The first draft of the RHP Statistics program just gathered data and presented the results with a graph. To keep track of this information I put it in a database table. Now, all you see is the raw numbers, but I'll add the graphs, trend analysis, harmonic smoothing, and moving averages to this program later. BTW, the old graphs are still available.
There is no trend in the data. The mean and median are both flat. The distribution is skewed left of center.
There have been many students involved in our project that have increased their ratings, but these are individual scores. The constant influx of new members with low ratings keeps the overall flat.
With the new database table we will be able to plot these numbers in a time series where we can determine trend, cycle, seasonal movement, and randomness.
