Tutorial on Tabulating Likert Scale Data for Social Research
In social research, many researchers measure variables using the Likert scale. Have you ever conducted research involving variables measured with the Likert scale? In this article, Kanda Data will discuss variables measured using the Likert scale and provide a tutorial on how to tabulate Likert scale variables.
Tutorial on One-Way ANOVA Test for Non-Laboratory Research
The one-way ANOVA test is a parametric statistical test used to examine the differences in means across more than two sample groups. It is important to emphasize that the one-way ANOVA is only applicable when comparing three or more groups. If you are comparing the means of only two groups, then a t-test should be used instead.
Alternative to One-Way ANOVA When Data Are Not Normally Distributed
If you’re conducting research to compare the means of more than two sample groups, one-way ANOVA is a commonly used statistical test. However, using this test comes with certain assumptions that must be met, specifically, that the data are normally distributed and homogenous.
Assumption Tests in Linear Regression Using Survey Data
The most commonly used linear regression analysis by researchers is the Ordinary Least Squares (OLS) method. However, when applying linear regression with the OLS method, several assumptions must be met to ensure that the estimation results are consistent and unbiased.
What Is a Residual Value in Statistics?
If you’re working with data analysis using linear regression, especially the Ordinary Least Squares (OLS) method, it’s important to understand what a residual is. Why does this matter? Because several assumption tests in OLS regression rely heavily on residual values. That’s why you need a solid understanding of what residuals are and how to calculate them.
Normality Test in Regression: Should We Test the Raw Data or the Residuals?
When we choose to analyze data using linear regression with the OLS method, there are several assumptions that must be met. These assumptions are essential to ensure that the estimation results are consistent and unbiased. This is what we refer to as the Best Linear Unbiased Estimator (BLUE).
How to Find the T-Table Value for Regression Using Excel
In linear regression analysis, we often want to determine whether the independent variable truly influences the dependent variable. Therefore, linear regression analysis is one type of associative test that aims to determine how the independent variable affects the dependent variable.
How to Automatically Display Residual Values in Regression Analysis Using Excel
Residual values play an important role in linear regression analysis. These residuals are used for OLS assumption tests, such as normality tests and heteroskedasticity tests. For instance, one of the key assumptions in linear regression analysis is that the residuals are normally distributed.
