Simple linear regression (SLR) is often used in Data Science. Describe and explain what are the roles of simple linear regression in Data Science. Illustrate with a real‐world application for each of the role described. Briefly explain how they perform the roles.

Tips

Guideline: about 1000 words

First, give a brief description of Simple Linear Regression (SLR) Then explain the roles of SLR in Data Science
Find real‐world examples illustrating the roles of SLR that you described.

Credible sources: e.g. journal/conference articles, government reports…etc

Briefly explain the scenarios of the real‐world applications and the roles of SLR in the applications.
List your references under the heading ‘References’. Use Harvard style for referencing.

PART B


Prediction of Height from Metacarpal Bone Length

When anthropologists analyse human skeletal remains, an important piece of information is living stature. A method of predicting the height of an individual based on measurements of small bones in the skeletal remains is required. For a random sample of nine humans, the length of the metacarpal bone (mm) and the height (cm) were measured. Data as follow.
