A glasshouse experiment was conducted to examine how different doses of a growth regulator affect plant height under controlled conditions. Six increasing doses (Dose) were each applied to four replicate plants, with each plant grown in a separate pot. The pots were arranged in a completely randomized design on a bench grid comprising four rows (Row) and six columns (Column). After six weeks, the height of each plant (in cm; Height) was measured. This setup enables analysis of the effect of growth regulator dose on plant height, while accounting for any potential spatial variation across the grid layout.

Arguments
Format
A data frame with 5 variables: Pot, Row, Column, Dose, Height.
Pot
Factor. Unique identifier for each pot (experimental unit).
Row
Factor. Row position of the pot in the grid layout on the bench.
Column
Factor. Column position of the pot in the grid layout on the bench.
Dose
Factor. Applied dose of the growth regulator.
Height
Numeric. Plant height (in centimeters) measured six weeks after treatment.
