I present a variety of statistics about Sen. Darin G. Peterson's service in the Utah legislature. I highlight differences from chamber averages using little green and red arrows. The number of arrows is statistically determined. More arrows indicate a larger difference compared to the chamber average, in relation to how much diversity there is among legislators on this metric. If all legislators introduce exactly 5 bills, then a legislator who introduces 10 is very different; if legislators vary wildly in how many bills they introduce (but the average is still 5), then a legislator who introduces 10 bills may be less different from average. The standard deviation measures this diversity.
/
Three arrows mean that the legislator is significantly different from average (i.e. at least two standard deviations from the mean, placing the legislator in the top/bottom 2% or so)./ Two arrows mean that the legislator is somewhat different from average (i.e. at least one standard deviation from the mean, placing the legislator in the top/bottom 16% or so)./ One arrow indicates that the legislator is only slightly different from average (i.e. one-third standard deviation from the mean). A single arrow indicates a very small difference; don't make too much of it.| 2007 | 2008 | ||

| Bills floor sponsored. A "floor sponsor" is like a secondary sponsor of a bill. After a bill passes the sponsor's chamber, its sponsor needs to find a "floor sponsor" in the other chamber to usher it through the other chamber. | |||

| Missed votes (learn more). Usually missed votes occur because of competing obligations within the legislature, not because the legislator has left the capitol. | |||

| "Nay" votes (learn more). Most floor votes pass by overwhelming majorities, since unpopular bills get weeded out long before they reach the floor. As a result, "nay" votes are rare. | |||

| Ideology score (NOMINATE method) (learn more). Using W-NOMINATE algorithm developed by Congressional scholars, I calculate each legislator's relative ideology after each General Session. I describe the method here. Scores have no intrinsic meaning. They are only relative: A legislator with a higher score is to the right ideologically of a legislator with a lower scale. Scores may be compared only within a single chamber and a single year. In most years, a conservative Republican will have a score above 0; a score close to 100 is extreme. | |||
| Contact me for scores. They get misinterpreted often enough that I now provide them only to political scientists. | |||

| Party support score (overall) (learn more). How consistently does Sen. Peterson support his/her party? That is, what percentage of the time does the legislator vote with the majority of the other members of his/her party? Scores are usually easily above 90%. | |||
| Score (overall) | 98% | 97% | |

| Party support score (party-line only) (learn more). This is the same as the "raw" party support score, but we look only at party-line votes when calculating this. A "party-line" vote occurs when the majority of Democrats votes against the majority of Republicans. Although party-line votes are rare, looking at the legislator's party support score in this setting can be revealing. | |||
| Score (party-line only) | 93% | 94% | |
| Chamber average | 83% | 85% | |
