# Output Tab

You can select the desired output format on the Output tab.

Option | Description
--- | ---
Descriptive Statistics | Select this option to create a table of statistics (valid n, mean, minimum, maximum, standard deviation, skewness, kurtosis) for the selected variables.
Summary graph | Select this option to create a composite summary graph that includes a histogram, box plot, confidence and prediction interval plots along with a table of descriptive statistics.
Normal probability plot | Select this option to create a normal probability plot.
Empirical CDF plot | Select this option to produce a graph that consists of the empirical CDF, the theoretical normal CDF, and 95% confidence bands for the empirical CDF.
Histogram with normal fit | Select this option to produce a histogram with the theoretical normal density function superimposed over the observed frequencies.
Hanging bars histogram | Select this option to produce a hanging bars histogram. The hanging bars histogram offers a "visual test of normality" of the distribution that helps identify the areas of the distribution where the discrepancies (between the observed and expected normal frequencies) occur. While the standard way of presenting the normal distribution fitted to an observed distribution is to overlay the best-fitting normal curve over a histogram, the hanging bars histogram does just the opposite: it suspends the bars representing the observed frequencies for consecutive ranges of values from the best-fitting normal curve. If the investigated distribution can be well approximated by the normal curve, the bottoms of all bars should form a straight, horizontal line.
Box-Cox results | Select this option to display two spreadsheets. The first spreadsheet, Box-Cox transformation, contains the original and transformed variables. The second spreadsheet, Box-Cox statistics, contains information about the transformation parameter (λ) including the lower and upper confidence limit as well as the actual formula used to transform the data.
Send Box-Cox transformation(s) downstream | Select this option to send the Box-Cox transformed variables downstream for further analysis.
User input | Select this option to display the spreadsheet of user-specified options.
