Features

Statcato has two main windows: Log, where outputs of computations are displayed; and Datasheet, which contains sheets of data values that can be edited and manipulated using various utilities provided.

Basic data operations include:

  • Sort, rank, standardize data
  • Generate patterned data (simple number sequence and arbitrary data sequence)
  • Generate random samples (e.g. binomial, uniform, integer, normal distributions)

Probability calculations (probability density, cumulative probability, inverse cumulative probability) are supported for the following distributions:

  • Continuous: Normal, Student's t, Chi-square, F, uniform
  • Discrete: Binomial, geometric, integer, Poisson

 

The following statistical computations are supported:

 

  • Descriptive statistics (e.g. mean, sum, standard deviation, coefficient of variation, quartiles, skewness, kurtosis, etc.)
  • Normality test (Ryan-Joiner)
  • Sample size determination for mean and proportion
  • Confidence intervals for one- and two-population mean, proportion, and variance
  • Hypothesis Tests for one- and two-population mean, proportion, and variance
  • Correlation and regression (two-variable linear and non-linear regression, multiple linear regression)
  • Multinomial experiments (Chi-square goodness-of-fit, contingency table, cross tabulation)
  • Analysis of variance (one-way and two-way ANOVA)
  • Nonparametrics (sign test, Wilcoxon signed rank and rank sum test, Kruskal-Wallis, rank correlation, runs test)

Statcato also provides a calculator and utilities for creating graphs, including bar chart, box plot, dot plot, histogram, normal quantile plot, pie chart, scatterplot, and stem plot.
