129: Best Data Skills to Learn (And EXACTLY When to Learn Them)

Speaker: 00:00:00

It's easy to be intimidated by the

insane amount of data tools out there,

2

: 00:00:04

especially when you're starting from

scratch and so many different resources

3

: 00:00:08

tell you so many different tools to learn.

4

: 00:00:10

In fact, a recent survey shows that

there's over: 2000

5

: 00:00:14

that you could be learning or using.

6

: 00:00:16

But here's the truth.

7

: 00:00:18

You don't have time to learn 2000 tools.

8

: 00:00:20

Heck, you don't even have

time to learn 20 tools.

9

: 00:00:23

And luckily for you, you don't need to.

10

: 00:00:25

That begs the question, what tools

should you start out with if you're just

11

: 00:00:29

starting as an aspiring data analyst?

12

: 00:00:31

Well, if you're just starting out, you

definitely don't want to waste time.

13

: 00:00:34

That is like the number one thing.

14

: 00:00:36

So you don't want to waste time

learning skills that aren't useful.

15

: 00:00:39

You also want to get your foot

in the door as soon as possible

16

: 00:00:42

and land that first data job.

17

: 00:00:44

So this gives us two different levers

or two different variables to play with.

18

: 00:00:48

Number one, how popular a data tool is.

19

: 00:00:50

And number two, How

difficult a tool is to learn.

20

: 00:00:52

We want to start with the popular

and useful data programs that

21

: 00:00:56

are easy to learn as well.

22

: 00:00:57

You can sort of think of this like a

2D matrix with the x axis measuring

23

: 00:01:01

difficulty and the y axis measuring

how often a tool is required.

24

: 00:01:05

So it makes sense to start with

the quadrant where tools are

25

: 00:01:09

high in demand and easy to learn.

26

: 00:01:12

This is the lowest hanging fruit and the

place where most people should start.

27

: 00:01:15

But that still means that we

have to determine what skills

28

: 00:01:18

are required the most and which

ones are the easiest to learn.

29

: 00:01:21

Now, what skills are in demand the most?

30

: 00:01:23

It's a difficult question to know.

31

: 00:01:25

One way is to trust experts

in the field like Ivy League

32

: 00:01:28

legend Columbia University.

33

: 00:01:30

They're smart, right?

34

: 00:01:31

They're super trustworthy.

35

: 00:01:32

Ivy League, Columbia.

36

: 00:01:34

Uh, and if you go to their

website, you'll actually see that

37

: 00:01:36

they state that MATLAB is the.

38

: 00:01:39

Third most popular data tool that might

not mean anything to you right now,

39

: 00:01:43

but I'll show you in a few minutes

how you can actually prove data wise.

40

: 00:01:47

This isn't true at all.

41

: 00:01:48

That MATLAB isn't even in the top

10 of data skills to learn, or

42

: 00:01:52

even the top 25 for that matter.

43

: 00:01:54

As a data nerd, we should try to use data

when answering these types of questions.

44

: 00:01:58

It's actually a hard data to

get, unfortunately, but luckily

45

: 00:02:01

for us, my friend Luke Bruce.

46

: 00:02:03

Has already been doing it.

47

: 00:02:04

He created something called Data

Nerd Tech, which is web scraped

48

: 00:02:08

and analyzed, 2.5 million different

data, job listings, especially the

49

: 00:02:12

requirements, and then reports.

50

: 00:02:14

What percentage of job descriptions

mention skills as requirements?

51

: 00:02:18

The data is constantly being

updated, but as of the creation

52

: 00:02:21

of this video, here is the top 10.

53

: 00:02:23

sql, Excel, Python, Tableau, power

bi R, SaaS, PowerPoint, word, Azure.

54

: 00:02:32

But honestly, I think only skills that

are required over 10 percent of the

55

: 00:02:35

time should be the real focus points.

56

: 00:02:38

So that leaves us with the big six.

57

: 00:02:40

SQL at 47 percent Excel at

33% Python at 31%, Tableau at

58

: 00:02:48

24%, Power BI 20%, and R 17%.

59

: 00:02:52

These are what I call the big six,

and they're the six most important

60

: 00:02:55

things to learn when you're trying

to land your first data job.

61

: 00:02:58

It's also important to note that these

results are for all levels of data

62

: 00:03:01

analyst roles, both junior and senior.

63

: 00:03:03

Senior and intermediate.

64

: 00:03:05

So just for the junior roles, there

might be some slight differences.

65

: 00:03:08

Now we know which data skills

are important and required

66

: 00:03:11

often in job descriptions, but

which ones are easy to learn?

67

: 00:03:14

Of course, learning data skills is

a bit subjective, depending on your

68

: 00:03:18

previous experience and honestly, your

intelligence level, but there are some

69

: 00:03:22

universal guidelines when it comes

to the ease of learning data tools.

70

: 00:03:26

Like you're probably

already familiar with Excel.

71

: 00:03:29

Am I wrong?

72

: 00:03:29

You've used it before.

73

: 00:03:31

Like in school or at another job,

you've analyzed some sort of data at

74

: 00:03:35

some point in your life, probably in

Excel, whether it's school or work,

75

: 00:03:38

you've probably opened up Excel.

76

: 00:03:40

Correct me if I'm wrong, go in the

comments and tell me if I'm wrong, but

77

: 00:03:44

you're probably okay at Excel right now.

78

: 00:03:47

And that's awesome because Excel is really

used quite often in the data fields.

79

: 00:03:51

That's why I think Excel is one of

the things that you should start

80

: 00:03:54

with when you're starting your data

career journey is because it's easy.

81

: 00:03:58

It's one of the easiest things

that you can learn because

82

: 00:04:00

you're already familiar with it.

83

: 00:04:01

And to be honest, there's not

even that much more to add to it.

84

: 00:04:05

Of course, there's different techniques

and things that you can do in Excel,

85

: 00:04:08

but chances are you're already

familiar with 50 percent of it.

86

: 00:04:10

Next there's BI tools, BI standing

for business intelligence, and

87

: 00:04:14

honestly, they're like the, PowerPoint.

88

: 00:04:16

If you haven't used Power BI or

Tableau much, they can sound quite

89

: 00:04:20

intimidating, but don't let it be.

90

: 00:04:22

Both are pretty easy.

91

: 00:04:23

They're just drag and

drop analysis programs.

92

: 00:04:25

It honestly feels a lot like PowerPoint

where you click on something and

93

: 00:04:29

you drag it to different places.

94

: 00:04:30

And based on where you drag

it, different things happen.

95

: 00:04:32

It's all point and click drag and drop.

96

: 00:04:34

You'll be able to figure it out.

97

: 00:04:35

I promise.

98

: 00:04:36

SQL or SQL stands for

Structured Query Language.

99

: 00:04:39

And it is a language, so it is a

little bit harder to learn, but

100

: 00:04:43

there's not really all that much,

honestly, when you're first trying to

101

: 00:04:45

land your first day at a job, there's

probably about 20 different commands

102

: 00:04:49

that you should be using in SQL.

103

: 00:04:51

And so while it takes time to

learn those commands, there's

104

: 00:04:53

only really about 20 of them.

105

: 00:04:55

And it's not that bad when you contrast

that to another programming language like

106

: 00:04:59

Python or R and I won't sugarcoat it.

107

: 00:05:02

Learning to program is hard.

108

: 00:05:03

It's like a new language.

109

: 00:05:05

That's literally why they call

them programming languages.

110

: 00:05:08

And it takes time to even know

the terms to start to program.

111

: 00:05:12

Concepts like loops, functions, variables,

these are very difficult to comprehend

112

: 00:05:17

and they take a while to figure out.

113

: 00:05:19

When I was first learning loops, It did

not come easy and it took me a couple of

114

: 00:05:23

weeks, but once you figure those out, then

you can actually start learning Python

115

: 00:05:27

or R that's the problem with these two.

116

: 00:05:29

They're really in demand, but

they're quite difficult to learn.

117

: 00:05:32

Now, of course, there are easy data

programs that we could be learning out

118

: 00:05:35

there, some that are maybe even easier

than Excel or easier than Tableau,

119

: 00:05:39

but they're not part of the big six.

120

: 00:05:41

So we're going to ignore them.

121

: 00:05:42

So in my opinion, these are

the easiest data skills to

122

: 00:05:44

learn from easiest to hardest.

123

: 00:05:47

Number one, Excel, two, Tableau,

three, Power BI, four, SQL,

124

: 00:05:52

five, R, and six, Python.

125

: 00:05:54

Great!

126

: 00:05:55

So now we know the most

required data skills and we

127

: 00:05:58

know the easiest data skills.

128

: 00:05:59

So we can combine these two lists

together and create our ultimate list

129

: 00:06:03

or what I call the order of operations.

130

: 00:06:05

To learning data skills.

131

: 00:06:07

Now you might remember this idea of

order of operations from when you

132

: 00:06:11

were learning math in grade school.

133

: 00:06:13

It's a concept to determine the

sequence in which mathematical

134

: 00:06:16

operations should be executed.

135

: 00:06:18

Basically it's what you do

first in a math equation.

136

: 00:06:21

You may even remember PEMDAS,

or if I like to remember it,

137

: 00:06:24

please excuse my dear aunt Sally.

138

: 00:06:27

And this is kind of a

mnemonic to help you remember.

139

: 00:06:29

The correct mathematical

order of operations.

140

: 00:06:32

So let's break down this

mnemonic one by one.

141

: 00:06:35

The P, or please, this stands for

parentheses, which basically means

142

: 00:06:38

you should perform the calculations

inside of parentheses first.

143

: 00:06:41

Next, there's the E, or excuse, which

is calculating the powers and roots

144

: 00:06:45

inside of the mathematical equation.

145

: 00:06:47

Next, there's the M, or the D.

146

: 00:06:50

Which is the my and the dear, which is

saying that you should do multiplication

147

: 00:06:54

and division from left to right.

148

: 00:06:56

Next, next is the A and the S or

the Aunt Sally, which means that you

149

: 00:06:59

should be performing the addition and

subtraction also from left to right.

150

: 00:07:03

Please excuse my dear Aunt Sally.

151

: 00:07:05

It's an easy way to remember where to

start and in what order to proceed.

152

: 00:07:09

It's basically the top right quadrant

of the data skill matrix or the

153

: 00:07:13

section with the Easy to learn skills

with the most in demand skills.

154

: 00:07:18

So here is my official data learning

order of operations, or simply

155

: 00:07:22

said the data learning ladder.

156

: 00:07:24

It's number one to learn Excel.

157

: 00:07:26

Number two, learn Tableau.

158

: 00:07:28

Number three, move on to SQL.

159

: 00:07:31

And four, finally finish with Python.

160

: 00:07:33

We're starting with Excel because it

is by far the easiest to learn and the

161

: 00:07:37

second most popular tool out there.

162

: 00:07:39

Then we're moving to Tableau because

although less popular than SQL or Python,

163

: 00:07:43

it's much easier to learn them both.

164

: 00:07:45

Like I said, drag and drop, click.

165

: 00:07:47

It's easy.

166

: 00:07:47

Then move to the most popular data

tool, SQL, which is a little bit

167

: 00:07:51

harder to learn than Excel and

Tableau, but still not nearly as

168

: 00:07:54

hard as something like Python or R.

169

: 00:07:55

And then we're going

to finish with Python.

170

: 00:07:58

Now you might be wondering,

well what happened to R?

171

: 00:08:00

Or what happened to Power BI?

172

: 00:08:01

And honestly, Power BI and Tableau

are similar enough that if you

173

: 00:08:05

learn one, learning the other is

not going to take you very long.

174

: 00:08:09

You'll be able to figure it out and a

lot of the concepts are quite the same.

175

: 00:08:12

That's also true with Python and R.

176

: 00:08:14

They are somewhat similar.

177

: 00:08:16

Once you learn one of these

languages, learning the other

178

: 00:08:17

language won't be nearly as bad.

179

: 00:08:19

My suggestion is just to

learn one for right now and

180

: 00:08:22

then pick up the other later.

181

: 00:08:23

Excel, Tableau, SQL, Python.

182

: 00:08:26

This gives you the data learning ladder.

183

: 00:08:27

And to make it easier to remember,

I created a phrase or mnemonic

184

: 00:08:31

that you can repeat in your mind

to remind you that this is the

185

: 00:08:34

fastest way of landing a data job.

186

: 00:08:36

It is every turtle sprints past.

187

: 00:08:39

Excel, Tableau, Python.

188

: 00:08:41

Or if you wish for the more

thorough version with Power BI

189

: 00:08:44

and R included, it is every turtle

powerfully sprints past rapidly.

190

: 00:08:49

When you're not sure what step to

take next on your data journey,

191

: 00:08:52

simply refer to this ladder.

192

: 00:08:53

I hope this helps, and if this video

did help, I'm sure you're going to

193

: 00:08:57

find this video super helpful as well.
