AP CSP Impact of Computing Pt 2 (Computing Bias & Crowdsourcing)

The developers of a music-streaming application are updating the algorithm they use to recommend music to listeners. Which of the following strategies is LEAST likely to introduce bias into the application?

• Making recommendations based on listening data gathered from a random sample of users of the application

• Making recommendations based on the most frequently played songs on a local radio station

• Making recommendations based on the music tastes of the developers of the application

• Making recommendations based on a survey that is sent out to the 1,000 most active users of the application

A mobile game tracks players’ locations using GPS. The game offers special in-game items to players when they visit real-world points of interest. Which of the following best explains how bias could occur in the game?

• Points of interest may be more densely located in cities, favoring players in urban areas over players in rural areas.

• Some players may engage in trespassing, favoring players in urban areas over players in rural areas.

• Special items may not be useful to all players, favoring players in urban areas over players in rural areas.

• Weather conditions may be unpredictable, favoring players in urban areas over players in rural areas.

A software company is designing a mobile game system that should be able to recognize the faces of people who are playing the game and automatically load their profiles. Which of the following actions is most likely to reduce the possibility of bias in the system?

• Testing the system with members of the software company’s staff

• Testing the system with people of different ages, genders, and ethnicities

• Testing the system to make sure that the rules of the game are clearly explained

• Testing the system to make sure that players cannot create multiple profiles

Which of the following activities is most likely to be successful as a citizen science project?

• Collecting pictures of plants from around the world that can be analyzed to look for regional differences in plant growth.

• Designing and building a robot to help with tasks in a medical laboratory.

• Sorting scientific records and removing duplicate entries in a database with a large number of entries.

• Using a simulation to predict the impact of a construction project on local animal populations.

Which of the following applications is most likely to benefit from the use of crowdsourcing?

• An application that allows users to convert measurement units (e.g., inches to centimeters, ounces to liters)

• An application that allows users to purchase tickets for a local museum

• An application that allows users to compress the pictures on their devices to optimize storage space

• An application that allows users to view descriptions and photographs of local landmarks

A mobile application is used to display local traffic conditions. Which of the following features of the application best exemplifies the use of crowdsourcing?

• Users can save an address to be used at a later time.

• Users can turn on alerts to be notified about traffic accidents.

• Users can submit updates on local traffic conditions in real time.

• Users can use the application to avoid heavily congested areas.
