Study Notes
Statistical Ranges Over Time
- Statistical data covers several years from 1990 to 2010, focusing on numerical ranges.
- Ranges indicate variances within specified intervals, suggesting trends or fluctuations.
Data for 2010
- Multiple ranges indicate minimal variability centered around zero:
- [.0035, .0035] suggests a precise value or a narrow threshold.
- [.0025, .0035] and [.0015, .0025] show increasingly tighter ranges, indicating improved accuracy or less variability.
- Negative range [-.0005, .0005] signifies a balance around zero, demonstrating negligible change.
Data for 2000
- Data reveals a downward trend with negative ranges:
- Total changes fall within intervals such as [-.0015, -.0005] and [-.0025, -.0015], reflecting a decline over this period.
- The more extensive negative range [-.0035, -.0025] indicates significant downward shifts in values compared to previous years.
Data for 1990
- Noticeable negative ranges highlight a potential worsening situation:
- The range of [-.0045, -.0035] indicates a strong adverse trend.
- Extended negative intervals, like [-.0055, -.0045], suggest substantial deterioration over this decade.
Overall Trends
- As years progress from 1990 to 2010, there is a shift from broader negative ranges to tighter and more neutral intervals.
- The progression from negative values to a narrow positive threshold in 2010 indicates a potential recovery or stabilization in the metrics measured.
