A research design that uses numerical data and statistical analysis to answer research questions.

A type of quantitative research where researchers manipulate one variable (independent) to observe its effect on another (dependent).

The variable that is manipulated in an experiment.

The variable that is measured to see the effect of the independent variable.

The overall plan or strategy for conducting a research study.

To establish clear objectives for a study, explaining its intention to test or analyze certain aspects of the problem statement.

The step-by-step approach in collecting data during the study, including the manner and methods for data collection.

The extent to which a research design effectively addresses research aims, supports appropriate conclusions, and involves scientific rigor.

Experimental research needs a treatment, controlling external factors, and random participant assignment.

A research design that manipulates an independent variable but lacks random participant assignment.

Examines the relationship between two variables, but doesn't prove cause and effect.

As one variable increases, the other increases too.

As one variable increases, the other decreases.

A connection where one thing causes another to happen.

Assigning participants to groups randomly to ensure fair comparison.

A research design aimed at describing a specific characteristic or behavior within a population. It focuses on observing and documenting patterns in naturally occurring phenomena.

Descriptive research cannot establish cause-and-effect relationships, as it only observes existing patterns. It can't explain why these patterns exist.

A type of descriptive research that gathers data from a large sample of people through questionnaires or interviews to understand trends and opinions.

A type of descriptive research that analyzes population characteristics like age, gender, income, and education to understand demographic patterns.

A type of descriptive research that studies the distribution and patterns of diseases and health conditions within a population.

Examining the findings of a descriptive study to identify patterns, trends, and key characteristics of the population being studied.

Investigating the relationship between various parenting styles and the self-esteem levels of Filipino adolescents.

Exploring the career aspirations of senior high school students, identifying their preferences based on their academic track.

A quasi-experimental design lacks random assignment of participants to groups, meaning the groups might not be truly comparable before the treatment is applied. The lack of randomization weakens the ability to establish a causal relationship between the independent and dependent variables.

Controlling extraneous variables ensures that any observed changes in the dependent variable are due specifically to the manipulation of the independent variable, not other factors. This allows for isolating the true effect of the treatment.

Correlational research explores the relationship between two or more variables. It examines whether the variables change together (co-vary) but doesn't establish if one variable causes the other.

Descriptive research aims to describe characteristics or patterns within a population. Common types include survey research, which investigates opinions or behaviors, demographic research, which examines population characteristics, and epidemiological research, focusing on disease patterns and health trends in a population.
