Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

Pre 1.1 Introduction

Course subject(s) Pre-knowledge Mathematics

This unit allows you to review some concepts from statistics that will be used throughout the course. You may want to review this before the start of Module 1 of the EdX course “Observation Theory: Estimating the unknown”, but it is also designed as a convenient source of reference to be used throughout the course.

The topics are:

  1. Deterministic and random variables
  2. Histograms and probability density functions
  3. Mean and variance
  4. Normal distribution

You are expected to be familiar with these topics before Module 1.2 on Quality and Types of Errors.
