Document Summary
10 s r e y a p f o: categorical; ordinal. Math 214 spring 2012 final exam solutions: a) quantitative; ratio, a) here are two possible histograms, each starting at the minimum (170) but using bin sizes of 20 and 15 respectively. Other answers are possible, but a bin size above 20 is probably too large to get a good picture: 5 # summary: 170 200 235 285 320; iqr = 85 lb, 1. 5 iqr = 127. 5 lb. No player weights are anywhere close to these values, and there are no real gaps in the data, so there are no outliers: bimodal, no. A stem-and-leaf plot would only have three stems (the hundreds place) which would not give you a useful visual picture of the data. (p. s. If you use split stems, you still only end up with four groups of data (150- 199, 200-249, 250-299, 300-349) which would still not give you a useful picture of the data. )
