ABSTRACT
A regression line drawn through a scatterplot shows the overall pattern of the data points using a single straight line. The line is an attempt to give a best estimate of all the data points. This line is usually referred to as a "best fit line". It is drawn to minimize the distance between it and each data point. Scattered dots indicate exceptions to the trend suggested by the regression line. In addition, scatterplots with widely scattered dots, without a clear pattern, will represent smaller correlations. This chapter estimates the percentage of children living below the federal poverty level in each state from the poverty estimate files prepared by the US Bureau of the Census [and examines their relationship with child mortality rates]. In view of the association demonstrates between child deprivation levels and mortality risk, failure to identify and ameliorate conditions in which families possess inadequate resources may have serious consequences for children's health and for their life chances".
