A dataset containing morphine tolerance measurements from five experimental treatment groups. The data consist of tolerance values recorded for eight experimental units in each group, resulting in a balanced one-way design with 40 observations.
Format
A data frame with 40 rows and 2 columns:
- tolerance
A numeric variable containing the morphine tolerance measurement.
- grp
A factor identifying the experimental treatment group with five levels:
"MS","MM","SS","SM", and"McM".
Details
The treatment groups are coded as:
- MS
Morphine followed by saline.
- MM
Morphine followed by morphine.
- SS
Saline followed by saline.
- SM
Saline followed by morphine.
- McM
Morphine followed by challenge morphine.
The dataset represents a balanced one-way experimental design with five independent groups and eight observations per group. It is suitable for demonstrating one-way ANOVA, nonparametric alternatives, homogeneity of variance tests, post hoc comparisons, and effect size estimation.
