Using and Managing Data and Information Analysis Assignment - BA3020QA

This assignment comprehensively addresses data and information management, encompassing various analytical techniques. Task 1 focuses on a supermarket survey, including data categorization, frequency tables, and graphical representations of customer demographics and self-checkout usage. Task 2 involves constructing and interpreting a network diagram to represent project timelines. Task 3 requires the creation of a line graph and calculation of a moving average to analyze sales figures over several years. Task 4 delves into decision-making using a decision tree to analyze potential outcomes. Finally, Task 5 utilizes linear programming to optimize cheese production based on resource constraints and profit maximization. The assignment demonstrates a strong understanding of data analysis, visualization, and decision-making methodologies.

TASK 2
Network diagram- A network diagram is an illustration of a project that consists of a set of linked
arrow and frames that define the interdependence of the project tasks (Pearlson, Saunders, and
Galletta, 2019). Packages or arrows display activity descriptions, and arrows indicate the
association between the operations.
