Abstract

Everyone at one point or the other ventures into business be it fully or

part-time with the sole aim of making profit amidst different

Government policies, political instability etc. In view of this fact, the

research work uses statistical procedures and models to look at

assessing service delivery in UNILEVER NIGERIA PLC. To this

end, a raw data showing the aggregate sales of four major products of

the organisation was collected for ten consecutive years. The results

obtained showed that the sales are not normally distributed; the rate of

sales of products and the employment are on the increase though the

products have an unequal sales rate. The relationship between the

product sales and employment rate is an almost perfect positive

correlation and the trend line graph is positive.
