What is the best graph you can use to portray data across time?
Use a line chart or an area chart to show changes that are continuous over time. Line charts are the most effective chart for displaying time-series data.
What is out of range data?
Out of range is sometimes abbreviated to OOR and there are two main reasons for a result being classified as OOR: A result that is too far above or below the statistically reliable range for the selected need. A result for a year group where there is insufficient data to make reliable comparisons for that need.
What plot is useful for displaying data values taken at different time points?
A box plot can be useful when a distribution of values need to be plotted for each time period; each set of box and whiskers can show where the most common data values lie.
