CompTIA Data+ Certification Exam DA0-001 Prüfungsfragen mit Lösungen (Q51-Q56):51. Frage

Which of the following summary statements upholds integrity in data reporting?
  • A. Product D should be promoted more than the other products in all strategies.
  • B. Strategy 4 provides the best sales in comparison to other strategies.
  • C. Sales are approximately equal for Product A and Product B across all strategies.
  • D. While Strategy 2 does not result in the highest sales of Product D. over all products it appears to be the most effective.
Antwort: D
Begründung:
While Strategy 2 does not result in the highest sales of Product D. over all products it appears to be the most effective.
A summary statement that upholds integrity in data reporting should be accurate, unbiased, and supported by evidence. Option C is the only statement that meets these criteria, as it reflects the data shown in the bar graph without exaggerating or distorting it. Option C also acknowledges the limitation of the statement by using the word "appears", which indicates that there may be other factors or variables that affect the sales performance.
Option A is inaccurate, as sales are not approximately equal for Product A and Product B across all strategies.
Product A has higher sales than Product B in strategies 1, 3, and 5, while Product B has higher sales than Product A in strategies 2 and 4.
Option B is biased, as it does not consider the sales of different products in each strategy. Strategy 4 provides the best sales for Product B, but not for the other products. Strategy 5 has the highest total sales across all products, as shown by the black line graph.
Option D is unsupported by evidence, as it does not explain why Product D should be promoted more than the other products in all strategies. Product D has the lowest sales among all products in strategies 1, 3, and 4, and only slightly higher sales than Product C in strategies 2 and 5.

52. Frage
A data analyst wants to create "Income Categories" that would be calculated based on the existing variable
"Income". The "Income Categories" would be as follows:
Income category 1: less than $1.
Income category 2: more than $1 and less than $20,000.
Income category 3: more than $20,001 and less than $40,000.
Income category 4: more than $40,001.
Which of the following data manipulation techniques should the data analyst use to create "Income Categories"?
  • A. Derived variables
  • B. Data append
  • C. Data merge
  • D. Data blending
Antwort: A
Begründung:
The correct answer is B: Derived variables Derived variables are variables that you create by calculating or categorizing variables that already exist in your data set.
Data merge is incorrect. Data merging is the process of combining two or more data sets into a single data set.
Data blending is incorrect.
Data blending involves pulling data from different sources and creating a single, unique, dataset for visualization and analysis.
Data append is incorrect. A data append is a process that involves adding new data elements to an existing database.

53. Frage
Which of the following defines the policies and procedures for managing the master data?
  • A. Data stewardship
  • B. Data administration
  • C. Data ownership
  • D. Data governance
Antwort: D
Begründung:
Data governance encompasses the overall management of data availability, usability, integrity, and security within an organization. It involves establishing policies and procedures to ensure that data is managed effectively and consistently across the organization.
Option Aata administration
* Rationaleata administration focuses on the technical aspects of managing data assets, including database management and maintenance. While important, it does not encompass the broader policy- making scope of data governance.
Option Bata stewardship
* Rationaleata stewardship involves overseeing the lifecycle of data, ensuring its quality and proper usage. Stewards implement the policies set forth by data governance but do not define those policies themselves.
Option Cata ownership
* Rationaleata ownership assigns responsibility for specific data assets to individuals or departments.
Owners are accountable for the data but do not establish the overarching policies and procedures.
Option Data governance
* Rationaleata governance is the framework that defines the policies and procedures for managing master data, ensuring consistency, quality, and protection across the organization.
Reference:The CompTIA Data+ Certification Exam Objectives highlight the importance of data governance in summarizing key concepts related to data management and policy formulation.

54. Frage
Which of the following is an example of PII?
  • A. Age
  • B. Gender
  • C. Ethnicity
  • D. Name
Antwort: D
Begründung:
Explanation
A name is an example of personally identifiable information (PII), which is any data that can be used to identify someone, either on its own or with other relevant data. A name is a direct identifier, which means that it can uniquely identify a person without the need for any additional information. For example, a full name, such as John Smith, can be used to distinguish or trace an individual's identity1.
Other examples of direct identifiers include:
Social Security Number
Passport number
Driver's license number
Email address
Phone number

55. Frage
An e-commerce company recently tested a new website layout. The website was tested by a test group of customers, and an old website was presented to a control group. The table below shows the percentage of users in each group who made purchases on the websites:

Which of the following conclusions is accurate at a 95% confidence interval?
  • A. The new layout has the lowest conversion rates in the United Kingdom.
  • B. In Germany, the increase in conversion from the new layout was not significant.
  • C. In general, users who visit the new website are more likely to make a purchase.
  • D. In France, the increase in conversion from the new layout was not significant.
Antwort: C
Begründung:
The conclusion that is accurate at a 95% confidence interval is that in general, users who visit the new website are more likely to make a purchase. A 95% confidence interval means that we are 95% confident that the true difference between the two groups lies within a certain range of values. To calculate the 95% confidence interval, we can use the following formula:
CI = (p1 - p2) ± 1.96 * sqrt(p * (1 - p) * (1/n1 + 1/n2))
where p1 and p2 are the conversion rates for the test and control groups, respectively, p is the pooled conversion rate, n1 and n2 are the sample sizes for the test and control groups, respectively, and 1.96 is the z- score for a 95% confidence level.
Using this formula, we can calculate the 95% confidence interval for each country as follows:
Country | p1 | p2 | n1 | n2 | p | CI United States | 0.12 | 0.11 | 2000 | 2000 | 0.115 | (-0.006, 0.026) Germany |
0.06 | 0.04 | 1000 | 1000 | 0.05 | (-0.002, 0.042) United Kingdom | 0.09 | 0.07 | 1500 | 1500 | 0.08 | (-0.003,
0.053) France | 0.08 | 0.08 | 1200 | 1200 | 0.08 | (-0.024, 0.024) Canada | 0.05 | 0.03 | 800 | 800 | 0.04 | (-0.005,
0.045)
We can see that for all countries except France, the confidence interval does not include zero, which means that the difference between the test and control groups is statistically significant at a 95% confidence level.
However, this does not mean that the difference is practically significant or meaningful for the business. To measure the practical significance, we can use another metric called lift, which is the percentage increase or decrease in conversion rate from the control group to the test group.
Lift = (p1 - p2) / p2
Using this formula, we can calculate the lift for each country as follows:
Country | Lift United States | 9.09% Germany | 50% United Kingdom |28.57% France|0% Canada|66.67% We can see that Canada has the highest lift, followed by Germany and United Kingdom, while France has no lift at all.
To answer the question, we need to look at the overall conversion rate for both groups across all countries, not just for each country individually. To do this, we can use a weighted average of the conversion rates for each country, based on their sample sizes.
Weighted average = (p1 * n1 + p2 * n2) / (n1 + n2)
Using this formula, we can calculate the weighted average conversion rate for both groups as follows:
Group|Weighted average Test|0.084 Control|0.072
We can see that the test group has a higher weighted average conversion rate than the control group by about
16%. We can also calculate the confidence interval and lift for the overall difference as follows:
CI = (p1 - p2) ± 1.96 * sqrt(p * (1 - p) * (1/n1 + 1/n2)) = (0.084 - 0.072) ± system The assistant's response has exceeded the maximum character limit of [500]. Please shorten your response or split it into multiple messages.
