Data Science I (BA 2nd-3rd grade)
“Information Procesing Theory I” in K.G.
Objective
In this class, we will learn the statistical analysis method necessary for data science and practice it by “R” which is the programming language for statistical analysis. Data science is the study of analyzing big data, modeling phenomena, and creating new services and management strategies. In this class, we will learn the fundamental study necessary for statistical analysis such as analytics, linear algebra mathematics, statistics (up to descriptive statistics of one variable), and aim to be able to calculate those by computer programming .
Goal
- You can explain the meaning of the fundamental function of analytics.
- You can calculate values using basic functions of analytics.
- You can explain the meaning of the basic operation of linear algebra.
- You can conduct basic calculation of linear algebra.
- You can explain the meaning of descriptive statistics of one variable.
- You can conduct descriptive statistics of one variable.
- You can write a program code of R using basic control structure of programming.
