kvintiileillä

Kvintiileillä, also known as quintiles, are a statistical method used to divide a population into five equal parts based on a specific variable, such as income or wealth. Each quintile represents 20% of the population and is ranked from the lowest to the highest based on the variable being studied. The first quintile, or Q1, includes the lowest 20% of the population, while the fifth quintile, or Q5, includes the highest 20%. This method is commonly used in economics, sociology, and demography to analyze income distribution, wealth disparity, and other social indicators. By dividing the population into quintiles, researchers can identify trends, inequalities, and disparities within different segments of the population. Kvintiileillä provides a clear and concise way to compare and understand the distribution of a variable across different segments of the population.
