All-Time Distribution
Comparison to Other Items
Based on all-time mean agreement, this item ranks 6 out of 135 qualifying items and is at the 96.3 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 2026-09-09. The estimated change over that period is -0.232 points on a 0 to 10 scale. Regression results place a 95% confidence interval around that observed-period change of [-1.064, 0.600].Regression table
The daily slope annualized over 365.25 days is -0.706 points per year, with a 95% confidence interval of [-3.238, 1.827]. This short-window annualized number is provided for reference, but the observed-period change above is the primary trend estimate.
