, the researchers randomly select 10 students from each of the sections to comprise their sample.

Question:

Why did the teachers choose to use stratified random sampling instead of selecting students from only one section?

• To minimize effort in the sampling process.

• To only focus on students who volunteered.

• To maximize the number of students surveyed.

• To ensure every section is represented in the sample.

In Grade 7 classes, the teachers teaching research methods are interested in knowing what study techniques their students are utilizing. Rather than assessing all students, the researchers randomly select 10 students from each of the sections to comprise their sample.

Question:

How does the distribution of homework hours help Teacher Mia analyze the balance of workload across the class?

• Most students (60%) fall within the middle range (4-6 hours), indicating that the majority likely find the workload unmanageable.

• A minority spend more than 4 hours (20%), possibly indicating a lack of engagement or challenges with motivation.

• A smaller minority spend less than 6 hours (15%), potentially indicating inefficiency, perfectionism, or an excessive workload.

• The distribution shows a generally balanced workload, but there are outliers who may require additional support to align with the rest of the class.

The Grade 7 students are tasked to create a project-based learning activity that helps them understand how to balance their time better. They will design a personalized weekly study plan to optimize their homework time while balancing other responsibilities.

Question:

Which project title best describes the student's learning activity?

• "My Time, My Success: Building the Perfect Study Plan"

• "From Chaos to Control: Less Mastering Time Management"

• "The Productivity Project: Minimizing Study Efficiency"

• "Lacking Time Balance: The Path to Academic Success"
