Cohen’s f: A Measure of Effect Size in ANOVA In research, when comparing more than two groups, researchers often use Analysis of Variance (ANOVA) to test whether there are statistically significant differences among the groups. Cohen’s f is a measure of effect size used in ANOVA to determine the strength of the differences between multiple … Read more
Coding: A Key Process in Qualitative Data Analysis In the context of research, particularly qualitative research, coding refers to the systematic process of organizing and categorizing data into meaningful segments. It is a crucial step in data analysis, enabling researchers to identify patterns, themes, and insights from raw data, such as interviews, field notes, or … Read more
Central Tendency: The Heart of Data Distribution In research, particularly in statistics, the term central tendency refers to the concept of finding a central or typical value in a set of data. It provides a summary of a data set by identifying a single value that represents the middle point of a data distribution. This … Read more
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 … Read more
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 … Read more
Case Study: An In-Depth Examination of Complex Phenomena A case study is a qualitative research method that allows researchers to explore and understand complex phenomena in real-life contexts. It is widely used in fields like psychology, education, social sciences, and business to gain in-depth insights into a particular individual, group, or situation. This method provides … Read more
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 … Read more
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 … Read more
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. … Read more
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 … Read more
