campbell_st · Answer

well I'd arrange the score in order, lowest to highest

percentiles are 1/10 ths    so 30% = 3/10 * 8 = 2.4

find the score in the 2.4th position

for 90% find the score in the  7.2 position

this is best guess... as I can't ever remember doing percentiles

best guess is 105-100 = 5 * 0.4 = 2   so the 30% percentile is 102

                      200-176 = 24   24*0.2 = 4.8   90% percentile 180.8
