What are you trying to do?

Data I already have in agriculture and food science.

Your path

01

Create a study to hold it

A study is the container. You are not obliged to collect anything through ZStat.

02

Import the file

CSV for now, on the Data page. Leading zeros survive, and a column that is mostly numeric with a few words stays text rather than becoming numbers with holes in it.

03

Find out what you should be running

The guide for your field names the question in your own words and the procedure that answers it.

04

Analyse

Every result is stored with the digest of the data behind it, so you can prove later which version produced which figure.

What people in your field ask

In agriculture and food sciencethe full guide

Block the field - randomise treatments to plots - analyse at the plot level - separate the means.

  • Which variety or treatment yielded best?one way anova
  • Two factors at once - variety and fertiliser?factorial anova
  • My field slopes. Does that ruin the trial?factorial anova
  • Does the treatment relate to a continuous measure?correlation matrix
  • How long does the produce keep?kaplan meier

Watch for: Treating fifty plants from one plot as fifty observations. Randomisation was applied to plots, so the plot is the experimental unit and counting plants inflates n dramatically.
