Question 13 - Is it confusing?

Module 4. Linear Models Wrap-up quiz
#1

I had the correct results (from slightly less than 80% to a little more than 85%).

My problem was that -for me- going from 80% to 85% is “to improve by 6,25%” (if we improve 80% by 6,25%, it results in 80%*1,625=85%).

As it was slightly more than 85%, I was improving by 6,5%, so I have (incorrectly) answered “it improves the statistical performance by 7.5%” even having the correct numbers.

Maybe is my fault (or my english ;-), but perhaps it can be rephrased to be more clear.

Thank you for the amazing course!

Indeed, your approach would not be incorrect when we provide the word “improvement” and some percentage. We did not think about it :slight_smile:

We could specify an “increase of the accuracy score of xx” instead of the current formulation.

It is fixed. See Q13 rate of increase for more details
