Reflection

Question	Answer
What did your data structure look like at first? Did this structure evolve over time? Why?	At first my data structure was a combination of arrays and hashes. It ended up with a combination of arrays and hashes, but with a slightly different structure. I started with a hash for trips but ended up making it an array of hashes instead. This changed because it made the data better to parse and easier to work with.
What was your strategy for going through the data structure and gathering information?	My strategy was going through the data and seeing which data points should be grouped together then going from there. I started with the large "grouping" then kept going smaller from there, which allowed me to think through my nesting structure as I went along.
What was an example of something that was necessary to store in a variable? Why was it necessary, useful, or helpful?	Something that was necessary to store in a variable was the driver id associated with the data. This was necessary because many of the questions required that the code outputted the rider with some sort of data. By having the driver id stored in a variable, it made it easier to output/associate data with eachother.
What kinds of iteration did you use? Did you use .map? If so, when? If not, why, or when would be a good opportunity to use it?	I mostly used .each and .map. I used .map when i wanted to print out all the data on separate lines while iterating through the initial hash of driver id.
Were some calculations easier than others? Why?	The first two calculations were easier than the last two. The ones where it was asking for which driver had the highest pay out or the highest average rating was harder because you had to compare data as opposed to just printing out the data in the first two questions.

Overall Feedback

Great work!

A couple things to note:
The rating math is being done with integer-math rather than decimal-math, causing it to be less precise than it could be. For example Driver 4 is given an average rating of 4, which seems to be rounding down from 4.67.
The later methods like highest_rated could benefit make use of earlier methods (average_rating, in this case) to limit the amount of repeated code.

But again, great work! Your data structure and methods are all readable :)

Great work!

A couple things to note:
It appears the rating math is being done with integer-math rather than decimal-math. For example Driver 4 is given an average rating of 4.0, which seems to be rounding down from 4.67.
The later methods like highest_rated could benefit make use of earlier methods (average_rating, in this case) to limit the amount of repeated code.

But again, great work! Your methods are all very readable as is the console output. :) Your total_earnings and average_rating methods are especially concise due to the clever use of sum!
