A5 · Growth-and-survival decision board

Choose a useful job

Choose a criterion for a fictional keeper. More recorded height increase conditionally favours Q: 16 mm versus P's 11 mm. More alive at Day 8 conditionally favours P: 6 of 6 versus 4 of 6. Keep the mean definition, original sample, period and unrecorded conditions beside the advice. Neither ranking supplies real care permission or cause.

Try the decision trail: criterion → relevant measure → conditional decision → limit → next question. Or repair “Q has four survivors, so it is four out of four”: the original six remain the denominator. A second ordinary brief requires increase at least 10 mm AND all four alive at Day 6. A +12 mm/3 of 4 fails survival; B +8 mm/4 of 4 fails increase. Neither meets both. Do not invent a combined A-growth/B-survival option.

O4 · Same-day height and survival notes

A fictional tray keeper recorded two trays on Day 0 and Day 8. Each tray began with six bean seedlings and mean height 20 mm. The different assigned daily water amounts were 20 mL for tray P and 50 mL for tray Q. The keeper does not supply temperature or soil-moisture readings.

Tray | Day 8 mean height | Alive at Day 8 | Initial seedlings
P | 31 mm | 6 | 6
Q | 36 mm | 4 | 6

P's mean increased 11 mm; Q's increased 16 mm. This table’s final means are calculated over all six originally labelled seedlings using their recorded heights, including those marked not alive; missing-height cells are not present. A living plant’s height and a stopped/still-standing stem can be different things. Do not recalculate a mean over only survivors and compare it with this one.

The record alone does not show that one water amount caused mortality. Nor does a larger mean increase settle a choice for someone prioritising the number alive. The supplied counts describe these twelve seedlings at this one eight-day check.

Complete diagram/workspace description

Separate tray panels: P start20mm,day8mean31mm,increase11mm,6of6alive. Q start20mm,day8mean36mm,increase16mm,4of6alive. Each panel has six equal count boxes with alive/notalive text (P6alive;Q4alive2notalive), illustrative count marks not individual identities. Mean includes all six recorded original heights. Criterion choices and own reason/limit trail stay blank.
