How you report your analysis will depend on the needs of the specific stakeholder.

For example:

Your CMO/Marketing Director will want:

1. Timely analysis that meets his/her specific needs.  This may be real time metrics.  This may be weekly, monthly and quarterly analysis.
2. A high level of relevant detail (but still concise and succinct).
3. First sight/approval of the figures before anyone more senior sees them.
4. A demonstration of how testing is improving ROI
5. Metrics that will help the Marketing department to make better marketing decisions (that lead to better business performance).
6. Business performance metrics (ROI, profit, sales, revenue, cash flow, margin, shareholder value) to present to the Board. Plus reliable and accurate figures to back-up these metrics. 

Your CEO/Director/Board will want

1. Business performance metrics only (ROI, profit, sales, revenue, cash flow, margin, shareholder value).
2. A demonstration that Marketing and Sales are working together to improve as well as prove the ROI on the marketing budget.
3. A clear and concise rationale (with reliable and accurate figures) to back-up these metrics.
4. A quick and simple way to view changes/improvements in the figures, via for example, a dashboard.
