    コース概要
What statistics can offer to Decision Makers
- Descriptive Statistics- Basic statistics - which of the statistics (e.g. median, average, percentiles etc...) are more relevant to different distributions
- Graphs - significance of getting it right (e.g. how the way the graph is created reflects the decision)
- Variable types - what variables are easier to deal with
- Ceteris paribus, things are always in motion
- Third variable problem - how to find the real influencer
 
- Inferential Statistics- Probability value - what is the meaning of P-value
- Repeated experiment - how to interpret repeated experiment results
- Data collection - you can minimize bias, but not get rid of it
- Understanding confidence level
 
Statistical Thinking
- Decision making with limited information- how to check how much information is enough
- prioritizing goals based on probability and potential return (benefit/cost ratio ration, decision trees)
 
- How errors add up- Butterfly effect
- Black swans
- What is Schrödinger's cat and what is Newton's Apple in business
 
- Cassandra Problem - how to measure a forecast if the course of action has changed- Google Flu trends - how it went wrong
- How decisions make forecast outdated
 
- Forecasting - methods and practicality- ARIMA
- Why naive forecasts are usually more responsive
- How far a forecast should look into the past?
- Why more data can mean worse forecast?
 
Statistical Methods useful for Decision Makers
- Describing Bivariate Data- Univariate data and bivariate data
 
- Probability- why things differ each time we measure them?
 
- Normal Distributions and normally distributed errors
- Estimation- Independent sources of information and degrees of freedom
 
- Logic of Hypothesis Testing- What can be proven, and why it is always the opposite what we want (Falsification)
- Interpreting the results of Hypothesis Testing
- Testing Means
 
- Power- How to determine a good (and cheap) sample size
- False positive and false negative and why it is always a trade-off
 
要求
Good maths skills are required. Exposure to basic statistics (i.e. working with people who do the statistical analysis) is required.
