Document Summary

Hr (bpm) measured for group of 15 females + 16 males. Mean of f = sum of all values/#s of females = 1406/15 = 93. 7bpm. Mean of m = 1514/16 = 94. 625 bmp. Not resistant to outliers b/c uses all data. Midpoint value, separating lower & upper halves of dataset. Resistant - doesn"t get pulled by outliers (skew) Boys (16) therefore take 2 midpoints + take mean of them. M value = 8 & 9 (80 & 80bmp) therefore bmp = 80. Easier to see if organize data in numerical order. Multiple modes = list each of them (ex. Given median = no difference but looing at median + mode = difference b/w m. Similar in # of step but doesn"t show entire set of data. J range = 14986 to 5932 = 5932 9054 steps. H range - 11098 to 9857 = 1241 steps.
