# A statistician's going rate and needs?

I'm finding myself in the comfortable position of being asked to run stats for people on their articles. I've been paid in three different ways:
• Authorship
• Money
• Combination Money and Authorship

As I do more of this work I have a few questions.

1. When receiving money for a project what is your rate? Is it per job or hourly (I find some jobs are hard to predict how much time some jobs will take and the client often asks for additional work)? I am US and the dollar is my only frame of reference. Since the US dollar is recognized world wide I would prefer the frame of reference around a dollar (though I can do the conversion if need be).
2. Do you usually work by verbal agreement or some sort of written agreement?
3. Do you charge the same for visualizations as for stats work (I'm becoming known for my visualizations around my department)?
4. What materials do you ask the client for (on my last job I ran stats on variables that were incorrect because I did not have a variable key to decode their meaning)?
5. What items do you give the client (summary write ups, program scripts, related articles etc.)?

PS Bryan and others looking to make side money, I'm finding this is a way to do this and be able to choose jobs you'd like while declining those you don't have an interest in.

Not that I really have experience in this area, but I do understand some of the environment.

1. The rate depends on the project and time commitments. Some people or assignments may be more aptly approached on a per-hour basis. For instance, tutoring is a good hourly paid job. But you could still turn it into a project paid job if you, say, have them pay for a whole semester's worth of tutoring with a commitment to deliver 3 sessions a week. See the difference? It depends on the assignment. In any case, project pricing is still fundamentally based on an hourly wage you expect to be paid and the time you expect to put in. So if you tutor for $20 an hour. You expect a weekly 3 hourly sessions to run$60. For a 16 week semester that's $960. However, you can give an obvious discount to, say, a$15 or \$10 hourly wage because you now have a financial commitment. That is the point behind bulk pay: you get cheaper for more quantity, and as a business entity, you get reliable income over that time frame. (Alternatively would be to give a percentage discount on the hourly fee when bulk purchases of a service are bought.)

2. Verbal is legally sufficient, but that doesn't mean you shouldn't cover your arse. Always have something in print. For instance, you could have a blanket waiver or something that outlines your service and either give it to them (their possession is acknowledgement of awareness) or have them sign it for even more assurance (keep a copy). It really depends on the level of professionalism you're going to have. If a friend is paying me under the table, so to speak, for training them at the gym, I'm probably not going to have them sign a release of liability form! On the other hand, when I was training, it was a mandatory part of my initial meeting to get paper work and assessments out of the way.

3. I don't know if I'd categorize them as different priced products. You're providing a service. They're paying for the service. That service comes with certain deliverables unique to the project. This goes back to 1. If visualizations take more work for you, then you're probably going to charge more for that work (your time is money, literally, and it takes more time to do them, so it costs more--the math don't lie!). With that said, you could always market your visualization techniques and offer it as a special service that costs more. Fundamentally, as I said, it goes back to your time, but the nice thing about visualization is that it's a tangible deliverable that has more 'punch' than, say, delivering a cleaned up data set or a report on some analysis. The distinction is really up to how you want to sell yourself.
