Question:
The data set contains one row for every person who filled the survey. We use person and student interchangeably.
- Job: 0 for those students without a job, 0.5 for those students with a part-time job, and 1 for those students with a full-time job
- Program: program of enrollment
- C-Regression: indicates whether the student knows (1) or doesn't know (0) a certain programming language or topic
- Classification: indicates the level of knowledge (1-5) on classification
- Clustering: indicates the level of knowledge (1-5) on clustering
- Bach_0to1: 1 if time elapsed from graduation is less than a year; 0 otherwise
- Bach_1to3: 1 if time elapsed from graduation is between one and three years; 0 otherwise
- Bach_3to5: 1 if time elapsed from graduation is between three and five years; 0 otherwise
- Bach_5Plus: 1 if time elapsed from graduation is more than five years; 0 otherwise
Question 1
- Find out the ratio of people that know at least one among Python and Java and their Classification knowledge has to be at least 2.
- Compute the standard deviation of the Clustering knowledge (function std), for people with ProgSkills of 3
Question 2
For the MBA program, how many people have a Programming Skill knowledge of less than 4?
Question 3
Return the rows of those people who know the most Languages
Question 4
Let us define the "data science experience" of a given person as the person's largest score among Regression, Classification, and Clustering. Compute the average data science experience among all MBA students.
