# Sleep Studies

Using Absolutely Horrible Data.

sleep-studies-raw-data.txt

It's been well over a year since I collected this data. Sort of ironically, a loved one was talking about procrastination and this project rapidly came to mind, as I've been sitting on it (like) forever. But I suddenly found the will right after our conversation and pounded out a graph. That little thing of beauty (as I will be kind to myself, even if you will not) took me 1-2 hours. And this was after I'd already prepared the raw data and generated the following preliminary analysis.

### Sleep Studies Summary

``` DATA POINTS: 46 HOURS IN STUDY: 559.00 DAYS: 23.29 TOTAL PRE-SLEEP FUZZ: 7.30 TOTAL POST-SLEEP FUZZ: 13.63 TOTAL SLEEP: 199.15 Hours AVERAGE SLEEP: 8.55 Hours ```

Please see the raw data (a link is available at the top of the page) for further elaboration. But then, the only item that should be confusing is the `FUZZ` (as shown in gray in the graph above). Well, that's what I was calling that laying around in bed time, when one is not quite asleep, but trying to be so. It's not an accurate reading in the least, as I often lay awake in the middle of the night for 1-2 hours. So, like, I know the data is horrible.

I determined the Average Sleep (per day) by dividing the Total Sleep by the number of Days. But trying to determine how much I slept in a typical night was more troublesome, because I had to back out naps and those times when I was awake in the middle of the night.

To try and figure this out, I eliminated shorter spans of sleep. For instance, if I removed all periods of rest less than an hour in length, I wound up with 31 sleep periods, averaging 6.2215 hours each. And with that explanation, the other possible ways of interpreting the data should make more sense.

``` NO NAPS(<1)=(31): 6.2215 (ave length) NO NAPS(<2)=(26): 7.1673 (ave length) NO NAPS(<3)=(24): 7.5625 (ave length) NO NAPS(<4)=(23): 7.7384 (ave length) NO NAPS(<5)=(21): 8.0714 (ave length) ```

After this long, I can't say I care about the data, the analysis, or anything else related to this project in the least. Further, I question whether I learned anything... except for maybe how hard it is to manually collect sleep data on oneself and a future personal preference to collect data (any sort of data) in a full-on spreadsheet rather than as an iPhone note. But then, the iPhone is by my bedside, while a computer is not. And as such, I still find my iPhone (as opposed to my Android... for legacy reasons, I am sure) to be my preferred form of dynamic (so, like, in the wild and on the fly) mode of data entry.

Hey! Maybe (someday), I'll do a write-up on my movie watching habits. But as of this writing, that dataset is a total train wreck. And I'm even using a spreadsheet for that, so go figure.
