NEW QUESTION # 16
Given the following data set:

Which of the following is the best reason for cleansing the data?

A. Corrupt data
B. Redundant data
C. Duplicate data
D. Imputed data

Answer: C

Explanation:
In data management,duplicate datarefers to identical records that appear multiple times within a dataset. Such duplicates can lead to inaccurate analyses, inflated metrics, and erroneous business decisions. Identifying and removing duplicate records is a critical step in the data cleansing process to ensure data quality and reliability.
Option A:Duplicate data
* Rationale:The dataset shows that the record with ID 376, Amount $400, and SKU ABV-DYH appears twice. This repetition indicates the presence of duplicate data, which can skew analysis results if not addressed.
Option B:Imputed data
* Rationale:Imputed data refers to missing or incomplete data that has been estimated or filled in based on other available information. There is no evidence in the provided dataset to suggest that any data has been imputed.
Option C:Redundant data
* Rationale:Redundant data involves unnecessary repetition of data across different fields or tables, leading to inefficiencies. While duplicate data is a form of redundancy, in this context, the specific issue is the exact repetition of entire records, making "duplicate data" the more precise term.
Option D:Corrupt data
* Rationale:Corrupt data refers to data that has been altered or damaged, making it incorrect or unusable.
The dataset provided does not exhibit signs of corruption, such as garbled text or invalid formats.
Reference:The CompTIA Data+ Certification Exam Objectives emphasize the importance of identifying and addressing duplicate data as a key aspect of data cleansing to maintain data integrity and accuracy.

NEW QUESTION # 18
The sales grocery store had an average of $8000 per day. The store introduced several advertising campaigns in order to increase sales. To determine whether the advertising campaigns have been effective in increasing sales, a sample of 64 days of sales was selected, and the sample mean was $8000 per day.
The correct null and alternative hypotheses to test whether there has been a significant increase are

A. Null Population mean is $8000; Alternative; Population mean is greater than or equal to $8000.
B. Null Population mean is $8000; Alternative; Population mean is greater than $8000.
C. Null Sample mean is $8000; Alternative Sample mean is greater than $8000.
D. Null Sample mean is $8000; Alternative Sample mean is greater than or equal to $8000.

Answer: B

Explanation:
Since you are trying to determine whether sales increased above the current average of $8000, the population mean for the null hypothesis is $8000; whereas the mean for the alternative hypothesis is greater than $8000. Hypotheses are always stated in terms of population you are working with, ruling out options A and B.
The test is whether sales are higher than the average of $8000 per day, which rules out option C.
