Study Notes
Research Variables
- Independent Variable: Factor manipulated to observe its effect on the dependent variable.
- Dependent Variable: Outcome measured to assess the impact of the independent variable.
- Extraneous Variable: Uncontrolled variables that may affect the relationship between independent and dependent variables.
Case Studies
-
Housewife's Pechay Plants:
- Independent Variable: Type of soil (online seller, backyard compost, bamboo tree soil).
- Dependent Variable: Growth of pechay plants after one month.
- Extraneous Variable: Weather conditions, pests, or soil nutrients.
-
Jenny's Phone Charging Experiment:
- Independent Variable: Charger and cable combinations (various combinations of family members’ chargers and cables).
- Dependent Variable: Time taken to fully charge the phone.
- Extraneous Variable: Battery condition of the phone, temperature while charging, or charger quality.
-
Teacher’s Learning Delivery Modes Experiment:
- Independent Variable: Learning delivery modes (pure online, pure modular, combination).
- Dependent Variable: Turnaround time for submission of activities.
- Extraneous Variable: Students’ prior knowledge, motivation, or access to resources.
Quantitative Research
- Definition: Involves the collection and analysis of numerical data to identify patterns, relationships, or causal effects.
- Characteristics: Objective measurement, statistical analysis, replicability, and generalizability of results.
Strengths of Quantitative Research
- Offers precise measurements and quantifiable results.
- Enables the testing of hypotheses and theories.
- Facilitates the identification of patterns and trends.
Weaknesses of Quantitative Research
- May overlook contextual and qualitative factors.
- Limited scope in capturing the complexity of human behavior.
- Risk of oversimplification of issues.
Types of Quantitative Design
- Descriptive Design: Accurately captures the characteristics of a population or phenomenon. Example: A survey measuring student satisfaction.
- Correlational Design: Examines the relationship between two variables without manipulation. Example: Assessing the relationship between study habits and academic performance.
- Ex Post Facto Design: Investigates relationships by looking at data from events that have already occurred. Example: Analyzing the impact of past educational interventions on current performance.
- Quasi-Experimental Design: Explores the effects of an intervention without random assignment. Example: Comparing outcomes in two classrooms using different teaching methods.
- Experimental Design: Tests hypotheses by manipulating variables in controlled conditions. Example: A clinical trial testing a new medication's effectiveness.
Contributions of Quantitative Research to Fields
- Natural and Physical Science: Objective measurement of phenomena, leading to advancements in technology.
- Education: Improved learning methods through statistical evaluation of educational strategies.
- Sports: Analysis of performance data leading to enhanced training techniques.
- Arts and Design: Research into audience preferences shaping content creation.
- Agriculture and Fisheries: Studies support sustainable practices enhancing yield.
