Ceiling and Floor Effect
September 12, 2024
Ceiling and Floor Effect: Constraints in Data Measurement In research, particularly in experimental and survey-based studies, ceiling and floor effects refer to limitations in the data that prevent accurate measurement of variables. These effects occur when responses or scores cluster at the extreme high or low ends of the scale, limiting the ability to detect
Casual inference
September 12, 2024
Causal Inference: Understanding Cause-and-Effect Relationships Causal inference is a key concept in research that focuses on determining whether a cause-and-effect relationship exists between variables. In many scientific fields, especially in psychology, medicine, social sciences, and economics, understanding causality is crucial for drawing meaningful conclusions from research. While correlation shows a relationship between two variables, causal
Block Randomization
September 11, 2024
Block Randomization: Ensuring Balanced Study Groups In experimental research, ensuring balanced and unbiased group assignment is essential for maintaining the validity of the study’s results. Block randomization is a method used to achieve this balance, especially in clinical trials and other research that requires random assignment of participants. This technique helps control for variables and
Basic Research
September 9, 2024
Basic Research: Advancing Knowledge Through Inquiry Basic research, also known as pure research or fundamental research, plays a crucial role in expanding our understanding of the world by investigating fundamental questions and theories. Unlike applied research, which aims to solve specific real-world problems, basic research seeks to increase knowledge for its own sake, without a
Baseline stage
September 9, 2024
Baseline Stage: Establishing a Starting Point in Research In the context of research, the baseline stage is a critical initial phase that serves as the foundation for measuring changes or effects in a study. Before any interventions, treatments, or manipulations are applied, researchers gather baseline data to understand participants’ or subjects’ conditions at the start.
Attrition
September 8, 2024
Attrition: A Common Challenge in Research In research, particularly longitudinal studies and clinical trials, attrition is a term that refers to the loss of participants over time. Attrition can occur for various reasons, such as participants dropping out, losing interest, moving away, or experiencing adverse effects from treatments in experimental settings. High rates of attrition
Archival Records
September 8, 2024
Archival Records: A Key Resource in Research In the realm of research, particularly in social sciences, history, and psychology, archival records play a critical role in providing access to historical data and documents. These records are invaluable for understanding past events, trends, behaviors, and policies, allowing researchers to analyze data that has been collected and
Applied Research
September 6, 2024
Applied Research In the field of research, scholars often distinguish between two main types: basic research and applied research. While basic research is concerned with expanding theoretical knowledge, applied research focuses on solving practical, real-world problems. Applied research is highly relevant in fields such as psychology, education, health sciences, and business, where researchers aim to
ANOVA
September 6, 2024
ANOVA In the realm of research, particularly in psychology and social sciences, it is essential to understand how variables interact and how different groups compare. One of the most widely used statistical methods to achieve this is ANOVA, short for Analysis of Variance. This powerful tool helps researchers determine whether there are significant differences between
