Document Summary

Working with box-and-whisker plots: the data below shows the number of raisins in each of 14 boxes (1/2 oz. ) of three. Page 1 of 2 different brands of raisins: (8 points) 25, 26, 26, 26, 26, 28, 27, 26, 25, 28, 24, 28, 27, 25: compute the median, lower and upper quartiles, and interquartile range for each data set. Note: we are using the following definitions in this assignment and course: when there"s an odd number of observations in a group, the median is the middle number. When there"s an even number of observations in a group, the median is (n+1)/2. The interquartile range, iqr, is q3 q1, where q3 is the median number of the top 50% and q1 is the median of the bottom 50% of scores. (we are not using fences. ) The median of the sun tyrant data set is 26. The median of the sun acrid data set is 28.
