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.
ICT: Data analytics drives innovation in technology and software development.
Social Science: Surveys and data analysis inform public policy and societal understanding.
Business and Accounting: Statistical methods enhance financial forecasting and management strategies.

Example Quantitative Studies

Education: "The Better You Feel the Better You Learn" demonstrates how colors and shapes influence learning outcomes.
Medicine: Studies on treatment effectiveness quantify health interventions.
Sports: Performance analytics improve athlete training and strategies.
Food Industry: Research on consumer preferences informs product development.
Agriculture: Analysis of crop yields guides farming practices.
Arts: Audience response studies enhance artistic endeavors.
Social Science: Surveys provide insights into social behaviors and trends.
Environmental Science: Quantitative studies evaluate ecological impacts.
ICT: Research in user interaction improves software usability.
Energy: Studies analyze consumption patterns for better resource management.
