What it does
NCSS Data Analysis supplies statistical and graphics procedures for research, forecasting and business-data analysis. It imports spreadsheet and statistical formats, supports filtering or transformation, and presents selected reports and plots through a procedure-based desktop workflow.
NCSS separates the dataset, procedure settings and results into three windows. Enter or import data in the Data window, then use the procedure search or menu to choose an analysis. The output gallery keeps multiple runs together, and plot settings can be saved for later reports.
For a two-group comparison, open Analysis > T-Tests > Two-Sample T-Test. Reset the procedure, choose the measured column under Response Variable(s), and select the grouping column under Group Variable 1. Run displays the comparison in the Output window, where results can be viewed, edited, saved or printed. The built-in example uses the Mammals dataset, available through File > Open Example Data.
