"Assessment of the correlation between Gross Fixed Capital formationand the economic growth rate of UK, Japan, Nigeria, Brazil:Gross fixed capital formation is significantly refers to the net investment. It is the main elementof expenditure method of calculating the GDP. It measures the total increment in the fixedcapital. It includes expenditure on land development such as fences, roads, ditches andmachinery, equipment purchases.

It ismore focused on value added rather than sales(The World Bank, 2013).However the relationship between the two is based on the data set provided by some trustablestatistical institutes. The correlation and regression analysis has been done by the researcher onthe provided data of 15 years of the mentioned countries. This analysis will be capable toperform the role of detecting the relationship between the variables.Japan: The correlation analysis of Japan is based on the data set of the 15 years.
