Hello. Will you please take my rocketry survey for my statistics class. Thank you in advance for your time.

I have a Masters in Ops Research. What kind of study are you doing? Asking people if they have an interest in rockets on a rocketry forum doesn't bode well for randomized survey taking. Just sayin...

Apologies, this is for a Statistics course in a graduate school MBA program, and I was assigned a multiple linear regression analysis project. I felt like I might as well tie in my love of rocketry to the assignment. Thank you for your time in completing it, I appreciate it.

I've got ~25 years in custom market research and I would agree that sampling methods may be questionable if presented as "General Population" sample.
However this survey seems tailored enough to be a targeted sample, which is acceptable as long as you define the methodology of sample gathering/outreach.
I understand the difference between a random and targeted sample. I was actually asking a leading question to see if the OP would tell us a little bit about the survey. But telling us the purpose of the survey could skew the results. Always a tough decision as to what to ask and exactly how to ask it to prevent bias. Then again, the OP may simply be gathering data for the multiple linear regression analysis and doesn't care about accuracy or bias.
In one of my graduate statistics classes the professor showed us how to calculate the reliability of a system. He gave us the expected reliability of each of the components in the system and which items were in series and which were in parallel. Then he calculated the reliability of the system and the probability of a successful outcome. The system? The electric chair. He was a bit odd.
Want a debate? Ask a model rocketeer to do something and set back while the fun ensues.

Lately? Not at all.I've never had any trouble with the way I pack my chutes. How do you do it?
