Sampling methods with Python

Sampling Methods in Python

Sampling is a fundamental process in research and statistics, allowing meaningful conclusions to be drawn from a representative subset of a larger population. In this article, we will review the concept of sampling and the main methods used to select representative samples. Through practical examples in Python code and theoretical considerations, we will illustrate the importance of careful sample selection and the applications of different sampling methods.

Longitudinal Data and study techniques with Python

Longitudinal data in statistics and study techniques with Python

Longitudinal data in statistics refers to observations collected on the same study unit (for example, an individual, a family, a company) repeatedly over time. In other words, instead of collecting data from different study units at one point in time, you follow the same units over time to analyze the variations and changes that occur within each unit. In this article we will discover what they are and which study techniques to apply using Python as an analysis tool.

Tidyverse and descriptive statistics

Tidyverse, an ideal tool for Descriptive Statistics with R

Descriptive statistics is a crucial step in data analysis, providing a detailed overview of the main characteristics of a dataset. R, with its vast ecosystem of packages, offers a powerful and coherent solution to address this phase. Among these, Tidyverse stands out, a set of packages designed to improve data manipulation, analysis and visualization in R.

Centrality Measurements of a distribution

Centrality Measurements of a Distribution with Python

Centrality measures, such as the mean, median, and mode, identify the typical value of a data set, providing a reference point for understanding the distribution. These measures work synergistically with measures of dispersion, such as standard deviation and IQR, to quantify the variability around the central value. Considering both of these aspects offers a comprehensive perspective of the distribution, essential for statistical modeling, informed decisions, and the accurate description of data.

Measurements of dispersion of a distribution

Measurements of Dispersion of a Distribution in Python

Calculating measures of dispersion, such as standard deviation and IQR, is crucial for evaluating the variability of data around its central tendency. These measures provide critical information about the distribution, allowing you to identify outliers, compare distributions, and make informed decisions. Understanding variability is essential for process control, building accurate statistical models, and supporting predictions and decisions in different contexts.
