Mortality data for checkerboard analysis of bioprotectants

This repository contains an Excel dataset of binary mortality outcomes from a two-factor “checkerboard” bioassay testing combinations of two treatments labelled OA and PE across multiple concentration levels. The data are in long (tidy) format with one row per observation (a single well/treatment in a given replicate run), and include plate well position, treatment identity, replicate/run, week/block, and mortality status.Total observations: 1,072 rowsTreatments: 67 unique treatments, comprisingCombined (OA + PE): 49 mixtures (7 OA levels × 7 PE levels)Individual: 16 single-compound treatments (8 OA-only and 8 PE-only)Controls: 2 (“Water”, “Tween1%”)Replication: 16 replicate runs (each replicate includes all 67 treatments once; 16 observations per treatment)Temporal blocking: 3 weeks (Week 1: replicates 1–6; Week 2: 7–10; Week 3: 11–16)
