Introduction

This presentation summarizes the analysis of three important economic indicators across various countries: - Inflation Rate - GDP Growth Rate - Life Expectancy

The data comes from the World Development Indicators (WDI) dataset, published by the World Bank.

Exploratory Analysis

Inflation Rate Distribution

  • The histogram shows the distribution of inflation rates across different countries.
  • Most countries have low inflation rates, but a few outliers show exceptionally high rates.

Distribution of Inflation Rate

GDP Growth Rate Distribution

  • The histogram shows a more balanced distribution for GDP growth rates.
  • Most countries have moderate growth rates, while a few show rapid growth.

Distribution of GDP Growth Rate

Life Expectancy Distribution

  • The life expectancy histogram shows that most countries have life expectancies around 70-80 years.
  • This indicates improvements in healthcare globally.

Distribution of Life Expectancy

Indicator Relational Analysis

Life Expectancy vs GDP Growth Rate

  • Higher life expectancy is often linked to healthier workforces and stronger economies.
  • The scatter plot below visualizes the relationship between life expectancy and GDP growth rate.
