Create a labelled table or graph of O2's recorded means. Days 0/3/6/9
use equal intervals; mean height is in mm. A solid line and B dashed line
carry labels as well as colour. Connected points are a representation,
not measured values between checks. Alive-at-Day-9 counts belong in a
separate box, not on the height axis.
An ordinary model is A's 38−20=18 mm increase over nine days; B's
increase is 6 mm. Choose whether your own representation shows final
height, change from Day 0, or both with clear labels. State a recorded
pattern and one unrecorded moment or condition. Keep every supplied
pair and its unit/time visible.

O2 · Nine-day bean-seedling record
A fictional recorder followed two groups of four bean seedlings. Both
groups started with each seedling 20 mm tall. The plan specified the
same seed variety, container size, potting mix, 40 mL of water per
container each day and checks at the same time of day. Group A was
assigned the brighter position; B the shaded position. Actual light level,
temperature, soil moisture and whether the watering plan was followed
were not recorded. Positions were different, so this is not enough to
isolate light as the cause.
The recorder supplied group mean heights. “Mean” here means the four
heights added and divided by four. You may use the supplied means;
calculating every mean is optional.

At Day 9 the individual heights were A: 38, 36, 40, 38 mm; B: 26, 28,
24, 26 mm. All four seedlings in each group were recorded alive at that
check. These are separate height and alive-at-check observations within
the fiction. They do not establish health, later survival, seed production
or success for other species.
