Computational Thinking
Breaking a large, complicated problem into smaller, more manageable parts is called what?
Decomposition
A simplified representation of a real-world system or object used to understand or study it is called what?
Model
Facts, measurements, observations, or other pieces of information collected for analysis are called what?
Data
The process of examining data to discover useful information, patterns, and insights is called what?
Data analytics
Information organized into rows and columns is called what?
Table
You notice that every time you study late at night, you make more mistakes on your homework. Identifying this repeated relationship is an example of what?
Pattern recognition
A computer program predicts what might happen during a hurricane without actually creating a hurricane. What is this an example of?
Simulation
A smartwatch collects your heart rate and sends the information to your phone over the internet. What concept does this demonstrate?
Internet of Things (IoT)
A company looks at last year's sales and determines that it sold 50,000 products. What type of analytics is this?
Descriptive analytics
You want to compare the number of students in five different majors. Which visualization would be a good choice?
Bar chart
A map doesn't show every tree, building, and person in a city. Instead, it only shows the information needed to navigate. What concept does this demonstrate?
Abstraction
A model is useful because it represents reality without including every single detail. What concept explains why unnecessary details can be left out?
Abstraction
A company has millions of customer records stored in its computer systems. What term describes a collection of data that is very large in size?
Large datasets
A company uses previous sales data to predict how many products it will sell next month. What type of analytics is this?
Predictive analytics
You want to show how the temperature changes over the course of a week. Which type of chart would be appropriate?
Line chart
A recipe gives you a specific series of steps to follow to make a meal. In computational thinking, what is this sequence of steps called?
Algorithm
A company wants to see what would happen if it increased its prices by 10%. Instead of changing its real prices, it uses a computer program to test the scenario. What is it using?
Simulation
A social media company collects enormous amounts of information from millions of users every day. The data is too large and complex to handle easily with traditional methods. What is this commonly called?
Big data
A company's data suggests that lowering its price by 5% could increase sales. The system recommends lowering the price. What type of analytics is this?
Prescriptive analytics
You want to investigate whether there is a relationship between hours studied and exam scores. Which visualization would you use?
Scatter plot
Breaking down a problem, looking for patterns, focusing on important information, and creating step-by-step solutions are all parts of what larger concept?
Computational thinking
A scientist creates a simplified computer representation of Earth's climate and then uses it to test what might happen if temperatures increase. Identify the two major concepts being used.
Model and simulation
Thousands of smart thermostats automatically send temperature readings to a company's servers every minute. Identify the technology collecting the information and the type of information being generated.
