COURSE TITLE: Statistics for Business II
NAME OF INSTRUCTOR: Dr Tetyana Khramova
CREDIT WEIGHT AND WEEKLY TIME DISTRIBUTION: credits 3 (hrs lect 3 - hrs sem 0 - hrs lab 1.5)
COURSE DESCRIPTION: Students will deepen their skills in data analysis and decision making under uncertainty using quantitative methods. Regression analysis, modeling, and time series forecasting are applied to real data and business examples. The course also provides a basic understanding of optimization modelling, simulation modeling, and data mining. Students will learn to interpret output from statistical spreadsheets.
