nonsense correlation
C1Formal, Academic
Definition
Meaning
A statistical correlation that is mathematically present but has no logical causal relationship; a spurious correlation.
A perceived or calculated relationship between two variables that occurs by coincidence or due to confounding factors, often leading to erroneous conclusions if mistaken for causation. In popular discourse, it can refer to any perceived but meaningless connection.
Linguistics
Semantic Notes
The term combines 'nonsense' (lacking sense or meaning) with 'correlation' (a mutual relationship). It is inherently pejorative, indicating the relationship is not just weak but fundamentally meaningless.
Dialectal Variation
British vs American Usage
Differences
No significant difference in definition. UK academic writing may be slightly more likely to use the synonym 'spurious correlation'. In US business/analytics contexts, terms like 'phantom correlation' or 'false correlation' are common alternatives.
Connotations
In both varieties, the term carries a strong connotation of a methodological or logical error in analysis.
Frequency
Equally rare in everyday speech. More frequent in academic, statistical, and critical thinking contexts in both regions.

Usage
Context Usage
Business
Used critically in data analytics to warn against making investment or strategy decisions based on coincidental data patterns.
Academic
A key concept in statistics, research methodology, and critical thinking courses to highlight logical fallacies.
Everyday
Rare. Might be used humorously or critically to point out a silly perceived connection (e.g., 'Your theory about ice cream sales causing shark attacks is a nonsense correlation.').
Technical
Central in fields like econometrics, epidemiology, and data science to describe relationships caused by lurking variables or pure chance.
Examples
By Part of Speech
verb
British English
- The researcher was careful not to nonsense-correlate the two trends.
- Their methodology seems designed to nonsense-correlate variables.
American English
- The software flagged the result as potentially nonsense-correlating the data sets.
- You can't just nonsense-correlate every uptick in the metrics.
adverb
British English
- The data was correlated nonsensically, producing a misleading graph.
- The variables behaved nonsensically correlated in that model.
American English
- The metrics moved nonsensically correlated during the trial period.
- Their profits rose nonsensically correlated with the national jellybean consumption.
adjective
British English
- They published a paper on nonsense-correlation effects in big data.
- We dismissed it as a nonsense-correlation finding.
American English
- The report contained a nonsense-correlation analysis that skewed the conclusions.
- He was known for his work on nonsense-correlation pitfalls.
Examples
By CEFR Level
- Finding that more ice cream is eaten on sunny days does not mean ice cream causes sunshine. That is a nonsense correlation.
- The graph showed a nonsense correlation between the number of pirates and global warming—it was just a coincidence.
- The apparent link between library budgets and violent crime rates is a textbook nonsense correlation, likely driven by a third variable like municipal funding.
Learning
Memory Aids
Mnemonic
Imagine two people on separate escalators going up at the same time. They are CORRELATED (both going up), but it's NONSENSE to think one is causing the other to rise—the escalator motor is the hidden cause.
Conceptual Metaphor
STATISTICAL RELATIONSHIPS ARE ROADS; A NONSENSE CORRELATION IS A ROAD TO NOWHERE/A DEAD END.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'бессмысленная корреляция' as it sounds odd. Standard term is 'ложная корреляция' (false correlation) or 'спуриосная корреляция' (spurious correlation).
- Do not confuse with 'nonsense' as 'чушь' in isolation; here it's a fixed technical compound.
Common Mistakes
- Using it to describe simply a 'weak correlation'. A nonsense correlation can have a strong mathematical coefficient but still be spurious.
- Pronouncing 'correlation' with stress on the first syllable (/ˈkɒr.ə.leɪ.ʃən/ is incorrect; it's /ˌkɒr.əˈleɪ.ʃən/).

Frequently Asked Questions
It is a specific, strong example of that principle. 'Nonsense correlation' labels a specific observed correlation as being without logical sense, while the phrase 'correlation does not imply causation' is the general warning.
Yes, that's the key point. It can show a very high correlation coefficient (e.g., r=0.95), but the relationship is still spurious due to coincidence or a confounding 'lurking' variable.
It is crucial in any field using statistics to infer conclusions: epidemiology (public health), economics, social sciences, data science, and psychology, to prevent costly or dangerous errors.
A classic humorous example is the strong correlation between the per capita consumption of mozzarella cheese and the number of civil engineering doctorates awarded in the US. They correlate highly but share no causal link.
