ASSESSMENT TASKS
Task 1 FORMATIVE TASK k-means Clustering in Principle
FORMATIVE TASK
Instruction: Produce a briefing document for your boss to explain k-means clustering and its potential uses in your organisation. The report must contain the following:
- An outline of what is understood by k-means clustering, and the steps involved in the k- means clustering
- Identify and explain how to determine the optimal number of clusters ‘k’ by using the elbow method, and how to interpret SSE and WSS.
- Discuss the potential uses of k-means clustering within your organisation, and how it might help promote the business of the
Task 2 SUMMATIVE TASK k-means Clustering in Practice
SUMMATIVE TASK
Instruction: Undertake a k-means clustering for your organisation and write a report on it. Your report must contain the following:
- An outline of how Python was used to create an accurate k-means algorithm, including an explanation of key terms such as Inertia and Silhouette Score. (LO 2.1, 3.1)
- Identify and explain how accurate visualisation of the clusters generated was carried out, and how the Inertia and Silhouette score were interpreted. (LO 2.2, 2.1, 3.2)
- A judgment as to the conclusions that can be drawn from the use of the algorithm, and the accuracy of these conclusions in making future decisions (LO 2.2, 3.3)
