Topic outline

  • Course Overview

    This module discusses different aspects of variability.

    It discusses topics from probability theory and statistics that are relevant to WFM.

    Without going into mathematical details, you learn how to quantify variability, basic statistical concepts and how to avoid certain pitfalls.

    Topics in this course are: histograms, mean, median, standard deviation, significance, some well-known distribution and the relation between scale and randomness.

    • Introduction

      Please watch the video and answer the question afterwards.

    • Previous Knowledge

      Restricted Not available unless: The activity Introduction Exercise is marked complete
      In this part of the module you can test yourself to see if you have the required knowledge to do the module.

      Required knowledge for this module is some basic Excel experience. 

      Please download the Excel file and answer the questions. 

    • Histograms

      Restricted Not available unless: You achieve a required score in Previous Knowledge Quiz

      The first step in analyzing data is having a look at it by making a graph. In this topic you learn to make histograms for numerical data. 

      Please have a look at the first Excel demo, make a histogram using the first data set, look at the second demo, and use the second data set to make again a histogram. Then submit screenshots of both histograms.

    • Mean, Median and Standard Deviation

      Restricted Not available unless: The activity Submit histograms is marked complete

      In this topic you learn about the mean, median and standard deviation, and how to compute it in Excel.

      Please look at the clip, download the Excel file and answer the questions in the quiz.

    • Statistical Significance

      Restricted Not available unless: You achieve a required score in Mean, Median and Standard Deviation Quiz

      One or two exceptional outcomes can always occur. 

      In this topic we learn why we need large datasets to draw sound statistical conclusions.

      Please look at the two clips and make the exercises.

    • The Normal Distribution

      Restricted Not available unless:
      • The activity Statistical Significance Exercise 1 is marked complete
      • The activity Statistical Significance Exercise 2 is marked complete

      In this topic you learn about the basic properties of the normal distribution. 

      Please do the quiz after watching the clip.

    • The Lognormal Distribution

      Restricted Not available unless: You achieve a required score in Normal Distribution Quiz

      Please watch the clip and answer the question in the quiz.

    • The Poisson Distribution

      Restricted Not available unless: You achieve a required score in Lognormal Distribution Quiz

      Please watch the clip and do the quiz.

    • Scale

      Restricted Not available unless: You achieve a required score in Poisson Distribution Quiz

      Please watch the clip and then move on to the final assignment. Note that this topic is not mandatory for students enrolled in Forecasting Training. 

    • Final Assignment

      Restricted Not available unless: You achieve a required score in Poisson Distribution Quiz
    • Feedback and Certificate

      Before you move on to the next course, we would like to hear your feedback on this one.
