CompTIA Data+ Certification Exam Sample Questions (Q117-Q122):

NEW QUESTION # 117
A data analyst has been asked to create an ad-hoc sales report for the Chief Executive Officer (CEO).
Which of the following should be included in the report?

  • A. YTD total sales.
  • B. Line-item SKU numbers.
  • C. The sales representatives' home addresses.
  • D. The customers' first and last names.

Answer: A


NEW QUESTION # 118
Given the following customer and order tables:
Which of the following describes the number of rows and columns of data that would be present after performing an INNER JOIN of the tables?

  • A. Eight rows, seven columns
  • B. Nine rows, five columns
  • C. Five rows, eight columns
  • D. Seven rows, eight columns

Answer: D

Explanation:
Explanation
This is because an INNER JOIN is a type of join that combines two tables based on a matching condition and returns only the rows that satisfy the condition. An INNER JOIN can be used to merge data from different tables that have a common column or a key, such as customer ID or order ID. To perform an INNER JOIN of the customer and order tables, we can use the following SQL statement:

This statement will select all the columns (*) from both tables and join them on the customer ID column, which is the common column between them. The result of this statement will be a new table that has seven rows and eight columns, as shown below:

The reason why there are seven rows and eight columns in the result table is because:
There are seven rows because there are six customers and six orders in the original tables, but only five customers have matching orders based on the customer ID column. Therefore, only five rows will have data from both tables, while one row will have data only from the customer table (customer 5), and one row will have no data at all (null values).
There are eight columns because there are four columns in each of the original tables, and all of them are selected and joined in the result table. Therefore, the result table will have four columns from the customer table (customer ID, first name, last name, and email) and four columns from the order table (order ID, order date, product, and quantity).


NEW QUESTION # 119
Which of the following data types is best for representing count data?

  • A. Continuous
  • B. Referential
  • C. Sequential
  • D. Discrete

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Count data refers to data that represents the number of occurrences of an event or the number of items in a set, which are whole numbers (integers). Understanding the nature of data types is crucial for accurate data analysis and representation.
* Discrete Data: This type of data consists of distinct, separate values. Discrete data is countable and often represents items that can be counted in whole numbers, such as the number of customers, defects, or occurrences. Since count data involves whole numbers, discrete data is the most appropriate representation.
* Referential Data: This pertains to data that establishes relationships between tables in a database, often using keys. It is not related to counting occurrences.
* Sequential Data: This involves data that follows a specific order or sequence, such as timestamps or ordered events. While it indicates order, it doesn't inherently represent count data.
* Continuous Data: This type of data can take any value within a range and is measurable rather than countable, such as height, weight, or temperature. Continuous data is not suitable for representing count data, as counts are discrete by nature.
Therefore, Discrete data is the best choice for representing count data, as it accurately reflects whole number counts of occurrences or items.


NEW QUESTION # 120
An analyst conducted a preliminary analysis for a data set and identified several patterns and anomalies. Which of the following analysis techniques did the analyst use?

  • A. Trend analysis
  • B. Link analysis
  • C. Performance analysis
  • D. Exploratory analysis

Answer: D

Explanation:
Comprehensive and Detailed In-Depth
Exploratory Data Analysis (EDA) is an approach used by analysts to analyze data sets to summarize their main characteristics, often employing visual methods. The primary goal of EDA is to discover patterns, spot anomalies, test hypotheses, and check assumptions through statistical graphics and other data visualization tools.
Option A:Performance analysis
Rationale:Performance analysis focuses on assessing the efficiency and effectiveness of a system, process, or individual. It involves measuring key performance indicators (KPIs) to determine how well objectives are being met. This type of analysis is not primarily concerned with identifying patterns or anomalies in data sets.
Option B:Exploratory analysis
Rationale:Exploratory analysis involves examining data sets to uncover underlying structures, extract important variables, detect outliers, and test underlying assumptions. By using statistical tools and visualization techniques, analysts can identify patterns andanomalies, making it a crucial first step in data analysis.

Option C:Link analysis
Rationale:Link analysis is a data analysis technique used to evaluate relationships or connections between nodes in a network. It's commonly used in fields like criminology, fraud detection, and network analysis to identify relationships between entities. While valuable, it is more specialized and not typically used for general pattern and anomaly detection in data sets.
Option D:Trend analysis
Rationale:Trend analysis involves analyzing data to identify patterns or trends over a specific period. It is used to predict future movements based on historical data. While it focuses on patterns, it is specifically concerned with temporal changes rather than a broad examination of data for various patterns and anomalies.
