Part 10: Academic achievement, (average test scores in reading and mathematic) and the number of suspensions for each school under study

Table 5: Correlation between total numbers of middle school suspensions
For school year 2005-2006 and academic achievement,
(Average test scores in reading and mathematic)

Correlation of total numbers of suspensions to the	Value of r	Level of Significance	Interpretation

Table 5 shows that all of the categories in reading and mathematics achievements average scores were slightly affected by the total number suspensions. It reveals that all academic achievements have significant relationship to the total number of suspensions. It also shows that below and average have negative correlations. This means that suspensions of students are good for the results of achievements of every school in Columbia.
