All-Time Distribution
Comparison to Other Items
Based on all-time mean agreement, this item ranks 6 out of 142 qualifying items and is at the 96.5 percentile.
Qualifying items have 100 or more total observations. Higher means indicate more agreement and therefore a higher rank.
Monthly Trend
Observed Trend
Observations suggest unchanging agreement over the observed period, from 2026-05-12 to 2026-10-27. The estimated change over that period is -0.283 points on a 0 to 10 scale. Regression results place a 95% confidence interval around that observed-period change of [-1.023, 0.457].Regression table
The daily slope annualized over 365.25 days is -0.615 points per year, with a 95% confidence interval of [-2.224, 0.994]. This short-window annualized number is provided for reference, but the observed-period change above is the primary trend estimate.
