Method & conditions

One measurement per animal at day 14. Independent observations and approximately normal outcomes assumed. Welch inference is approximate.

What this does not establish

Measurement accuracy, independence, or a causal treatment effect. All 20 supplied animals are included; no exclusions.

The corrected group agrees with the supplied source row. The same value appears in the figure and contributes to the Control mean.

Calculation basis

20 observations. One comparison.

Welch t = −5.85; df = 17.817. The interval uses the same group direction as the reported difference. Values are rounded for display.

Computed illustrative values, not an issued SciGround verification record.

Declared, not verified

Research assumptions stay visible.

Agreement with a supplied record does not prove true animal identity, accurate measurements, random assignment, or absence of cage effects.

What changed?

M17 was assigned to Treatment in the earlier analysis input. The supplied source records place it in Control. The correction changes its group, while retaining its 26.2 g measurement and all 20 animals.

Both versions remain distinguishable. A prior result is not automatically evidence for corrected data. This example does not establish that the comparison was specified before data collection.
