What is Data Analytics with Python?
Data Analytics with Python is a fun-filled whirlwind tour of 30 hrs, covering everything you need to know to fall in love with the most sought-after skill of the 21st century. This course includes examples of analytics in a wide variety of industries, and we hope that students will learn how you can use analytics in their careers and life. One of the most important aspects of this course is that you, the student, are getting hands-on experience creating analytics models we, the course team, urge you to participate in the discussion forums and to use all the tools available to you while you are in the course
CRITERIA TO GET A CERTIFICATE
Average assignment score = 25% of the average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100
Final score = Average assignment score + Exam score
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF THE AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Q2. The formula for dissimilarity computation between two objects for categorical variables is –
Here p is a categorical variable and m denotes the number of matches.
- D(i,j) = p-m / p
- D(i,j) = p-m / m
- D(i,j) = m-p / p
- D(i,j) = m-p / m
Answer: a
Q3. Select the correct option for a data set with 7 objects and an interval-scaled variable ‘f’ we have the following measurements: f = (1, 2, 3, 4, 5, 8, 50) containing one outlying value.
- Std deviation (std_f) and mean absolute deviation (s_f) are equally affected
- Mean absolute deviation (s_f) is more affected by the outlier
- Std deviation (std_f) is more affected by the outlier
- None of these
Answer: c
Q4. Which of the following is true for K-means clustering?
- It comes under the partitioning method
- The number of clusters is predefined for this method
- Cluster similarity is measure in regard to the mean value of the objects in a cluster
- All of the above
Answer: d
Q5. Which of the following can act as possible termination conditions in K-Means?
- For a fixed number of iterations.
- Assignment of observations to clusters does not change between iterations. Except for cases with a bad local minimum.
- Centroids do not change between successive iterations.
- Terminate when Residual Sum of Squares (RSS) falls below a threshold.
- 1,3 and 4
- 1,2,3 and 4
- 2 and 3
- None of these
Answer: b
