Use data from one of the many sample documentsthat come with Fathom.Enter your own databy typing into a case table.Paste data from other applications.Import text files.Dot plot (stacked or unstacked):May be split by adding one or more numeric attributes to the same axis or by dropping a categorical attribute on the other axis. May display dots shaped according to...Line plot:May be split by a categorical attribute on the vertical axis and may display dots shaped according to a legend. You can add attributes to the vertical axis.Histogram (equal width bars):May be split by adding numeric attributes to the same axis or by dropping a categorical attribute on the other axis. May show Frequency (the default), Relative Frequenc...Ntigram (equal area histogram): May be split by adding numeric attributes to the same axis or by dropping a categorical attribute on the other axis.Plotted values:Display any number of computed values with a line perpendicular to the numeric attribute axis of a univariate plot.Plotted functions:Display any functions, f(x), on a graph that has two continuous attributes. For univariate graphs, the x-axis is the axis corresponding to the attribute.t-test to test the meanof a sample against a hypothesized population mean when the population standard deviation is not known. Compute either from summary or raw data.t-test to test the hypothesis that two meansfrom independent samples are equal.Choose either an un-pooled or a pooled estimate of population standard deviation.Compute either from summary or raw data.Given a confidence level, compute the confidence interval for the meanof a population when the standard deviation of the population is unknown. Compute either from summary or raw data.Given a confidence level, compute the confidence interval for a population proportion. Compute either from summary or raw data.Estimate the difference of two means. Given a confidence level, compute the confidence interval for the difference of means for two groups where the groups are specified either by two continuous at...Estimate the difference of two proportions.

All dependent objects update during the drag. 1. Points in plots, bars in histograms and Ntigrams, all portions of a box plot.Dragging changes values of data. 2. Numeric axes.Dragging changes scale or translates axis. 3. Categorical axes.Dragging changes the category order. 4. Slider. Dragging changes slider ...
The appearance of cases in a collection may be changed either directly or through formulas. The “display” attributesover which the user has control are: 1. caption 2. x-position 3. y-position 4. width 5. height 6. icon image (by default, a little gold ball)
All objects may be laid out in a single documentand saved, restored, or printed as such.Individual objects may be viewed in a separate windowif desired.Text objects of any length can be placed anywhere in the document. Text objects support full character formatting and insertion of a suite of mathematical and statistical symbols.Objects may copied as pictures and pasted into other applications, or pasted back into the document as a static record.Statistical Functions
