What does it mean for code to be minified?

• It’s typed in really small font like 6pt.

• It’s written only referencing functions contained in a library or API so that you only need to look at the function calls and not the definitions.

• All of the spaces are removed from the code so that it is unreadable.

When we inspect an element through developer tools, we are looking at:

• The page as it was intended to work.

• The state of the page before it was loaded.

• The current state of the page while it is being loaded.

• The current state of the page after it has been loaded.

Developer tools can help with

A. Testing and debugging a site or web app.

B. Diagnosing problems quickly on a site or web app.

C. Building and maintaining a more secure site or web app.

D. Modifying site or web app elements and sending the changes back to the server.

E. Changing code in real time to see how it impacts the site or web app on the fly.

There are multitudes of different kinds of charts that we commonly use to visualize data. In which of the following would a chart or visualization help to accomplish the accompanying task described?

• You want to track the number of times you say “hello” today.

• Your school wants to track how many people attend the football games over time throughout the school year.

• You are trying to figure out what happens when different colors are mixed.

• You need instructions on how to bake a cake.

Which of the following statements is NOT a benefit of using computers to process data?

• People can use computers to find patterns in data and make predictions.

• Computers help people visualize data so that it is easy to extract useful information.

• Websites can gather large amounts of personal data without the user knowing.

• Computers are able to easily process, manipulate, and display large amounts of data in a short amount of time.

Which of the following statements is an example of computer readable data?

• A handwritten note.

• Brain waves.

• A physical photograph.

• A digital spreadsheet.

A natural science museum opened a new display that lets the visitors view animations of a coral reef. The animations show how the health of the coral reef varies based on water temperature, pollution levels, and the number of fish living around the reef. The visitors are able to choose a numerical value for each of the conditions. The exhibit’s animations are determined by using a database to look up how healthy the coral reef is at the particular settings the visitor chooses and displaying a corresponding picture.

What is the biggest advantage of using an interactive exhibit like this instead of showing a poster with the same information?

• The interactive display will be easier to create.

• By allowing the visitors to interact with the exhibit, the visitors will be able to understand coral reefs better.

• The interactive display will be more visually appealing than a static poster.

• Scientists will be able to learn more about the coral reefs by tracking the visitors’ interactions.

Which of the following statements is true about data visualizations?

• Visualizing data has only been possible since computers have become widespread.

• Visualizations take many forms, from tables to charts to images.

• There is always one exact visualization that should be used to show a particular aspect of a dataset.

• The only way to extract information from data is by using a visualization.
