Data Analysis Using R

Course Description:

Data is everywhere-in businesses, schools, hospitals and research centers. This course is created to help learners make sense of the data using R. Whether you are a student, researcher or professional looking to upgrade your skills, this training introduces you to practical, real-world data analysis techniques  you can apply immediately. We focus on hands-on learning, breaking down complex concepts into simple steps so that even complete beginners can follow along confidently.

Course Objectives:

By the end of this training, the learner should be able to:

• Use R and R Studio proficiently.
•  Import, clean, and manipulate datasets.
•  Perform exploratory data analysis (EDA).
• Apply statistical analysis techniques.
•  Create compelling data visualizations.
•  Develop machine learning models.
•  Generate automated reports and dashboards.
•  Work with real-world datasets.
