**To:** dr.rivera@research.org
**Subject:** Apology – data error in Q2 report

Dear Dr. Rivera,

Please accept my sincere apologies for the data error in the Q2 report I submitted last week. I understand that this mistake could have had serious consequences for the department’s decision-making, and I am deeply sorry for my lack of attention to detail.

After reviewing my work, I discovered that I mistakenly used last year’s baseline figures instead of the updated ones provided in the March memo. Specifically, I copied the wrong column from the source spreadsheet when compiling the final table on page 4. This was entirely my error, and I take full responsibility.

To correct the issue, I have already prepared an updated report with the correct figures, which is attached to this email. I have also highlighted all changes in yellow for your easy reference. To prevent this from happening again, I will create a standardized checklist for myself to verify all data sources before submitting any future report. Additionally, I will ask a colleague to review my work before I send it to you.

Thank you for your patience and understanding. I greatly value your guidance, and I will work hard to regain your trust.

Sincerely,
Tom Garcia
