I think there is a mistake at 8:15 with the calculation of the expected repair costs, as the value for "no damage" should have been multiplied with 0 but the percentage itself got added to the other values.
Correctly it would be 0 * 25 + 0,5* 40 + ...

I don't understand why the tree map is the best chart in the last case. I think a bar chart would be more clear, or a single stacked bar.

Hi, in the "Study" section, particularly under "analysis", the instructions said as follows: "Please round the final answer to two decimals", but on some answers you wrote down numbers without decimals, and on other with 3 decimals. How can I round them?

Hey ! So i bought the pack to train online, and I have an issue : my answers are not being recorded, making it complicated to do a review and compare to the correction. Am I doing something wrong ?

Hi. How do you change the number of decimals

Thank you very much. Can i kindly ask regarding choosing relevant data. I find it hard to figure out which is not relevant and i saw the picture of trash can in analysis phase does that mean we can choose all data and then just in the phase of analysis just delete unnecessary ones? And are there negative points for selecting all data and/or going back to investigative phase after we are already in the analysis phase? Thank you in advance

Thank you for this video! Very helpful!!
I have two questions: 1) In Case 3, when they asked about media, could we write =5 instead of >4?
2) In the same case, they asked about the mean and if there were more columns to the left of 4, would we say that the answer is <4?
