Introduction

The socioeconomic condition of an area reflects the level of economic progress. Inflation, as one of the determinants of economic conditions, is measured through the Consumer Price Index (CPI). Changes in CPI from time to time show the rate of increase (inflation) or declaration (deflation) of the prices of goods and services needed daily by the household. The Consumer Price Index (CPI) is a crucial indicator of economic conditions, and its analysis is essential for policymakers to make informed decisions.

Background

This study aims to analyze the differences in inflation rates between Sibolga City and Pematangsiantar City using the Wilcoxon test. The Wilcoxon test is a non-parametric test that is suitable for analyzing ordinal data or data that is not normally distributed. The CPI data of Sibolga City and Pematangsiantar City for the period 2017-2021 was used in this study.

Methodology

The Wilcoxon test was chosen because CPI data is not always normally distributed, so parametric tests such as the T test cannot be applied. The Wilcoxon test is a non-parametric test that is suitable for analyzing ordinal data or data that is not normally distributed. The data used in this study was obtained from the official website of the Central Bureau of Statistics (BPS) of Indonesia.

Results

The results of this study showed that there was no significant difference between CPI Sibolga City and Pematangsiantar City during the 2017-2021 period. This indicates that the inflation rate in both cities tends to be the same.

Discussion

The results of this study indicate that the factors that influence inflation in both cities tend to be similar, such as the dynamics of demand and supply, as well as government economic policies. This suggests that the economic policies implemented by the government have a significant impact on the inflation rate in both cities.

Why Wilcoxon Test?

The Meaning of Research Results

The results of this study indicate that the inflation rate in Sibolga City and Pematangsiantar City tends to be the same during the 2017-2021 period. This can indicate that the factors that influence inflation in both cities tend to be similar, such as the dynamics of demand and supply, as well as government economic policies.

Implications and Suggestions

This study has several implications and suggestions:

First, the results of this study can be a reference for local governments in formulating the right economic policy to control inflation.
Second, this research can be the basis for conducting further research on the factors that influence inflation in both cities.
Third, further research needs to be done to analyze differences in inflation in both cities for a longer period and taking into account other factors such as income level, economic structure, and fiscal policy.

Conclusion

Wilcoxon test shows that there is no significant difference between CPI Sibolga City and Pematangsiantar City in the 2017-2021 period. This indicates that the inflation rate in both cities tends to be the same. Further research needs to be done to understand the factors that influence inflation in both cities and formulate effective policies to control inflation.
