Use the Wilcoxon matched-pairs signed-ranks test procedure with an a = 0.05 significance level to answer the following questions:

1. In 1887, was the median school-year length different for black and white children? How about in 1915?

2. In 1887, was the median salary different for black and white teachers? How about in 1915? Are there any other analyses that you would like to conduct using these data? Explain. Conduct these analyses.

Write a report detailing your assumptions, analyses, findings, and conclusions regarding the impact of Alabama House Bill 504 on the education provided to black and white children.


Before the Civil War, Confederate State constitutions paid little, if any, attention to public education. Nonetheless, blacks were legally prohibited formal schooling, and black literacy was not encouraged in these states. This situation would soon change. For example, the pre–Civil War general educational clauses of Alabama’s constitution were replaced by new ones with very specific language in 1868. The new legislation provided for sufficient funds for a state-wide public school system, while actively discouraging donations from private sources. The new constitution promised equal educational opportunity regardless of race or economic status, but did not mandate racial segregation of public schools. This decision was left in the hands of the state board of education.

In spite of the state’s promise, equal educational opportunity for blacks was not a reality. Nevertheless, blacks made significant educational gains during the next two decades. Unfortunately, storm clouds were brewing as white Democrats began to regain power in the state. The white-authored Alabama state constitution of 1875 severely restricted public funding for education, though it did provide for financing based on a per child basis. Segregated schools became the law of the state. In spite of the legally enforced segregation, black education continued to flourish, while the conditions for whites eroded.

In 1891, Alabama House Bill 504 passed both legislative houses. The constitutionally guaranteed per capita education funding mechanism was preserved, though effectively circumvented, when this bill turned over state education revenues directly to white county officials, who dispersed the money as they saw fit. As a historian, you are interested in evaluating the impact of House Bill 504. Your research has uncovered the average length of the school year and the average monthly teacher salary by race for various counties in Alabama in 1887 (before the passage of the bill) and 1915 (after its passage). The data are presented in the following tables:
