Abstract The study examined the efficacy of instructional outputs of Jigsaw IV and problem-solving approaches of mathematical aspect of statistics. As a quasi-experimental study, one research question and hypothesis were raised for the study with purposively sampled of 35 mathematics teachers and 2,454 SS2 students from senior secondary schools in Lagos State, Nigeria. A 30-item multiple choice questions on mathematical aspect of Statistics was constructed via a test blue print along mean, median, mode, standard deviation and elementary probability. The Cronbach?s Alpha reliability coefficient of the pre and post administration of instrument was 0.86. The statistical tools used for the study included mean, Bar-Chart, One-way ANOVA and Post-Hoc(Scheffe) of version 20 of Special Packages for Social Sciences(SPSS).. Finding showed that there was significant difference in the instructional outputs of students exposed to different groups( F(2,2451)=64.99;P<0.05). The Scheffe Post-Hoc result further revealed that the Jigsaw IV accounted for the significant difference in students? instructional outputs. The discussions of the findings, conclusion and recommendations as embracing the use of Jigsaw strategy to enhance students? learning outcomes, mathematics teachers should learn to improvise, and the strategy should be adopted at all time, with or without instructional materials, among others, were proffered in the study. Keywords- Instructional Outputs, Jigsaws, problem-solving, mathematical aspects, statistics.
