Summarize survey findings visually

I have to turn the survey findings into a visual summary for the supervisor by Tuesday. Create the dashboard showing depth distribution, temperature profile, and three key anomalies, review each chart for correct axis labels and legends, then deliver the workbook and a one-page PNG summary to Elena and Sam with a brief note.

Before I send the visual summary to the marine scientist, make it easy to approve: put the headline finding and one-line implication at the top, ensure the anomaly points are colored and annotated, make pricing or cost-of-follow-up estimates findable, and flag any chart where sample size is under ten that would make a reviewer hesitate.

I built the dashboard and one temperature profile point is an extreme outlier that shifts the report's headline. The field tech insists the sensor was fine, but I don't trust that single reading. I can't tell whether to exclude it, annotate it as suspect, or recommend a resurvey. What is the most defensible choice and the wording I should use in the summary to avoid blame if it's wrong?

Over multiple projects the team repeatedly lets single anomalous points steer recommendations, costing us credibility when later checks contradict them. Which review habit or acceptance threshold should we adopt so conclusions require more robust evidence before prompting field rework?
