Compared to:
Air Quality Index
The American Lung Association (ALA) assigns grades A-F to counties (A=1; B=2; C=3; D=4; F=5), based on average annual number of days that ozone levels exceeded U.S. standards during the three year measurement period. The five-point grading scale was used for the distribution (Green = <2; Yellow = 2 - 3; Red = >3). The air quality data is collected by the EPA and summarized by the ALA.
Prior Value
(5)
Prior Value compares a measured value with the previously measured value. Confidence intervals were not taken into account in determining the direction of the comparison.
Trend
This comparison measures the indicator’s values over multiple time periods.<br>The Mann-Kendall Test for Statistical Significance is used to evaluate the trend<br>over 4 to 10 periods of measure, subject to data availability and comparability.
