How to read the statistical profile

I present a variety of statistics about Sen. Alvin B. Jackson'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 1 (from interest group ratings). Half a dozen interest groups release ratings of each legislator after each legislative session. I rescale them all from 0 (most liberal) to 100 (most conservative) and average them together, resulting in the numbers reported here.

Ideology score 2 (NOMINATE method) (learn more). Using a widely accepted scaling method, I calculate each legislator's ideology score (called a "NOMINATE" score) after each legislative session. I describe the method here. Scores have no intrinsic meaning; they are useful only for comparing two legislators. A legislator with a higher score is more to the right ideologically of a legislator with a lower scale. In most years, a conservative Republican will have a score above 0; a score close to 100 is extreme.

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.
