CompTIA DataX (DY0-001) — Question 68

An analyst is examining data from an array of temperature sensors and sees that one sensor consistently returns values that are much higher than the values from the other sensors. Which of the following terms best describes this type of error?

Answer options

• A. Synthetic
• B. Systematic
• C. Heteroskedastic
• D. Idiosyncratic

Correct answer: B

Explanation

The correct answer is 'Systematic' because this type of error consistently affects the sensor's readings in a predictable manner, leading to biased results. The other options do not accurately describe this consistent deviation: 'Synthetic' refers to artificially created data, 'Heteroskedastic' pertains to varying variances in data, and 'Idiosyncratic' describes errors unique to individual observations rather than a consistent pattern.
