Abstract

In 2^k complete factorial experiment, the experiment must be carried out in a completely randomized design. When the numbers of factors increase, the number of treatment combinations increase and it is not possible to accommodate all these treatment combinations in one homogeneous block. In this case, confounding in more than one incomplete block becomes necessary. In this paper, we considered the choice of confounding when k > 2. Our findings show that the choice of confounding depends on the number of factors, the number of blocks and their sizes. When two more interactions are to be confounded, their product module 2 should be considered and thereafter, a linear combination equation should be used in allocating the treatment effects in the principal block. Other contents in other blocks are generated by multiplication module 2 of the effects not in the principal block. Partial confounding is recommended for the interactions that cannot be confounded.

Abstract

Some methods used to analysis between government wage policy on minimum wage saga in Nigeria were considered. Descriptive Statistics, The Ordinary Least Square technique; Correlation Analysis tools were employed to ascertain the significant difference between government wage policy on minimum wage saga in Nigeria. Data were collected for period 1974 – 2000.Our results shows that year of review is negatively and significant on government wage policy on minimum wage saga in Nigeria. Consumer Price Index is negatively and significant on government wage policy on minimum wage saga in Nigeria. Also, there is a perfect negative association on year of review between real minimum wage on government wage policy on minimum wage saga in Nigeria and it is significant, with a perfect positive association year of review between consumer price index on government wage policy on minimum wage saga in Nigeria and it is significant and there is a negative moderate association on real minimum wage between consumer price index on government wage policy on minimum wage saga in Nigeria and it is significant. This study therefore recommends that government should reduce the cost of governance and improve the living standard of workers by fixing a better wage. Finally, diversifying the Nigeria economy is necessary for states to enhance their internally generated revenue and step into creation of employment opportunities and better pay package.
