CompTIA DataX Certification Exam Sample Questions (Q27-Q32):

NEW QUESTION # 27
A data scientist wants to digitize historical hard copies of documents. Which of the following is the best method for this task?

  • A. Word2vec
  • B. Semantic segmentation
  • C. Optical character recognition
  • D. Latent semantic analysis

Answer: C

Explanation:
# Optical Character Recognition (OCR) is the process of converting scanned images or hard copy text into machine-encoded text. It is the standard technique for digitizing printed or handwritten content.
Why the other options are incorrect:
* A: Word2vec is for generating word embeddings from digital text.
* C: Latent Semantic Analysis analyzes semantic structure of existing digital documents.
* D: Semantic segmentation is used in image processing for pixel-wise classification - not text extraction.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 6.3:"OCR converts scanned physical documents into text files that can be searched, analyzed, or stored digitally."
* Practical NLP Applications, Chapter 2:"OCR is a prerequisite for turning printed or written material into structured data suitable for text analytics."

NEW QUESTION # 28
A data scientist wants to predict a person's travel destination. The options are:
* Branson, Missouri, United States
* Mount Kilimanjaro, Tanzania
* Disneyland Paris, Paris, France
* Sydney Opera House, Sydney, Australia
Which of the following models would best fit this use case?

  • A. Principal component analysis
  • B. Linear discriminant analysis
  • C. k-means modeling
  • D. Latent semantic analysis

Answer: B

Explanation:
# Linear Discriminant Analysis (LDA) is a supervised classification method used to predict a categorical target (such as travel destination) based on multiple input features. It models decision boundaries between classes - which is appropriate when predicting a fixed set of destinations.
Why the other options are incorrect:
* B: k-means is unsupervised and doesn't use labeled output like travel destination.
* C: Latent Semantic Analysis is used for extracting relationships from textual data - not categorical prediction.
* D: PCA reduces dimensionality but doesn't classify.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 4.1:"Linear Discriminant Analysis is used when the response variable is categorical and the objective is classification."
* Classification Techniques Guide, Chapter 7:"LDA excels in multi-class prediction when the input data is continuous and the output is a known category."

NEW QUESTION # 29
In a modeling project, people evaluate phrases and provide reactions as the target variable for the model.
Which of the following best describes what this model is doing?

  • A. Sentiment analysis
  • B. Part-of-speech tagging
  • C. Named-entity recognition
  • D. TF-IDF vectorization

Answer: A

Explanation:
# Sentiment analysis refers to using machine learning or NLP techniques to determine the sentiment or emotional tone behind a body of text (e.g., positive, neutral, or negative). When people provide reactions to phrases, the model is learning to associate language with subjective emotion or opinion.
Why the other options are incorrect:
* B: NER identifies entities (e.g., locations, organizations) - not emotions.
* C: TF-IDF is a feature engineering method, not a modeling goal.
* D: POS tagging classifies words by their grammatical function - not sentiment.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 6.3:"Sentiment analysis models associate textual input with subjective labels, such as emotional response or polarity."
* Applied Text Analytics, Chapter 8:"When modeling user reactions to text, sentiment classification techniques are commonly employed."

NEW QUESTION # 30
A data scientist needs to determine whether product sales are impacted by other contributing factors. The client has provided the data scientist with sales and other variables in the data set.
The data scientist decides to test potential models that include other information.
INSTRUCTIONS
Part 1
Use the information provided in the table to select the appropriate regression model.
Part 2
Review the summary output and variable table to determine which variable is statistically significant.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.






Answer:

Explanation:
See explanation below.
Explanation:
Part 1
Linear regression.
Of the four models, linear regression has the highest R² (0.8), indicating it explains the greatest proportion of variance in sales.

Part 2
Var 4 - Net operations cost.
Net operations cost has a p-value of essentially 0 (far below 0.05), indicating it is the only additional predictor statistically significant in explaining sales. Neither inventory cost (p#0.90) nor initial investment (p#0.23) reach significance.


NEW QUESTION # 31
An analyst wants to show how the component pieces of a company's business units contribute to the company's overall revenue. Which of the following should the analyst use to best demonstrate this breakdown?

  • A. Residual chart
  • B. Box-and-whisker chart
  • C. Scatter plot matrix
  • D. Sankey diagram

Answer: D

Explanation:
# A Sankey diagram is ideal for illustrating flow-based relationships, such as how different units or sources contribute to a total. It's especially effective for showing proportions, hierarchy, and decomposition - such as revenue contribution by business units.
Why the other options are incorrect:
* A: Box plots show distributions and spread - not contributions or breakdowns.
* C: Scatter plot matrix explores relationships between numeric variables, not part-to-whole relationships.
* D: Residual charts are diagnostic tools for regression - not for revenue visualization.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 5.5:"Sankey diagrams are useful for visualizing contributions, flows, and proportional allocations across categories."
* Data Visualization Best Practices, Chapter 7:"Sankey charts are preferred when tracking contributions from multiple inputs to a unified output."
