Version 2024.4

November 22, 2024

Controlled Environment

For studies held in a Controlled Environment (such as a growth chamber or greenhouse), document the environmental conditions for each day of the trial.

Step 1

Define the equipment (and the controlled environment itself) in the Equipment section of the Site Description.

Step 2

Link the equipment record to the daily entry on the Controlled Environment section.

Site Description report enhancements

Tables that do not fit on a single page wrap directly below the previous table section.

Added option to control borders of Site Description sections.

Option 2 pictured: Single separator line between Site Description sections

Version 2024.2

Equivalence Testing

Use Equivalence Tests to determine if treatments are effectively the same. The same AOV letters imply that treatments are "not significantly different" but this is not the same as "significantly the same" which is the goal of Equivalence Tests.

Step 1: Researcher defines how large of a difference is insignificant

This Limit creates an equivalence interval about the standard treatment for comparison.

Step 2: Hypothesis Test: the difference between treatments is outside the equivalence interval

Two one-sided tests determine if the difference is "outside the interval"

Define tests on Settings > Statistics tab

Limit can be entered as:

Percent of Standard
Absolute Value
Cohen's d
(a measure of effect size)

Analysis is performed when AOV option to Include equivalent tests is selected.

P-value for "smaller than lower limit" (1) and "larger than higher limit" are listed. Need both to be significant to conclude equivalence.

See Equivalence Tests for more examples from literature and real-life, as well as statistical calculations and theory.

'Required' Assessment Header field

Describe the necessity of an assessment or SE.

REQUIR – required rating which must be performed
ALTERN – alternative, a rating is required but allows a choice of at least 1 of assessments/SEs marked as ALTERN
OPTION – optional rating, but recommended to perform the rating when applicable
