Because I'm a nerd

[kawaiikitsune]

I hate math and math hates me. I didn't even make it through the whole OP before my mind wandered off and I could have sworn I was reading a different language.

[ceejay]

I like math and I like this thread. Thanks for starting it, Ray!


(copying joy's format)...

I'm extremely regular. All my SD's are below 2.

Average ovulation: 14.5 +/- 1.6 days

Average luteal phase: 12.4 +/- 1.0 days

Average cycle length: 26.8 +/- 1.5 days

* Ovulation data for 11 cycles.
* LP data for 11 cycles.
* Cycle length data for 11 cycles.

SS here...

I have yet to ovulate on my own since going off of BCP last October. I *may* have ovulated the first cycle but I only had dotted cross hairs...

And my ovaries do what they want. And they don't like ovulating, period. #sneakyninjaovaries

I can't do math either. That's why I just copied off the smart kid, aka joy.

Whoa, I am crazy regular according to FF. Too bad that doesn't mean squat for getting pregnant. Le poo

Average ovulation: 14 SD 0.8

Average luteal phase: 11.8 SD 1

Average cycle length: 26 SD:1

I'm making us t-shirts, ok?! #sneakyninjaovaryclub #donthateuscusyouaintus

Average ovulation: 15.5 +/- 2 days

Average luteal phase: 11 +/- 1.6 days

Average cycle length: 26.5 +/- 1.9 days

* This data is for 8 cycles.


ETA:  The above seems pretty "regular", right?  What SD would make it "irregular"?

assuming normal distribution I'd say anything over 2 would be considered irregular by math standards since less than 5% of data is off in that area of the bell curve. Again, that is assuming a normal bell curve that the data probably does not follow lol. Also, average ovulation of 15.5 +/- 2 days would suggest you ovulate between 13 and 17 dpo generally. so your cycles can vary up to around 4 days cycle - cycle on average. I think I'm reading the data right - you can confirm?

ex. the following is my cycle length from cycle to cycle (each cycle compared to the one before it):

+10 days, -13 days, +7 days, +9 days, -9 days, +2 days, +2 days, - 6 days

so my cycle length is kind of all over the place. The sd takes into consideration the average of all the data and how much each cycle varies compared to that. 

So each of my cycles is approx 3.6 days off the overall average, on average. lol 

joy idk if I'm making sense - feel free to jump in lol or anyone else who's a stats whiz for that matter lol

uhhhh... this is where I admit that I never took a statistics class after 10th grade.

Yes, it's a glaring error in my education.

I had to take stats twice just to get a passing grade. I even have trouble saying the word statistics.

Alright lol I took a couple courses in university so I'm going to say in confident in my analysis of.....the analysis lol

[cheezee]

Nope! This is bringing back horrible memories! I had to take statistics online and I would just sit in front of my computer in tears every day.

[twocents6708]

This is bringing me anxiety from college stats class. It's the only C I ever received in college and I think the professor have me that out of kindness.

No math for me. My cycles are becoming more regular with the help of Metformin but I could O anywhere between CD16 and CD 25. If you don't count an anovulatory cycle after BCP, length of cycle is between 25-36 days. This is way better than cycles before the med.

I admire your nerdiness, Ray.

[cnf2013]

This thread is fascinating! I took a stats class in college, but even that was enough years ago that I cannot help you with understanding the break down. It was actually an epidemiology class with all the stats work shoved in at the end. I don't math.

Cycle length SD- 2.0
O day SD- 2.1
LP length SD- 0.6

I feel like I was super regular. All my cycles were pretty much 25 days on the dot except for a couple. I don't have a ton of charts to go off though, so it's not as accurate as I feel it could be if I had more data.

[nuggetrn]

This thread kind of makes me want to cry.

Because math.

Ugh.

[mosdub]

Stats was the only math class I felt like I understood most of the time.

[icaughtfire]

I don't math real good. I'm pretty regular. Until I'm not.

[daisy818]

My SDs are all pretty low, and frankly it was one wonky month that threw off my cycle length and O date averages (if I take it out of the stats then my SDs are all < 1):

Cycle Length: SD 1.3
O Date: SD 1.0
LP: SD 0.5

If only this consistency translated into getting pregnant!
