Data Analysis and Statistical Modeling in R

via Udemy

Overview

Learn the foundation of Data Science, Analytics and Data interpretation using statistical tests with real world examples

What you'll learn:
  • Statistical modelling in R with real world examples and datasets
  • Develop and execute Hypothesis 1-tailed and 2-tailed tests in R
  • Test differences, durability and data limitations
  • Custom Data visualisations using R with limitations and interpretation
  • Applications of Statistical tests
  • Understand statistical Data Distributions and their functions in R
  • How to interpret different output values and make conclusions
  • To pick suitable statistical technique according to problem
  • To pick suitable visualisation technique according to problem
  • R packages which can improve statistical modelling

Before applying any data science model its always a good practice to understand the true nature of your data. In this Course we will cover fundamentals and applications of statistical modelling. We will use R Programming Language to run this analysis. We will start with Math, Data Distribution and statistical concepts then by using plots and charts we will interpret our data. We will use statistical modelling to prove our claims and use hypothesis testing to confidently make inferences.
