What are different ways of presenting observed data?

Answer 1

You could present all of the raw data. If there is only a tiny amount, this might not be bad. With larger amounts this is close to useless. You could summarize the data and present it in tables, giving means, medians, modes, and other things for data categorized in various ways. This might be a good preliminary view of the data. You could use any of a number of charts to give visual impact to summarized data. You could do more sophisticated statistical analysis, presumably based on the questions you originally asked that led to the gathering of the data.
