Quartiles. Quartile deviations and semi-interquartile ranges will be the mains points that you (student) will be focused in this e-tivity; you must be able to
understand the steps to follow and arrive to know well the ways to follow until you find that quartile Q1, Q2 and Q3,and determine their position on the graphs
with their meanings and their interpretations.
Quartiles Deviations:
Similarly, as quartiles are now known, you will follow the steps of deducing the mechanism or technics helping you to determine semi-interquartile range then quartile deviation by applying the appropriate formula studied to determine those parameters,(see, Unit 4.1), in the Lecture notes. This quiz aims to guide you to review how to calculate the quartiles and deduce through the appropriate formulae the quartile deviation.
