A psychologist investigated the effect of workspace environment on administrative accuracy. Participants completed a 10-minute text transcription task under one of two conditions: Condition A (working in a quiet individual pod) or Condition B (working in an open-plan communal area with ambient noise). The psychologist recorded the number of typographical errors (typos) made by each participant.
The results are summarised in Table 1 below.
| Condition A (Quiet individual pod) | Condition B (Open-plan communal area) | |
|---|---|---|
| Mean number of typos | 4.2 | 9.8 |
| Standard deviation | 1.15 | 3.82 |
