13 Median = th value 2 M C1 C1 for correct formula for median Lower quartile = th value Upper quartile = th value So if you have a table with 12 values C1 for correct formula for LQ C1 these will be the 6th, 3rd and 9th values. C1 for correct formula for UQ C1 M1, for values for UQ and LQ with a difference of 7 M1 C1 for explanation of difference in relation to range in C1 this context These can be adapted as long as rows are added equally in each section (see example below).
