Description

Welcome to our fourth course "Learn Statistics & Biostatistics Data Analysis From Scratch". In this course, you will start from the very fundamentals of Data and slowly move forward to the analysis of the data using different statistical tools. In an era dominated by big data and machine learning, statistics is the cornerstone that allows us to make sense of the vast amounts of information we collect. It provides the methodologies for the collection, analysis, interpretation, and presentation of data. This course not only makes you literate in the language of data but also empowers you to make informed decisions in business, science, and technology.In this course, you will also learn the R-Programming to calculate different statistics on your data. R programming is one of the most sought-after skills in the fields of statistics, biostatistics and data analysis. With its extensive libraries and frameworks, R provides an unparalleled platform for analyzing and visualizing data, making it an indispensable tool for statisticians and data scientists. This course provides hands-on experience with R, ensuring you can apply statistical methods effectively in real-world scenarios.This course is divided into Eight ModulesWhat is Data? - Understand the basics of data, its types, and how it's collected and organized.Introduction to R Programming - Dive into R and R-studio, a powerful tool for statistical computing and graphics, essential for modern data analysis.Descriptive Statistics - Learn to summarize and describe the essential features of numerical data, crucial for initial data exploration. You will also learn how to build their visualization. Handling Categorical Data - Explore techniques for effectively managing and analyzing categorical variables.Probabilities - Gain insights into the concepts of probability, a foundational pillar for statistical inference. You will understand the subjective, classical, conditional, etc probabilities concepts at the end of this module. Correlation - Discover the methods to measure the strength and direction of a relationship between two variables. We will explain to you the Pearson, Kendall and Spearman correlations.Regression - Understand how to model relationships between variables and make predictions. We will teach you about Simple linear Regression, Multiple Linear Regression, and Logistic Regression. Hypothesis Testing - Develop the ability to test assumptions and make decisions based on data. You will learn the Z-test, T-test and its types, F-test, ANOVA and its types, and Chi-Sq test and its types. This course is a unique blend of theory and practical. You will learn the theory of statistical concepts and along with it you will learn the R-programming to apply those statistical concepts to your data.  We hope this journey will be enlightening for you. After having this course, you will be confident to analyze your data by your own.
