Document Summary
Math 214 spring 2013 exam 1 solutions: a) 0. 1 the data, so i consider 46 an outlier. [your decision may differ but must be supported by an argument. : using a bin size of 5 (other choices are possible but this is the most obvious): 8. 1 20. 55 = -12. 45, no low outliers. 21. 6 + 20. 55 = 42. 55, 46 is above this point and there is a fairly large jump between 46 and the rest of: iqr = 13. 7, 1. 5 iqr = 20. 55 (quartiles may vary slightly) Snowfall (in. ) s r e t n w i f o r e b m u. 0 5 10 15 20 25 30 35 40 45 50: the distribution is unimodal and skewed right. [if you said so in (b): the mean will be higher than the median. The data are skewed right, and there is a high outlier. Both of those things tend to increase the mean relative to the median.
