____ data is an abstraction of _____ data.
○ analog, real - world
○ analog, digital
○ digital, analog
○ real - world, digital

Explanation:

• For the first question: Visual representations like graphs are designed to present data in a visual format. The key advantage is that they allow viewers to quickly identify patterns, trends, and relationships (connections) among data points. Spreadsheets (first option) are often more flexible for data entry and manipulation rather than for visual connection - seeing. Computers (third option) typically use raw data (not graph - formatted data) more easily. Summing numbers (fourth option) is a basic arithmetic operation that can be done in many ways, not a unique advantage of graphs.
• For the second question: Digital data is a discrete, binary - based (0s and 1s) representation. Analog data is a continuous representation. Digital data is created as an abstraction (a simplified, coded version) of analog (real - world, continuous) data. For example, an analog sound wave (continuous) is converted into digital audio data (a series of numbers representing the wave at discrete intervals).

Answer:

• First question: Graphs help us see connections visually.
• Second question: Digital, analog.
