The average amount of money the challenger’s incumbent spent is $251,702.4.The calculated median is $78223.5. At the 50 th percentile the amount of money the challenger’s incumbent spent is $ 78,223.5, in other words this value is the middle value of all the different values of the money spent. The calculated mode is zero dollars. In other words, most of the time the challenger’s incumbents did not spend any amount of money. b.

The mean and standard deviation of the challenger campaign spending in 1996 for Republican incumbents is $292435.6 and $ 429151.7, respectively. Therefore, on average the challenger spending in 1996 for Republican incumbents was greater than the challenger spending in 1996 for Democratic incumbents and the standard deviation is much higher as well, meaning a greater variability. 2.) summ totalcontributions, detail gen totalcontributions = partymoney+othcont histogram totalcontributions, addlabels title (" Frequency of Total Contributions") Median= $575,720.9 Mean= $674,289.2 Mode= multimodal Standard Deviation= $674,289.2 The average amount of total contributions to the House incumbents is approximately $ 674,289.2.At the 50 th percentile the total contributions to the House incumbents is $ 78,223.5, in other words this value is the is the middle value of all the different values of the total contributions. 3.) graph bar (mean) partymoney, over(comchair, relabel(1 “Not a Party Comchair” 2 “ Party
