Help me explain nominal, ordinal, and interval data, and means and modes

I'm on a project that is collecting ordinal data through surveys - for instance 'How satisfied are you with product X on a scale of 1-10?' We are analyzing and producing charts etc. using the mean as the reporting unit. I think this is wrong, and we should be using the mode. So: What are accessible and authoritative sources that I can read up on and also point to that show why we should be using the mode and not the mean? [more inside]

My family owns a timeshare (yeah, I know) through Interval International. We haven't booked any travel through the timeshare in at least 8 years. I've been put in charge of figuring out how to use it, and I have no idea where to start. [more inside]

Recommendations for inexpensive still-image, auto-uploading webcam

My organization is starting a major construction project, anticipated to take about 4 years. We'll be using a Nikon D5300's interval capability to capture high-resolution, high-quality images for archival and documentation purposes. We would also like to be able to monitor the progress remotely over the internet by using a webcam or other camera (under $200) that can take good-quality still images and upload them automatically to our server (or email them) via WiFi. More specifics after the click. [more inside]

Statistics question when value of test statistic t...

I'm working on a problem for "Inferences about the difference between two population means for independent samples: sigma 1 & 2 unknown and unequal." The final value of "test statistic t" falls in the rejection region for 95% confidence interval, but falls in the nonrejection region for 99% confidence interval. Should I perform additional calculations before rejecting my null hypothesis?

Recommendations on a heart rate monitor?

Recommendations on a heart rate monitor? I'm 27 and I go to the gym four to five days a week with a ratio of about 80% weight training (3-4 days) and 20% cardio (1-2 days). I'd like to do more interval training to lower my percentage body fat and many of the online resources describe this in terms of heart rate. Not knowing a thing about heart rate monitors, I thought I'd ask here. [more inside]

Can something be both "annual" and "all year?"

Can something be both "annual" and "all year?" Say, hypothetically, an on-line film festival that runs all year but is refreshed with new films annually?
