Scan All the Data
You have a certain amount of data. A brief note of warning
is in order before you continue. The current data should not
be regarded as final. As your analysis progresses, you may find
that the data are not enough since some of the specified phenomena
cannot be identified. On this occasion, you need to repeat the
procedures you went through in Stage 6 and gather more data.
At the end of the last stage you have turned your data into
computer files. Even so, the data still consist of only raw
material that needs further processing. You have to go over
all the data and examine them closely so that you will be
finally in a position to answer the questions you have raised.
