00:00:05,670 --> 00:00:11,580
Hello everyone and welcome to the lecture discussion on what is data science and this lecture will briefly
2
00:00:11,580 --> 00:00:17,610
be discussing three main topics we'll talk about the growing interest in data science is a field.
3
00:00:17,610 --> 00:00:23,100
The growing demand for data scientists in the job market as well as an overview definition of what is
4
00:00:23,100 --> 00:00:25,290
data science.
5
00:00:25,370 --> 00:00:30,930
A simple Google Trends search for the term data scientist reveals a recent explosion in popularity for
6
00:00:30,930 --> 00:00:33,710
people searching for the term data scientist.
7
00:00:33,720 --> 00:00:37,650
This is because data science can affect so many fields and domains.
8
00:00:37,650 --> 00:00:42,180
You may already be familiar of domains that work closely if data science such as machine translation
9
00:00:42,330 --> 00:00:45,970
speech recognition robotics search engines etc..
10
00:00:46,080 --> 00:00:52,980
However they do science can affect other fields such as biology health care humanities finance Medical
11
00:00:52,980 --> 00:00:59,010
Informatics business economics and so much more because data science is applicable to so many fields
12
00:00:59,010 --> 00:00:59,920
of study.
13
00:00:59,970 --> 00:01:05,310
The explosion of popularity and the ability to use data science has grown just in the past few years
14
00:01:05,450 --> 00:01:06,520
tremendously.
15
00:01:06,810 --> 00:01:12,450
Searching for job trends on indeed dotcom also reveals Eytan exploding demand for data scientists in
16
00:01:12,450 --> 00:01:13,640
the job market.
17
00:01:13,890 --> 00:01:20,190
Over the past four years there's been a 1600 percent growth in job postings for the term data scientist
18
00:01:20,190 --> 00:01:20,510
.
19
00:01:20,610 --> 00:01:25,920
In fact data scientists has been called the sexiest job of the 21st century by the Harvard Business
20
00:01:25,920 --> 00:01:33,450
Review McKinsey and Company project a global excess demand of 1.5 million new data scientists needed
21
00:01:33,450 --> 00:01:33,980
.
22
00:01:34,050 --> 00:01:37,420
This is going to lead to a huge skills gap that you can fill.
23
00:01:37,470 --> 00:01:42,900
Allowing data scientists the man very generous compensations for their new skill sets.
24
00:01:43,500 --> 00:01:48,720
The explosion of the popularity of data science can be attributed to many factors but there's four main
25
00:01:48,720 --> 00:01:50,220
driving factors.
26
00:01:50,220 --> 00:01:54,120
One is that there's more data being created than ever before.
27
00:01:54,210 --> 00:01:58,860
The second being large computing power is easily available.
28
00:01:58,860 --> 00:02:04,230
Things such as Amazon Web Services and Google's cloud computing platform have allowed us to have large
29
00:02:04,230 --> 00:02:06,870
computing power at our fingertips.
30
00:02:07,080 --> 00:02:12,870
The third being new programming tools tools such as the our programming language to help you quickly
31
00:02:12,960 --> 00:02:16,650
analyze data and perform statistical analysis on it.
32
00:02:16,650 --> 00:02:22,770
And finally this huge skills demand has led to generous compensation for data scientists meaning more
33
00:02:22,770 --> 00:02:28,500
and more people are willing to jump into the new field will learn a lot and demand those higher salaries
34
00:02:28,500 --> 00:02:30,270
.
35
00:02:30,270 --> 00:02:36,570
Now let's talk about a definition of data science we can think of data science as an intersection of
36
00:02:36,570 --> 00:02:42,960
fields the intersection of computer science math and statistics knowledge and then general domain knowledge
37
00:02:42,960 --> 00:02:43,280
.
38
00:02:43,320 --> 00:02:46,690
We can look at the intersection of just two of these fields.
39
00:02:46,830 --> 00:02:52,440
For instance the intersection of computer science and math and statistics leads the field of machine
40
00:02:52,440 --> 00:02:53,510
learning.
41
00:02:53,520 --> 00:02:58,230
You should note that machine learning is not the same thing as data science instead of machine learning
42
00:02:58,290 --> 00:03:01,170
is part of data science.
43
00:03:01,170 --> 00:03:06,090
If we were to cross computer science and general domain knowledge of a specific field you would get
44
00:03:06,090 --> 00:03:12,390
software development meaning use using computer science knowledge develop software very specific domain
45
00:03:13,130 --> 00:03:18,270
and then if you combine math and statistics with domain knowledge you'll get classic research such as
46
00:03:18,270 --> 00:03:21,580
research performed in social sciences in academia.
47
00:03:21,750 --> 00:03:27,270
It's the intersection of all three of these topics where you get data science as an outcome in this
48
00:03:27,270 --> 00:03:27,750
course.
49
00:03:27,770 --> 00:03:31,790
You'll learn how to use computer science programming with the R programming language.
50
00:03:31,950 --> 00:03:37,710
The math and statistical analysis available in our programming language and apply it to various domains
51
00:03:37,710 --> 00:03:42,650
of study in order to fully understand the full data science lifecycle.
52
00:03:43,010 --> 00:03:47,490
All right let's start learning all these new skills with the rest of the course.
53
00:03:47,490 --> 00:03:49,470
Thanks everyone and I'll see at the next lecture
