Effect size in statistics

Imagine our population data is the red curve and our sample data is the blue and the post will help you make sense of it.

We’ve been talking statistics for the past few days and today we’re talking effect size. The short explanation is effect size is the difference between two conditions! The bigger the effect size, the easier it is to tell the two conditions apart, easy… right? There’s a lot that goes into determining effect size, after all it’s hard to know what your effect size is without having some prior knowledge about what you’re groups look like, so let’s go into some detail.

Great expectations

What did you want to be when you grew up? Sometimes the question ends in hilarity, a dinosaur, a unicorn, or maybe some other type of animal. Sometimes it leads to dreams of a sci-fi future, deep space traveller, Mars colonist, maybe a superhero. Whatever the answer is, they all have something in common. No one dreams of being average, but the average exists because so many people fall into it. Most of us have our dreams die as the reality of our existence becomes clear. I say fuck that, dream big until your last breath, why not?

A look ahead

With the weather trying to kill everyone, the pandemic trying to kill everyone, and just life in general I feel like things are moving…. slooooow. I have a weekly meeting with my main-PI who reminded me that I’m behind and while he agreed it was probably due in part to the pandemic, it’s time to try and catch up. There is a lot going externally and internally, but I’m hoping that by covering a few things here I will have a nice little list I can refer back on and keep me on track. That’s the idea anyway.

What is good outreach?

Yet another outreach event in the books! I have two more events this week and I believe that’s the last for my skype a scientist commitment. Since this term I was assigned classes practically all at once, I may re-volunteer to get a few extra classes in this term. Normally requests for my specific field don’t happen, but they’ve become more frequent, which is interesting to see because biomedical engineering, or my subset neuroengineering, isn’t a widely known field, but it is growing. All this recent outreach has gotten me thinking about what makes a good presentation, so let’s talk about it.

Outreach as a hobby

I reference this photo later in the post, but it’s my robot foot!

It feels like only yesterday I was fighting to stay alive and stay warm, but now like a bad dream it’s gone before it settled. Sure I’m still stiff from sleeping on the floor and the water isn’t on yet, but life has quickly thrown us back into “normal.” I don’t understand how people can shift so suddenly like the last week didn’t happen, but here we are, and here I am getting ready for another round of outreach.

Full speed ahead

Neither rain, nor sleat, nor pandemic, nor freezing to death stop us from moving forward. I think that’s how the PhD motto goes anyway. Since the past week we’ve been struggling to simply live, we’ve had the whole city sort of on pause. That pause has come to an end, there is no recovery period here, it’s straight back to work. That’s a feature of capitalism, not a bug and it isn’t limited to getting a PhD, but we’re definitely included in the back to work group.

Surviving catastrophe: A how to guide

Well what a crazy time to be alive, a time where everything is trying to kill us. Okay I acknowledge that nature is one ruthless force, but a lot of what has happened in the past few days has been almost completely due to human greed. Between the global warming causing this “once in a lifetime” storm — that is certainly not once in a lifetime — and power companies more concerned about profit than human lives, it’s been a trial. People, real people like you or I, but with far more money, are trying to kill us. Don’t give them the satisfaction.

I lived!

What a combo breaker, two years of dedication and daily blogging down the toilet because the government was trying extremely hard to kill me. I’m not mad, just disappointed, okay I’m very mad (in the government stuff, not my streak that’s not a big issue). Technically I’m not through the storm quite yet, the power could still go back out, but I have had power longer now than I have in the past few days. Long enough to write a quick update anyway.

Well… the US is frozen

It’s beginning to look a lot like Christmas… not in the fun way either. Here in the US we’re almost completely blanketed in freezing weather and in most cases, lots of snow. Which of course means power outages, rolling blackouts, and generally trying to prevent the state from letting me freeze to death. It’s a whole lot of fun, I highly recommend it. When the temperature drops like this I’m reminded of times in my life where I couldn’t find a warm place to stay and that makes me nervous for the people stuck outside right now.

On the stories we tell

It’s been a busy week, there was so much to do that I was worried it wasn’t going to all get done, but here we are! Things got done, mental health was prioritized, and I figure it’s a good time to talk about words. Or rather the stories they form, it’s a complex topic and this is really more for me than anything, a friendly reminder that I really enjoy writing. After all, while this blog is meant to help others, it’s also a message in a bottle to my future self, a reminder that I was really here and actually did the work. An ever growing time capsule of my thoughts if you will.

My scicomm video is done!!

I finally finished my video for the outreach project my main-PI tasked me with (this was the last post talking about it). There was a lot of time, effort, frustration, and I will admit, some not so kid appropriate language I was using during the editing process of the video. Mostly because I’m an idiot who had to find the most difficult way to do this project. Today we’ll cover what I did, how I hate myself enough to do it, and the end result. Let’s just say I’m not going to be a movie director or actor anytime soon…

The road to a PhD program

In hindsight this post should’ve happened a long time ago, like year one and day one of my 365 days of academia project. Things have… evolved in ways I didn’t understand when I started this, originally the project was simply going to be a notebook for my classes, then it turned into my journey as a whole, and even what I do in my spare time. Like anything we create it took on a life of its own and I’m reminded I should touch on the process to getting accepted into a PhD program.

Paper submission!

This morning I woke up to some good news! I got an email letting me know that the journal paper I’ve been working on has been submitted. It’s not the end, it’s only the beginning really. It needs to be reviewed before we know the outcome, but I’ve spent the past ten months or so writing this damned thing, so this is a huge moment for me.

The tightrope of mental health

My mental health is like walking on a tightrope, one slip and I’m done. Getting back up could take years for someone like me. The truth is, things are hard on the best of days. Getting out of bed, shaving, cutting my hair at regular intervals, things that would come easy to some require sheer force of will to accomplish. All the small choices through the day eat away at what little energy I have until I’m drained before breakfast. Yet here I am, pushing forward. It’s days like today remind me that for all the progress I’ve made, it’s still just a tightrope I walk.

Back to outreach

Just hanging out with the bots.

Today was the finish line, like it or not the R21 grant had to be finished. My Co-PI seems happy enough about the outcome, so we’ll have to wait and see what the result is, it could be several months before we know anything. It was a marathon of work, data process, experimenting, and now… nothing. I’m finally done so I can actually focus on other projects, which is the topic of the day!

R21 Deadline

Today is the FINAL day for me draft before we send the R21 proposal off for internal review. Technically I think we have all day tomorrow too, but I need to get this back to my Co-PI for review and his final edits before we can submit it. The good news is the scientific writer was very thorough with their edits and suggestions, the bad news is I told my Co-PI I would get it back to him tonight before realizing how much there was to do!

The zero factorial

Permutations and combinations and math, oh my!

Today I’m doing some stats homework and was reminded of an odd quark in math, the zero factorial. It’s not very intuitive and I absolutely love weird math, so I thought I would share the fun. I never said I was normal… Anyway today we’re going to go over why 0! (zero factorial) is so interesting!

A clear path!

The easy path to getting your PhD…

That was quick! I have an update regarding yesterday’s funding debacle already… it’s good news, but that’s all the hint you’re getting for now! Things are happening fast and frankly they need to I only have a few more days to finish the grant before its due for internal review and I don’t know how my Co-PI is feeling right now, but I’m stressed out!

Trouble on the horizon

I did not see this one coming… or maybe I did and just wanted to pretend it wasn’t going to be an issue. There’s been a difference of opinion to put it lightly. I received an email this morning from my main-PI asking if we could meet to discuss my funding options and he also casually mentioned that the R21 might not get submitted.

Scientific figure design

Well I’ve done it… sort of. I edited the grant for the semi-last time. Now we’ve got a working copy that reads the way we want it to read, so it’s off to the scientific writer to read over it and make sure it sounds good. You would think that means my work is done, but no. I need to do arguably the hardest part and create some of the figures we will use in the paper. Writing well takes practice, but making a good figure, well that’s art.

Not cool Robert Frost!

“Two roads diverged in a yellow wood…” starts Frost in a poem that most people are at least familiar with, but typically is misnamed. The poem is typically identified as, “The Road Less Traveled”. This makes sense because the poem talks about the thought process behind why he chose the road less traveled and that it was worth it. That’s not the name of the poem though.
