    abstract = {The study applied statistical methods to obtain the relationship between the petrol priceand inflation.
Since the prices of petrol 93 and petrol 95 differ, separate relationships were sought. In determining the
relationship between petrol price and inflation, a time series model for the petrol price and inflation was
developed. The study used secondary data sourced from the Department of Energy, South Africa. The data for
petrol price was obtained from the published report that is from the Department of Energy and Statistics South
Africa (Stats SA) while for inflation data, stats SA provided them. The Pearson’s correlation coefficient was
used to measure the strength of the statistical association between petrol and inflation. For petrol 93 and 95,
the correlation coefficients were found to be 0.055 and 0.059. This means that a weak but positive relationship
between inflation and petrol price was found. Based on the study it is concluded that inflation has a minor
impact on the petrol price.}
