Although the uploaded filename is STA 112, S1, S4, S6 and S9 visibly include STA 111 labels. S1-2 revise statistics, S3 means, S4-6 frequencies and grouped location, S7-8 dispersion, S9-10 quantiles and skewness, and S11 a grouped-data assignment. These remain in the STA 112 supplement pathway by the user course allocation; the complete underlying methods are taught in the STA 111 section. S69-70 are crowded, partly cropped formula sheets, not a separate verified syllabus.
