CompTIA Data+ Exam 認定 DA0-002 試験問題 (Q55-Q60):

質問 # 55
Given the following dataset:
Day
Number of Guests
Monday
455
Tuesday
346
Wednesday
382
Thursday
563
Friday
887
Saturday
934
Sunday
346
Which of the following is the mode?

A. 0
B. 1
C. 2
D. 3

正解：C

解説：
This question falls under theData Analysisdomain, focusing on statistical measures. The mode is the value that appears most frequently in a dataset.
* Monday: 455
* Tuesday: 346
* Wednesday: 382
* Thursday: 563
* Friday: 887
* Saturday: 934
* Sunday: 346
The value 346 appears twice (Tuesday and Sunday), while all other values (455, 382, 563, 887, 934) appear once. Thus, the mode is 346.
* Option A: 346- Correct, as it's the most frequent value.
* Option B: 446- Incorrect, as 446 doesn't appear in the dataset.
* Option C: 455- Incorrect, as 455 appears only once.
* Option D: 559- Incorrect, as 559 doesn't appear in the dataset.
The DA0-002 Data Analysis domain includes "applying the appropriate descriptive statistical methods," and the mode is a fundamental measure of central tendency.

A. Data warehouse
B. Data mart
C. Data lake
D. Data silo

質問 # 58
A data analyst is creating a pivot table for a large dataset for an upcoming board meeting. Which of the following is the purpose of the pivot table?

A. To retrieve and clean data from several sources
B. To summarize and analyze the data
C. To organize the data for reporting
D. To visualize the data in a dashboard

正解：B

解説：
This question pertains to theData Analysisdomain, focusing on the purpose of a pivot table. Pivot tables are a tool for summarizing and analyzing data, often used in preparation for reporting.
* To visualize the data in a dashboard (Option A): Pivot tables summarize data but aren' tvisualizations; charts in dashboards might be created from pivot tables.
* To retrieve and clean data from several sources (Option B): Retrieving and cleaning data is part of data preparation, not the purpose of a pivot table.
* To summarize and analyze the data (Option C): Pivot tables aggregate and summarize data (e.g., by calculating sums, averages) and allow for analysis (e.g., filtering, grouping), which is their primary purpose.
* To organize the data for reporting (Option D): While pivot tables can help organize data, their main purpose is summarization and analysis, not just organization.
The DA0-002 Data Analysis domain includes "applying the appropriate descriptive statistical methods," and pivot tables are a key tool for summarizing and analyzing large datasets.

質問 # 59
Which of the following best enables the retrieval and manipulation of data that is stored in a relational database?

A. JavaScript
B. XML
C. SQL
D. Excel

解説：
This question pertains to theData Concepts and Environmentsdomain, focusing on tools for interacting with relational databases. The task is to identify the best method for retrieving and manipulating data.
* XML (Option A): XML is a data format, not a language for retrieving or manipulating database data.
* SQL (Option B): SQL (Structured Query Language) is specifically designed for querying and manipulating data in relational databases (e.g., SELECT, UPDATE), making it the best choice.
* Excel (Option C): Excel can analyze data but isn't designed for direct database manipulation.
* JavaScript (Option D): JavaScript is a programming language for web development, not optimized for relational database operations.
The DA0-002 Data Concepts and Environments domain includes understanding "different types of databases," and SQL is the standard language for relational database operations.
