Computational Thinking Quiz 2

1. What is categorizing a set of photographs by grouping them into similar piles based on their dates mean?

Data collection

Data manipulation – rearranging

Data analysis

Data visualization

2. What is the first step while trying to solve a problem computationally?

Tackle the complex problem as is, without breaking it into subproblems

Focus on how the problem needs to be solved rather than what needs to be solved

Accurately identify and understand the actual problem that needs to be solved

Guess what the solution might be

3. Which of the following is true for algorithm writing?

An algorithm consists of an ordered sequence of instructions

There can be only one algorithm for a problem

Knowledge of computers is essential to write an algorithm

Algorithms prevent replication of a process

4. Data visualization uses the following methods:

Transformation and recognizing similar patterns

Flowcharts, graphs, and images

Quantitative and qualitative approaches

Sorting and rearranging

5. Which of the following is true for abstraction?

Knowledge of computers is essential to do abstraction

It helps us gain additional information about a problem

It helps us focus on the important parts of a problem

It helps us find patterns

6. Which of the following needs to be kept in mind while designing an algorithm?

More than one solution is possible

It should not look like a recipe

It is correct the first time

The appropriate programming language needs to be used

7. What is data visualization?

Making sense of data, finding patterns, and drawing conclusions

Depicting and organizing data in appropriate graphs, charts, words, or images

The process of gathering appropriate information

Breaking down tasks into smaller, manageable parts

8. Which of the following is true for patterns?

Only shapes and colors can form patterns?

Irregular relationships between elements lead to very good patterns

Patterns consist of non-repeating sequences

More than one pattern can exist in solutions to problems

9. Which of the following is not a computational thinking practice?

Pattern identification

Abstraction

Programming

Decomposing

10. What is data analysis?

Making sense of data, finding patterns, and drawing conclusions

Depicting and organizing data in appropriate graphs, charts, words, or images

Breaking down tasks into smaller, manageable parts

The process of gathering appropriate information

11. Which of the following contains a pattern?

I have two ears

All humans have ears.

My friend wears earrings

My friend has two ear

12. What do data analysis approaches include?

Sorting and rearranging

Quantiative and qualitative approaches

Flowcharts, graphs, and images

Transformation, and recognizing similar patterns

13. Which of the following will happen if we do not look for patterns?

We will not be able to decompose the problem

Our solution might be incorrect and inefficient

Our solution will be inefficient

We will fail to solve the problem
