Complete first source
Four bean seedlings in each group start at the same recorded height.
The fictional plan assigns different light positions: A assigned brighter
position; B assigned shaded position. It specifies the same seed
variety/stage, container size, other scheduled conditions and daily
check time. Actual light level, temperature, moisture and whether the
schedule was followed are not recorded. These are constructed teaching
observations, not an actual controlled trial, care prescription or
instruction to alter living things. Every supplied mean includes all four
initially labelled height records; no height is missing. The survival count
is separate.
Day after start | A mean height (mm) | B mean height (mm)
0 | 10 | 10
3 | 14 | 15
The next check is proposed for Day 6. Its outcome and alive counts
have not been supplied. No measurement of future conditions or
survival is available.
Your first job
1. Calculate each group's recorded mean height increase from Day 0 to
Day 3; include mm and three-day period. Name the condition the plan
assigns differently.
2. Make a reasoned prediction about the relative mean heights at Day
6, or explain why a precise ranking is uncertain. Cite the earlier record,
distinguish a prediction from a result and give one relevant uncertainty.
Do not invent a future value or alive count.

3. Pose an investigable next question and propose a fairer repeatable
paper plan: changed condition, measured height/alive-at-check data, at
least two controls, observation schedule and reference rule, one
relevant risk/permission or school-review point. No investigation is
required or approved by this page.
Read-aloud, calculator, AAC/sign, directed marks or exact-word
