Can you believe the time for New Year’s resolutions has come again? Maybe this year you can add to the traditional “I’ll eat healthily”, “I’ll stop smoking” and “I’ll hit the gym regularly” a new one: “I’ll look at statistics carefully”. You can start with these five simple tips.
- Reported averages might be meaningless
An arithmetic mean (sum of all values divided by the number of values), often reported as the average, in fact doesn’t say much about the average value.
Imagine you’re describing humans to extraterrestrial visitors. How many legs does an average person have? Slightly less than two.
For theatre addicts London is like a bar for alcoholics: a paradise and a hell at the same time. Since the beginning of my PhD I’ve spent a bit too much money and time on plays and musicals — more than I’d ever publicly admit. Meanwhile I’ve mastered the art of getting cheap tickets, so if you’re also a theatre lover on a student budget, read on! This article isn’t sponsored by any of the companies I mention (unfortunately).

You picked Imperial to become a scientist, engineer or a medical doctor. What do these careers have in common? You’ll need to write a lot: scientific papers, grant applications, lecture notes, popular science articles. Unfortunately, university curricula lack writing courses, so we end up with thousands of unreadable scientific papers. In my research I’ve chosen some mathematical methods just because the authors made them easy to understand; nobody has time or energy to look for interesting science hiding behind word clutter.
I’m a mathematician, not a writer, and my writing is far from perfect. Let me share five tips to improve your writing so that you can learn on my mistakes.
I’m definitely a social animal. While I need some “me time” once in a while, I tend to surround myself with people. This is why when I embarked on my first PhD journey, I wasn’t too thrilled to learn that I’d be travelling alone. That sounded so scary, I was afraid that something would go wrong or, in the best case scenario, I’d just feel lonely and miserable for a few days.
Since then I’ve been to so many conferences in various countries, often extended to a mini-vacation. Almost always, completely alone. And let me tell you, I learned to love it.
In my post about affording London prices I suggested bringing lunches to work, just to save money. No matter how busy I am, I do it most days, thanks to a collection of delicious and ridiculously quick recipes I collected (let me know if you’d like me to post them!). However, sometimes I treat myself to a lunch at Imperial. Where do I go?
At South Kensington campus we have a big choice of catering outlets that serve everything from sandwiches and salads to Japanese and Indian. About 11am they post the menu of the day, which helps to make an informed choice (and procrastinate from work for a few minutes).
And how to avoid it
However much you might try to think you make the best use of your time, I’m sure that there’s always some time during the day when you sit there not quite getting on with your work but pretending that you are. As a particularly keen procrastinator, especially when I find the work difficult, here are some of the ways I’ve managed to get through tough revision periods avoiding procrastination.
- Make a timetable with not more than 45 to 90 mins revision sessions at a time. Don’t just write down what subject or module you will be studying, include key details of what particular topic, or which past paper you will do in this time.
So how are you really feeling?
Thursday was Time to Talk Day 2018, a chance for us to speak openly about mental health, something that doesn’t happen as much as it should. There is a certain stigma associated with mental health, however when 1/4 people are affected by mental illness each year, it really is time to stamp out the sigma and talk about mental health. Following on from Paula’s post about what to do if you are worried about a friend’s mental health, I thought I would share some first hands tips of how to stay mentally healthy in a university environment and what to do if you feel that you are suffering in any way.
If you’re thinking about studying maths at Imperial, you might be wondering what kind of problems first year studenst are supposed to solve in the tutorials. Last term I was a graduate teaching assistant (GTA) for a course Probability and Statistics I. Let’s see an example of a question posed by the lecturer, prof. Emma McCoy.
Imagine that n people, including yourself and a friend, are seated at random in a row of n chairs. What is the probability that you sit next to your friend?
This problem is easier than you think, especially after following the lectures. I’ll explain how to tackle this problem here.
The MSc in Business analytics is an intense year of rigorous technical and quantitative training. It prepares students to solve business problems using a variety of statistical, operations research and machine learning techniques.
What you learn in class is usually just a small part of what you end up doing in group projects and homework. There is a huge amount of good resources you can use to learn new material or enhance your knowledge in a topic.
In this blog, I wanted to share the most useful sources I found in case you’re planning to pursue this program at Imperial.
Before you start the program: the basics
Statistics and probability
Start by revising your math skills in statistics and probability.
Let’s face it: doing a PhD isn’t always rainbows and unicorns. The process can be painful and annoying, and at some point you’re probably going to get completely stuck. If you’ve ever done any research, you definitely know what I’m talking about.
There’s something you need to do, usually some task that was supposed to be easy – a toy example, an almost standard code, a “quick” experiment to check your hypothesis. And here you are, spending long hours, days, weeks, even months, not even closer to solving your problem. You’ve tried everything, used all possible sources you could find, but this devil isn’t giving up.
