Help: Slate Results

There are four sections on the results screen; "Data Summary", "Data Analysis", "Data List", and "Actions".

Data Summary
This section shows a list of all of the variables, along with their average value, minimum, maximum, and standard deviation. Tap on any variable to see graphs representing the data for the variable. This includes a histogram, showing the relative number of values that fall within one of ten divisions of the maximum (e.g. 1-9, 10-19, etc.). Below that, and using the same horizontal value scale, is a standard box plot, showing the median, first and third quartiles, whiskers, two types of outliers (if any), etc. Below that is a graph of averages versus time-of-day, so you can see if the data correlates with the hour of the day (0-23).

Data Analysis
Display Results Graph shows all of the data on a line chart using value vs time. Each variable is assigned a different color. You can zoom and scroll the graph, as well as save a snapshot image to your pictures folder.
Display Correlation Results displays a table of correlation values for every combination of pairs of variables. This table is used to determine statisticaly if one variable affects the other.

Data List
This section simply lists every data point, including the optional comments.

Actions
Delete All Data clears all data results for the current slate. This operation cannot be undone, and normally does not need to ever be done (deleting a slate will also delete the data). You will need to confirm this operation twice.
