An upward trend on the R chart indicates that the process variability is steadily increasing. This is because the R chart measures the variability or dispersion of the process data over time, and if this variability is increasing, the R values will also increase over time, resulting in an upward trend on the R chart. The other options do not accurately reflect an increase in process variability.
