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]
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]
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?
I'm looking for a fitness watch I can use for interval training. I don't need anything fancy, but I do want something that'll vibrate in place of beeping. Can anyone recommend something? [more inside]
Stuck at a fitness plateau. Not weight loss - fat loss. I'm about 5-8% (not exactly sure; I only have inexact measurement options) below where I want to be, which is the 10% mark. Help me get to my goal or as close as possible by the summer (and stay there)! [more inside]
Plug-in appliance timer filter: Does a one-minute timer exist? [more inside]
Digital compact camera needed, with ability to take shots at defined intervals, when left unattended (for time-lapse). [more inside]
Shopping for a heart rate monitor which includes an interval timer - this is the cheapest Timex ($78), this is cheapest Suunto ($115) and this is the cheapest Polar ($140). Does anyone have experience of any of these, or have other recommendations to offer? [more inside]
I'm in the (UK) market for a MiniDV camcorder. Ideally I want one with an interval rec feature so I can use it for making time lapse films. Does anyone know of a low-ish budget model that has this please?
Statistics filter: Interval or Ordinal data? [more inside]
IntervalSignalFilter: So, I have this archival recording of an interval signal from shortwave station WSHB, Cypress Creek, SC. Is it an excerpt from any particular song? [more inside]
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?" Say, hypothetically, an on-line film festival that runs all year but is refreshed with new films annually?
