Hi! Please use this contact form to contact me about website issues or other business matters.

If you have a statistics question, please post it in the comments section of an article that relates to your question. That way, I can answer your question, and other readers can benefit from seeing the answer. If you use this contact form to send me a statistics question, it won’t be answered. Yes, this applies to you!

When you post a comment on an article, it might take a day or two for the comment to appear on the website. I approve all comments to prevent junk and commercial type comments from appearing. It might also take several days for me to reply. Please be patient! I try to answer all questions, but the response time depends on my work load, holidays, travel schedule, etc.

Thank you for reading and commenting! –Jim
