The Differences Between Nominal Data Scale and Ordinal Data Scale in Research Variable Measurement
In statistical analysis, data measurement scales are divided into four main categories namely nominal scale, ordinal scale, interval scale, and ratio scale. A proper understanding of the differences among these scales is crucial for determining the appropriate data analysis method.
Dummy Variables in Multiple Linear Regression Analysis with the OLS Method
Multiple linear regression analysis is a well-known technique frequently used by researchers to analyze the influence of independent variables on dependent variables. The ordinary least squares (OLS) method is one of the most commonly used methods in this analysis.
Can nominal scale data be analyzed using regression analysis?
Regression analysis is commonly used to examine the influence of independent variables on dependent variables observed in a study. However, regression analysis is more suitable for data with interval or ratio scales. How about data with nominal scales, can regression still be used?
How to use dummy variables as dependent variables in regression analysis
Researchers will generally choose the ordinary least square linear regression method if the variable measurement scale is an interval or ratio scale. If the measurement scale of the data is interval or ratio, it is easy to fulfill the possibility of passing the required assumption test.
