Ryerson Project Item 16
I see myself as extraverted.
American adults' average (mean) response was 3.70 on a scale of 0 (Disagree) to 10 (Agree). 960 responses have been collected (so far) from 2026-05-01 to 2026-10-27.
Descriptive Statistics

All-Time Distribution
Comparison to Other Items
Based on all-time mean agreement, this item ranks 122 out of 142 qualifying items and is at the 14.2 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 2026-05-01 to 2026-10-27. The estimated change over that period is -0.443 points on a 0 to 10 scale. Regression results place a 95% confidence interval around that observed-period change of [-1.099, 0.213].Regression table
The daily slope annualized over 365.25 days is -0.905 points per year, with a 95% confidence interval of [-2.243, 0.434]. This short-window annualized number is provided for reference, but the observed-period change above is the primary trend estimate.
