... Last time, we calculated a standard deviation for your ball-rolling data. You calculated the mean and standard deviation for a 16 foot run with a large ball, in which the values were 2.96, 3.01, 3.04, and 2.97 sec. What we now want to know is whether the same 16 foot run, for a small ball, gives the ...

Section 11.2 Notes
... Statisticians use measures of position to describe where specific values fall within a data set. Quartiles are three position measures that divide a data set arranged in ascending order into four groups, each containing about 25% of the data. The median marks the seconf quartile Q2 and seaparates th ...
