Study Notes

Strengths and Weaknesses of Research

Lack of depth in exploring problems or concepts due to insufficient data.
Incomplete explanation of human experiences; quantitative data may not capture subjective experiences.
Non-numerical aspects, such as feelings and beliefs, are inadequately addressed.
Rigid research design limits flexibility and adaptability to new findings.
Response options may be limited, constraining participants' answers to predefined choices.
Potential for inaccurate responses from participants, affecting data reliability.
Large sample sizes enhance the complexity of data collection processes.

Characteristics of Quantitative Research

Objective Nature: Focuses solely on factual, measurable elements rather than emotional or cognitive aspects.
Reliable Data: Utilizes objective analysis of samples representing populations, increasing credibility for decision-making and policy formulation.
Replication: The ability to repeat studies to verify findings enhances validity and reduces the risk of incorrect conclusions.
Visual Result Presentation: Utilizes numerical data for effective presentation through graphs, charts, and tables, improving comprehension.

Control of Variables in Research

True experimental research allows control over independent variables, whereas in ex post facto studies, these variables have already occurred naturally, limiting manipulation.

Comparative Studies Examples

Examines the social and economic impacts of tourism development on indigenous versus non-indigenous communities.
Compares agricultural practices between organic and conventional farming methods.
Analyzes differences in traditional and modern teaching methods in Filipino elementary schools.
Investigates socioeconomic factors influencing child nutrition across the regions of Luzon, Visayas, and Mindanao.

Variables in Quantitative Research

Defined as changing qualities or characteristics, including age, gender, intelligence, and achievements.
Rooted in the concept of variation, signifying differing values across time and situations.
Main Types of Variables:
- Interval/Ratio: Data with equal distances between categories. Example: Age measured in years.
- Ordinal: Ranked categories with unequal distances. Example: Frequency of checking Bitcoin prices.
- Nominal (Categorical): Non-ranked categories. Example: Preferences for currency types.
- Dichotomous: Two-category responses. Example: Gender identification as male or female.
