Transcripts
So in a way, as a data
analyst, I'm kind of like the most important person in the company.
Ever wondered what a data analyst does from day to day?
Hi, I'm Tom, and today I'm going to show you exactly that!
So what is data analytics and why is it one of the coolest jobs around?
The roles, around data, such as data analyst and data scientist
have been called in the past some of the "sexiest job titles in the 21st Century".
So what is a data analyst?
Well, there are different ways of answering that question, but at its core,
the data analyst needs to simultaneously be a storyteller,
a mathematician, a coder and a business consultant.
The data analyst uses code to pull data in from various different sources
and then uses code again to analyze those data sources to try and extract
meaning from those data sources
and then present those findings often in a visual way to the wider business.
More and more jobs these days are remote working,
and a data analyst basically can do their job from anywhere.
I personally find I like a hybrid model where I spend most of my time
working remotely, but I'm still able to come into a central place
where I can be face to face physically with my peers and colleagues.
So that's what I'm going to show you today.
So as a data analyst, I always like to start my day
with a good cup of coffee, so let's go and do that now.
- What's your morning ritual?
Great question.
My morning ritual varies between meditation and exercise.
I try and alternate days between meditation and exercise.
- What's your coffee choice?
Oh, what's my coffee choice?
My favorite coffee is a latte with oat milk
so now I've got my coffee.
I like to spend a few minutes doing prep work.
And so what does it mean by prep work?
Well, I like to spend a few minutes every morning meditating to get my mind
in the right space for the day ahead.
I like to check emails from the previous day
to make sure I've closed off any issues that are still outstanding.
And I also like to check news articles and emails to find out what's new
and interesting in the world of data
analytics and data science to motivate myself for the day ahead.
Now I'm done with my prep work.
I'd like to spend half an hour in team meetings.
So these meetings are super important for the data analyst's role,
because often data analysts like to work in team oriented structures,
which means a data analyst will work
with other members of the business or indeed other data analysts.
And these team meetings also provide a time oriented structure.
So data analysts often like to work in what's known as sprint cycles.
That means we like to spend one or two weeks
working on achieving a particular goal or set of goals.
And this morning team meeting is super important
so that the data analysts can align with the other team members
on what objectives are crucial in order to meet those goal or set of goals.
Typically, in that meeting,
the data analysts will look at a backlog of issues that currently exist,
and those issues are related to the objectives that need to be met
and the data analysts
will work with the other team members to prioritize those tasks and
to maybe remove ones that are no longer important or add new ones.
And with the body of tasks prioritized and chunked the data on this can
then make sure that that day is as goal oriented and productive as possible.
So now that we have our team meeting out of the way and we know what goals
we need to achieve,
we're going to spend a couple of hours focusing on data analytics.
In this data analytics section, we'll be preparing the tasks.
That means breaking the tasks
that we've already identified down into subcomponents.
We're going to be processing the data
that's in those tasks required to achieve those objectives,
and we're going to be testing and documenting our processes as we go.
So let's take a specific example.
Say as a data analyst, you're charged with trying to explain a discrepancy
between two different customer segments and you need to use data
in your business to do that.
So the first thing you're going to need to do is pull data from the sources.
What does that mean?
Well, you're going to need to use code like Sequel or maybe Python to pull data
from sources, such a SQL databases or maybe Excel spreadsheets
into a code repository like a Python IDE,
where you can do analysis on the data that you've just pulled.
So now that we have data from our original sources into our code
IDE, we can perform exploratory data analysis on that data.
We might be checking are there any data quality issues?
For example, we might start by looking to see is there any data missing.
We might also check the data quality of the data.
That is that
if we have a name column in our data source,
we might check to ensure that we have no numbers in that column.
Finally, now that we have data from our sources in our code IDE
and we performed exploratory data analysis to ensure that the data quality is high,
we're going to try and answer the business question
that we've been given using the data at our fingertips.
We can go ahead and close this question off as having been solved.
Now, all that's left for us to do is test and document the process.
We have the business question answered.
We need to make sure that it's answerable every time.
So we create a series of tests which ensure that the data quality
is maintained every time we pull data from its original sources.
And we need to document the process so we don't forget what we've done.
At every stage in the process
we document an explanation,
and this will also help us when we start to speak to stakeholders
to explain the reasons behind the actionable insights that we're taking.
Of course, we need to create data visualization,
and we need to create reports which allow us to communicate our findings
to the stakeholders.
But we've been spending a couple of hours on this already
I think it's probably time for lunch
Well, now I'm
back from lunch, and before I get to sleepy this afternoon,
I want to get the main focus of the afternoon out of the way,
and that's going to be producing the reports.
There are many ways a data analyst can communicate actionable insights from data,
but producing reports is one of the core ways that data analysts will do this.
There are normally two ways you're going to want to produce reports, either
interactive dashboards or static presentations.
If you're producing interactive dashboards,
you might be using a typical dashboarding tool like Tableau, Power BI or Looker.
These are powerful apps that allow you to summarize findings from various
different sources and use a variety of different visualization techniques.
These powerful apps allow the business to continue to analyze the data
as the underlying data sources change, and so they're integral part
of any business requirement.
But you may decide to produce a presentation instead.
These are naturally static, which means the underlying data doesn't change,
and so they tend to be used for one off presentations.
When you're trying to communicate
at the end of a project, your findings to the business.
Now you've decided on the format,
you just have to go ahead and produce the report.
And that basically involves
deciding which charts and what text you're going to include in your reports.
Different data sources require different visualization techniques.
So make sure to make the right decision about which charts to build.
Just like a book with only pictures is boring,
and yet a book with only text and no pictures is less appealing.
So in our reports, we want to include a combination of charts as well as text.
This helps
the end business user to fully understand the message that you're trying to convey.
Well, let's move on to the important topic of code maintenance.
If you're a data analyst,
it's almost guaranteed you're going to need to know how to code.
And so
I like to spend the next period of time in my day working on code maintenance.
Well, obviously the first component is writing new code blocks.
I like to code in Python and as a data analyst,
I'll also find myself using a lot of Sequel,
but different companies will require different programing languages.
So don't be confused if you're asked to learn a new language
joining a new company.
If you're looking for a new job, don't forget to look at the job requirements.
They'll often
list the code language that they work in or that they require you to work in.
But my personal tip - don't be put off if you don't already know this code
language.
Learning a code language is kind of like learning a foreign language -
the more you know, the easier it is to learn new ones.
And people will be impressed
if you can already solve problems in your existing code language.
So after having written some of my own code,
I like to move on to the peer review process.
This is where I, along with the other data analysts in the company,
like to work together to check each other's code.
This is an important part of being a programmer
because you're not infallible.
And so having a second pair of eyes checking over your work
not only helps you to spot mistakes, but also helps you to become a better data
analyst in the long term.
Being a good data analyst also involves writing
lots of tests, but don't worry, they're not as boring as they sound.
Writing tests means writing little controls into your code
to help you to check,
not only that, your data quality is maintained over time,
but also that your code quality is maintained over time.
So that bugs don't get introduced into your code base
and so that data quality issues don't get introduced into your data sources.
Finally, good data analyst has to use version control in their work.
This means using platforms like Git or GitHub so that your business logic,
your data quality and your code quality can all be maintained.
And if you make a mistake and write a bug into your code,
you can always roll back to a previous version.
Hey, we've spent quite a lot of time working by ourselves with other data
related people.
Now let's try and focus a little bit on the wider business.
And for that we're going to set up some stakeholder
meetings. Stakeholder meetings aren't a consistent part of your day.
There are some weeks
where you'll find yourself having meetings every day,
and there are some weeks where you get to work on your code or your data
all by yourself for the whole week.
In fact, stakeholder meetings are pretty atypical.
No two stakeholder meetings tend to be the same,
but they do share some general characteristics.
Obviously, your communicating, your findings or your current work
to a wider part of the business
and this can range from meeting with people in the product team,
meeting with the senior management, meeting with finance,
or even meeting with other data members of staff. In these meetings
it's important to have a strong sense of what message you'd like to communicate.
It's also important to be honest with the business.
No one's expecting you to be perfect, and you'll find problems
that you encounter along the way.
So be sure to be honest and transparent with the business.
Finally, the role of a data analyst in the company is to help the business
to make data driven decisions.
So be sure to use the data that you've worked on and the reports
that you've created to make actionable insights and helpful suggestions about
which direction the business can move in OK, now I'm done with my meeting.
I'm going to head back and do some more work.
Well, we're done with stakeholder meetings for today at least.
So let's move on to the next phase of our day, which is documentation.
A good data analyst should always document their work as they're going along.
This helps you to remember what you've learned
and what you've forgotten
so that in the future, when you look back on your work,
not only you know what's been happening, but also the wider business knows
what's been happening. All of the insights that you've derived,
all of the lessons that you've learned and all of your findings can be shared
with the wider business and saved for posterity.
OK, it's 5:00.
It's not going to be the most productive hour of my day.
So instead of doing any hard core work,
I would like to close my day by doing a little bit of research.
It's super important for data analysts to stay abreast of the market of data
analytics, data science, engineering, because this market changes very fast.
There's a lot of new techniques being introduced all the time,
so we need to spend a good amount of time focusing on research.
So where do I go to find good research?
Well, from a variety of sources.
First things first.
Good data analyst needs to be strong in math.
So I will go
back over math over and over again just to help it stay fresh in my mind.
And I can use different mediums for that.
I read articles online.
I love looking at YouTube videos,
or I might try and solve some puzzles on an app on my phone.
Yeah, we're going to link all the resources
that I use in the description below.
Another part of being a good data analyst is checking out new code libraries.
So for example, I'm testing out a new product called Copilot
at the moment that helps me write code cleaner and faster.
Another important part of being a data analyst is meeting other data analysts,
so I like to carve out some time to go to meetups, to go to webinars,
meet other data analysts, and network with the wider community.
So that's a little glimpse into what the typical day of a data analyst
might look like.
Obviously, some days are more meeting heavy, some days are more code heavy, but
I hope this gives you a general insight into what a typical day might look like.
