Business Statistics

Contents at WU (undergraduate level)

Descriptive Statistics

Hypothesis Testing (including Permutation Test) Regression, ANOVA (uni- and multi-variate) Model Selection

Time Series Analysis, Stochastic Processes

Problems

Only one lecture, 2 hours, just 4 ECTS points!

R Examination Package

A quick glance at the package

Packageexamson CRAN (free, open-source). Automatic exam generation.

Integrated facilities for correction.

Minimization of of time from design of exam to execution, correction, and publishing results.

Implementation at WU

Individual exams for each and every student.

Results are published online (web interface) within 4-24 hours after the exam.

Dos and Don’ts / Business Statistics

Main rule

Do not invent real world examples if you do not have a clue about the area and do not mix (and mess) application areas.

Example from current WU lecture

Hypothesis test, proportion test (second lecture) examples created by a mathematician: cheque reader and credit card.

Why Statistical Computing?

Tim Burners-Lee

“Journalists need to be data-savvy”

New world statistics

data-driven

computationally expensive visualization and immersion (online) data harvesting

(10)

Why R?

Advantages of R

Free Software State of the art low cost

no license hassle rather low level very transparent

Partial Immersion

Learning statistics is like learning a language

Language learning

steep learning curve mixes theory & application exposure maximizes results

Statistics learning

mediated with GUIs interactive usage of R early start with R exposure

Solution: Partial immersion

is a technique in which students are early on and repeatedly exposed to a new language. Content is provided in both the old and the new language.
