Anаlyticаl Prоblem 2: Evаluating the "SafeWalk" App. Cоntext: "SafeWalk" is a mоbile app designed to help students walk home safely at night. It features a "Panic Button" and GPS tracking. You need to evaluate the usability and reliability of the Panic Button feature. 1. Requirements: Define one Functional Requirement for the Panic Button and one Non-Functional Requirement (specifically related to Performance/Latency) using the standard format (e.g., "The system shall..."). 2. Evaluation Plan (DECIDE): - Determine Goals: What is the primary goal regarding user safety? Choose Paradigm: You must choose between a Lab-based Usability Test or a Field Study. (a) Scenario A: You choose the Lab. Defend this choice based on Ethics and Safety. (b) Scenario B: You choose the Field. Defend this choice based on Context (e.g., lighting, noise, fear). 3. Data Analysis: You run a Within-Subjects test where users try the old button vs. the new button. The data for "Time to Activate" is heavily skewed (not a normal distribution). Why would a standard Mean (Average) be misleading here? Which measure of central tendency should you use instead? If you compare the two designs statistically, why is a Paired T-Test risky if the data is non-normal?
