Question

Using the Bar chart and select: Show numerical values:



Now using the best variable values how much O2 was produced?
Temp 25
Light Intensity 45
CO2 Level 450
Light Wavelength 450

Input these variables into the gizmo
38.1
52.4
73.5
82.5

Answer 1

Do you want a single value or a summary of those four readings? If those four numbers (38.1, 52.4, 73.5, 82.5) are replicates of O2 produced at Temp 25, Light Intensity 45, CO2 450, Wavelength 450, then:

- Mean O2 produced = (38.1 + 52.4 + 73.5 + 82.5) / 4 = 61.6 (units as shown by the gizmo)
- Median = 63.0
- Range = 38.1 to 82.5
- Standard deviation ≈ 20.1 (sample sd)

If you wanted a different summary (e.g., just the highest reading or the single reading shown by the gizmo), tell me which and I’ll report that.
