When a Strong Correlation Does Not Measure Business Growth

A correlation of 0.876 sounds like powerful evidence that government support helps businesses grow. But in a 2023 paper on small businesses in Asaba, Nigeria, that number comes from comparing survey response scores with how often each answer appeared. The distinction changes what the result can tell a business owner.
C. G. E. Salami, Sunny E. Ekakitie and L. O. Ebinim set out to examine entrepreneurship policy interventions, monetary policy and business development. They described a questionnaire survey using convenience sampling, with 291 questionnaires distributed and 272 returned for analysis. This was an observational survey, without an experimental policy intervention.
The authors reported strong positive relationships between both policy categories and entrepreneurial growth. Their calculation, however, paired five response weights with five response frequencies. It did not pair each business’s exposure to support with its measured growth. A high correlation here reflects the distribution of agreement across answer categories; it cannot establish the claimed relationship between policy and business performance.
There are further reporting problems. Although the methods describe small-business staff, the abstract refers to medical personnel and health workers. The results explain answers in terms of hospital service quality and employee empowerment. These inconsistencies leave the surveyed population and the meaning of the responses uncertain.
Convenience sampling also limits representativeness. The significance calculations use a sample count of 15, despite the correlation tables containing five category pairs. Even a correctly measured association would not, by itself, show that policy caused expansion. Recommendations about lending rates and infrastructure therefore go beyond what this analysis demonstrates.
For anyone assessing growth support, the useful lesson is to inspect what the numbers connect. Agreement with a questionnaire statement is different from evidence of improved margins, sales or delivery capacity. This paper raises relevant policy questions, but its reported calculations cannot establish which support measures improve business growth.
