Description

Consulting is an integral part of an applied statistician’ s life, whether working in academia, government or industry. Statistical and methodological consultation may involve brief interactions to respond to very specific technical questions of a single client, or long term associations as a member of research projects. It always involves a form of ‘ reverse reasoning’, that is, figuring out the conclusion you want to come to, and finding a way to get there. Specifically, the consultant’ s problem is: What statistical procedure(s) could provide an appropriate answer to the client’ s research question, within all practical constraints? During the course, every two students will carry out a statistical consultation project with an actual client.

Course objectives

After this course the student is able to:
1. identify and recognize issues in a client project relevant for a statistical consultant, such as: research question, study design, sampling procedure, and measurement instruments;
2. choose and apply (an) appropriate analysis technique(s) to answer the client's research question(s);
3. effectively communicate the choice of analysis technique, the statistical assumptions, the analysis results and how these answer the research question to the client (both orally and in writing)

For more information, watch the video or go the the 'help-page' in MyTimetable. Please note: Joint Degree students Leiden/Delft have to merge their two different timetables into one. This video explains how to do this.

Mode of instruction

A combination of lectures and practicals. The lectures support the performance of the client project and the writing of the final report. The final report follows the lines of a substantive article (i.e., a paper written from the perspective of the client). The practicals consist of client meetings (i.e., meetings in which you talk to your client, observed by other students). For the client meetings, the students will be divided into smaller groups. The program and a syllabus are available on Brightspace and details will be announced on the first lecture day. An overview of the client projects for which the students can indicate their preference will be available a few days before the first lecture day on Brightspace. The students need to send their preference before the first lecture.

Assessment method

Final written report including reflection report (70%); final oral presentation (20%); active participation during the meetings (10%). Attendance to the lectures and client meetings is obligatory during the whole course. The weighted average of the grades of the written report, presentation and participation determines your final grade. Additionally, the grade on each of the three assessment criteria of the written report should be at least a 5.5 to pass this course. When a revision is needed of the final written report, the maximum grade for the revised report will be a 6.5.

Reading list

Various articles and book chapters on a) how to perform statistical consulting; b) how to handle missing data, and initial data analysis; c) how to report statistical methods and results to non-statistical readers, and d) ethical issues. Links to the articles will be provided on Brightspace.
