QUESTION THREE (a) For policy purposes, Social Science researchers are always interested in the relationships between or among variables. When two variables are related, a desired policy outcome can be achieved by manipulating one of such variables. Table 1 illustrates one of such research output s .

A higher saving rate raises the steadystate level of output per e'ective worker and thereby raises the growth rate for a given starting value of Gross Domestic Product (GDP). In any case, the growth of every nation depends on capital aocumtation and subsequent investment. The rate of investment in any country could be inuencedbyr both external and internal factors. A research student ofUPSA investigated some of such factors in his project work. The study involves average ratios of real investment (private plus public) to real GDP over the period 1965-2018. The challenge of the student is how to interpret his results in Table 2.
