All Weeks Applied Data Science Capstone Coursera Quiz Answers
This capstone project course will give you a taste of what data scientists go through in real life when working with real datasets. You will assume the role of a Data Scientist working for a startup intending to compete with SpaceX, and in the process follow the Data Science methodology involving data collection, data wrangling, exploratory data analysis, data visualization, model development, model evaluation, and reporting your results to stakeholders.
This course is the final course in the IBM Data Science Professional Certificate as well as the Applied Data Science with Python Specialization. It is expected that you have completed all of the prior courses in the specialization/certificate before starting this one, as it requires the application of the knowledge and skills taught in those courses.
In this course, there will not be too much new learning, and instead, the focus will be on hands-on work to demonstrate what you have learned in the previous courses.

Exploratory Data Analysis using SQL Answers
Q1. Which of the following will retrieve the most recent date from the spacex table?
- SELECT MAXIMUM(Date) from SPACEXTBL
- SELECT HIGHEST(Date) from SPACEXTBL
- SELECT DATE FROM SPACEXTBL WHERE DATE=MAX(DATE)
- SELECT max(Date) from SPACEXTBL
Q2. Which of the following queries display the minimum payload mass?
- select payload_mass__kg_ from SPACEXTBL order by payload_mass__kg_ group by booster_version LIMIT 1
- select payload_mass__kg_ from SPACEXTBL order by payload_mass__kg_ desc LIMIT 1
- select min(payload_mass__kg_) from SPACEXTBL
- select payload_mass__kg_ from SPACEXTBL where payload_mass__kg_=(select max(payload_mass__kg_) from SPACEXTBL) LIMIT 1
Q3. You are writing a query that will give you the total payload_mass_kg carried by the booster versions. The mass should be stored in the mass column. You want the result column to be called “Total_Payload_Mass”. Which of the following SQL queries is correct?
- SELECT sum(PAYLOAD_MASS__KG_) as Total_Payload_Mass from SPACEXTBL
- SELECT sum(PAYLOAD_MASS__KG_) from SPACEXTBL
- SELECT count(PAYLOAD_MASS__KG_) as Total_Payload_Mass from SPACEXTBL
Q4. Which of the following query to display 5 records launched on Friday?
- SELECT * FROM SPACEXTBL where DAYNAME(DATE)=’Friday’ LIMIT 5

- None of the above
Q2. What are the total number of columns in the features dataframe after applying one hot encoding to columns Orbits, LaunchSite, LandingPad and Serial .
Here the features dataframe consists of the following columns FlightNumber’, ‘PayloadMass’, ‘Orbit’, ‘LaunchSite’, ‘Flights’, ‘GridFins’, ‘Reused’, ‘Legs’, ‘LandingPad’, ‘Block’, ‘ReusedCount’, ‘Serial’
Q3. The catplot code to show the scatterplot of FlightNumber vs LaunchSite with x as FlightNumber, and y to Launch Site and hue to ‘Class’ is
sns.catplot(y=”LaunchSite”,x=”FlightNumber”,hue=”Class”, data=df, aspect = 1,kind=’cat’)
sns.catplot(y=”LaunchSite”,x=”FlightNumber”,hue=”Class”, data=df, aspect = 1)
sns.catplot(y=”LaunchSite”,x=”FlightNumber”,hue=”Class”, data=df, aspect = 1,kind=’scatter’)
sns.catplot(y=”LaunchSite”,x=”FlightNumber”,hue=”Class”, col=”Class”, data=df, aspect = 1)
