How to Choose a 5% or 10% Margin of Error in Slovin’s Formula | Calculating the Minimum Sample Size

Research Methodology / By Kanda Data / September 9, 2024

In calculating the minimum sample size using Slovin’s formula, researchers can choose a 5% or 10% margin of error. What’s the difference, and how do you choose the right one? In survey research, when observing a population, we are often faced with the challenge of a large population size that needs to be observed.

How to Create a Likert Scale Score Category (Ordinal Scale)

Statistics / By Kanda Data / September 6, 2024

Creating Likert scale score categories is essential to answer one of the research objectives, particularly in descriptive statistical analysis. We can categorize non-parametric variables that use the Likert scale into high, medium, and low categories. This information will significantly enrich the research findings.
