S.5 Applied Mathematics Revision Test – Statistics, Vectors and Errors (Term 1, 2020)

This two-page revision paper is for Senior 5 learners taking Applied Mathematics Paper 2 (P425/2). It was set by a school mathematics department in 2020. Most of the questions cover descriptive statistics. Learners find the mean, mode, median, standard deviation, interquartile range and percentiles from grouped and ungrouped data. They also draw cumulative frequency curves and ogives, and combine the statistics of two data sets. Other questions cover vectors, including resultants, magnitudes, perpendicular vectors and the angle between two vectors. A final group of questions deals with numerical errors: maximum possible error, percentage error and the range in which an exact value lies. Learners can use the paper for practice and self-assessment.
