More Intuitive Navigation

Find related sheets easily

New family panel shows the family of sheets related to the current sheet, and chains of analyses are automatically indented

Easily navigate between multiple results tables

Analyses with multiple results tables now grouped into a single sheet with tabs for each result table; choose which tabs to show or hide

Improved Search

Search by sheets with highlights or notes of specified color


Now Featuring Eight Kinds of Data Tables

New: Multiple variables data table

Each row represents a different subject and each column is a different variable, allowing you to perform Multiple linear regression (including Poisson regression), extract subsets of data into other table types, or select and transform subsets of the data

New: Nested data table

  • Automatically generate volcano plot (difference vs. P value) from multiple t test analysis.
  • Nonparametric Mann-Whitney test, including confidence interval of difference of medians.
  • Kolmogorov-Smirnov test to compare two groups.
  • Wilcoxon test with confidence interval of median.
  • Perform many t tests at once, using False Discovery Rate (or Bonferroni multiple comparisons) to choose which comparisons are discoveries to study further.
