CompTIA DataX (DY0-001) — Question 45

A data scientist is working with a data set that covers a two-year period for a large number of machines. The data set contains:

Machine system ID numbers -

Sensor measurement values -
Daily time stamps for each machine
The data scientist needs to plot the total measurements from all the machines over the entire time period. Which of the following is the best way to present this data?

Answer options

• A. Scatter plot
• B. Line plot
• C. Histogram
• D. Box-and-whisker plot

Correct answer: B

Explanation

The correct answer is B, as a line plot effectively shows trends over time, making it ideal for visualizing total measurements across a two-year span. A scatter plot (A) is less effective for showing trends, while a histogram (C) focuses on frequency distribution, and a box-and-whisker plot (D) emphasizes statistical summaries rather than overall trends.
