Learning Outcomes:

At the end of the course, students should be able to:

  • Summarize data sets using Descriptive statistics
  • Analyze the relationship between two variables
  • Analyze trend and seasonality in a time series data
  • Draw conclusion about a population using testing of hypothesis
  • Apply statistics to different managerial situations
