Develop a research question: Can those with income below or above the median be reliably predicted from knowledge of % graduating in 1994 (grad94), average ACT score in 1994 (act94), % taking ACT in 1994 (pctact94), 10 th grade average math score (math93), % who meet or exceed state standards (math94me), 10 th grade average reading score (read93), % who meet or exceed state standards (read94me), 11 th grade average science score (scienc93), & % who meet or exceed state standards (sci94me). Are there any differences between group membership of those with income above the median and those with income below the median? How adequate is the classification of these groups? 2.) Which predictor variables show significant group differences? According to the Tests of Equality of Group Means, all of the variables were significant (which varied from p>.000 to p>.005); hence, all the predictor variables show significant group differences. Yet, as demonstrated by the group means, math93, math94me, read93, read94me, scienc93, & sci94me appear to show greatly significant group
