Stats week-1 question 10, answer must be only A, B

[Aayushi Sharma]

Table that we see in IIT Madras portal don't have average rating as variable. But if we see video solutions, they used different table. I am attaching both the tables.

Since all students were only able to see the 'Ratings' column but not 'Average Ratings' column', so answer must be AB only.

Please find the attachments.

Hi,

Here rating of the bike is given e.g. 4.3, 4.8 etc. that means it is average rating.  The data in both the tables is same and hence rating and average rating both are same, just a different column names.

But that was their choice, if they called that column rating, then we will consider it as rating column only. Since there is no column named average rating, D should not be in answer.

[Aayushi Sharma]

Here average rating only mean that, we have to take the average of rating column for this given dataset and that will be constant for this given dataset, not a variable.
