How to read the statistical profile

I present a variety of statistics about Rep. Val L. 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.

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.

"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 (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.
