Answer:
If you are trying to spot an anomalous result from a graph, draw a line of best fit onto your graph, the anomalous result will be the result that is way off the line of best fit/ does not fit the pattern.
If you are looking for an anomalous result within a table, the results should fall with in .1 of each other, if any of the figures do not, then they are the anomalies (anomalous results).
