Document Summary
Stats: science of collecting, analyzing, & interpreting data from sample to draw conclusions about population. Pop: complete collection of all items in a set & represented by n . 1 student absent from class means no pop. Parameter: data from pop where value typically unknown. Census: procedure of systematically acquiring/recording info about members of pop. 1st quartile: = quartile(data,1) pop = bigger, complete sample= subset, smaller than pop. The left is 30 + iqr of 10 = 40. Mode: how many times #"s occur [sometimes more than 1 so look carefully!! To find q1 & q3 if not given type = quartile(data,1) = quartile(data,3) What to list: highest (max), lowest (min), range (max-min), sqrt (#of sample), opt bin width (range/sqrt(#of sample), rounded # of bin width up. Then highlight data insert chart histogram chart customize histogram bucket size and type in the opt bin # that"s rounded. Now you"ll have correct histogram and bin width!
