Data Scientist Role Play: Profiling and Analyzing the Yelp Dataset Coursera Worksheet
This is a 2-part assignment. In the first part, you are asked a series of questions that
will help you profile and understand the data just like a data scientist would. For this
first part of the assignment, you will be assessed both on the correctness of your
findings, as well as the code you used to arrive at your answer. You will be graded on
how easy your code is to read, so remember to use proper formatting and comments where
necessary.
In the second part of the assignment, you are asked to come up with your own inferences
and analysis of the data for a particular research question you want to answer. You will be
required to prepare the dataset for the analysis you choose to do. As with the first part,
you will be graded, in part, on how easy your code is to read, so use proper formatting
and comments to illustrate and communicate your intent as required.
For both parts of this assignment, use this "worksheet." It provides all the questions
you are being asked, and your job will be to transfer your answers and SQL coding where
indicated into this worksheet so that your peers can review your work. You should be able
to use any Text Editor (Windows Notepad, Apple TextEdit, Notepad ++, Sublime Text, etc.)
to copy and paste your answers. If you are going to use Word or some other page layout
application, just be careful to make sure your answers and code are lined appropriately.
In this case, you may want to save as a PDF to ensure your formatting remains intact
for you reviewer.
Part 1: Yelp Dataset Profiling and Understanding
1. Profile the data by finding the total number of records for each of the tables below:
SELECT COUNT(*)
FROM table
i. Attribute table = 10000
ii. Business table = 10000
iii. Category table = 10000
iv. Checkin table = 10000
v. elite_years table = 10000
vi. friend table = 10000
vii. hours table = 10000
viii. photo table = 10000
ix. review table = 10000
x. tip table = 10000
xi. user table = 10000
2. Find the total number of distinct records for each of the keys listed below:
SELECT COUNT(DISTINCT(key))
FROM table
i. Business = id: 10000
ii. Hours = business_id: 1562
iii. Category = business_id: 2643
iv. Attribute = business_id: 1115
v. Review = id:10000, business_id: 8090, user_id: 9581
vi. Checkin = business_id: 493
vii. Photo = id: 10000, business_id: 6493
viii. Tip = user_id: 537, business_id: 3979
ix. User = id: 10000
x. Friend = user_id: 11
xi. Elite_years = user_id: 2780
3. Are there any columns with null values in the Users table? Indicate "yes," or "no."
Answer: "no"

8. Does posing more reviews correlate with more fans?
Yes, but also the amount of time that they have been yelping. The longer they
have been yelping and the more reviews they give has a higher fan count.
Please explain your findings and interpretation of the results:
SELECT id,
name,
review_count,
fans,
yelping_since
FROM user

Please explain your findings and interpretation of the results:
Yes, but there does seem to be one major outlier, number three Harald. The
other users seem to have a correlation with more `useful` and `funny`
results in more fans, but also in conjunction with review_count and time
they have been yelping.
Part 2: Inferences and Analysis
1. Pick one city and category of your choice and group the businesses in that city
or category by their overall star rating. Compare the businesses with 2-3 stars to
the businesses with 4-5 stars and answer the following questions. Include your code.
i. Do the two groups you chose to analyze have a different distribution of hours?
The 4-5 star group seems to have shorter hours then the 2-3 star group.
Please note the query returned only three businesses so not a great
sample size.
ii. Do the two groups you chose to analyze have a different number of reviews?
Yes and no, one of the 4-5 star group has a lot more reviews but then the other
4-5 star group has close to the same number of reviews as the 2-3 star group
iii. Are you able to infer anything from the location data provided between these two
groups? Explain.
No, every business is in a different zip-code.
SQL code used for analysis:
SELECT B.name,
B.review_count,
H.hours,
postal_code,
CASE
WHEN hours LIKE "%monday%" THEN 1
WHEN hours LIKE "%tuesday%" THEN 2
WHEN hours LIKE "%wednesday%" THEN 3
WHEN hours LIKE "%thursday%" THEN 4
WHEN hours LIKE "%friday%" THEN 5
WHEN hours LIKE "%saturday%" THEN 6
WHEN hours LIKE "%sunday%" THEN 7
END AS ord,
CASE
WHEN B.stars BETWEEN 2 AND 3 THEN '2-3 stars'
WHEN B.stars BETWEEN 4 AND 5 THEN '4-5 stars'
END AS star_rating
FROM business B INNER JOIN hours H
ON B.id = H.business_id
INNER JOIN category C
ON C.business_id = B.id
WHERE (B.city == 'Las Vegas'
AND
C.category LIKE 'shopping')
AND
(B.stars BETWEEN 2 AND 3
OR
B.stars BETWEEN 4 AND 5)
GROUP BY stars,ord
ORDER BY ord,star_rating ASC
2. Group business based on the ones that are open and the ones that are closed. What
differences can you find between the ones that are still open and the ones that are
closed? List at least two differences and the SQL code you used to arrive at your
answer.
i. Difference 1:
The businesses that are open tend to have more reviews than ones that
are closed on average.
Open: AVG(review_count) = 31.757
Closed: AVG(review_count0 = 23.198
ii. Difference 2:
The average star rating is higher for businesses that are open than
businesses that are closed.
Open: AVG(stars) = 3.679
Closed: AVG(stars) = 3.520
SQL code used for analysis:
SELECT COUNT(DISTINCT(id)),
AVG(review_count),
SUM(review_count),
AVG(stars),
is_open
FROM business
GROUP BY is_open
3. For this last part of your analysis, you are going to choose the type of analysis you
want to conduct on the Yelp dataset and are going to prepare the data for analysis.
Ideas for analysis include: Parsing out keywords and business attributes for sentiment
analysis, clustering businesses to find commonalities or anomalies between them,
predicting the overall star rating for a business, predicting the number of fans a
user will have, and so on. These are just a few examples to get you started, so feel
free to be creative and come up with your own problem you want to solve. Provide
answers, in-line, to all of the following:
i. Indicate the type of analysis you chose to do:
Predicting whether a business will stay open or close. We wish not to explicitly
examine the text of the reviews, but this would be an interesting analysis.
ii. Write 1-2 brief paragraphs on the type of data you will need for your analysis
and why you chose that data:
To better help businesses understand the importance of different factors which
will help their business stay open. Some data that may be important; number of
reviews, star rating of business, hours open, and of course location location
location. We will gather the latitude and longitude as well as city, state,
postal_code, and address to make processing easier later on. Categories and
attributes will be used to better distinguish between different types of
businesses. `is_open` will determine which business is open and which business
have closed (not hours) but permanently.
iii. Output of your finished dataset:
