Here’s how she did.
Data and methodsLike last year, I set up a Google Form where Rachel could type in the title, author, and number of pages in each book as she finished, as well as the date of completion. I also added a field for her to rate each of the books on a 5-point scale (more on that later).
Again, like last year, we tried to get her to type in the books as she finished them, but we had a perpetual pile of books by the media computer waiting to be recorded. Accordingly, the dates for each book are not entirely accurate. The day of the week is almost always wrong but the weeks are generally correct, so all the analysis is limited to a week or month level.
ResultsThe raw data and code are all available online if you want to follow along. You can also read this on GitHub for larger images.
Summary statisticsRachel read 56,482 pages of 222 books in 2015, considerably less than last year’s 72,041 pages and 382 books. (22% fewer pages and 42% fewer books). On average, each book was 254 pages long, which is considerably larger than last year (35% higher), meaning that she read longer books this year. The majority of books were between 150 and 400 pages, with some clusters around 150, 300, and 400 pages (perhaps because publishers aim for those lengths?). Like last year, the longest book she read was Harry Potter And The Order Of The Phoenix, which was 870 pages long.
Rachel read books by 84 different authors, but as with last year, Rachel was a fan of certain authors and would try to read whole series at a time—we regularly had to convince her that standalone books were okay too. In fact, 15 authors wrote half of all the books she read this year. While J. K. Rowling was her clear favorite last year, this year Rachel read books by Lemony Snicket (Series of Unfortunate Events, twice), Carolyn Keene (Nancy Drew), R. L. Stine (Goosebumps), and Cressida Cowell (How to Train Your Dragon), among others.
Last year I manually calculated the Lexile score for each book, but I didn’t have the time or energy to do that this year. Plus it didn’t really reveal that much. She’s reading hard books—she read The Fellowship of the Rings in May, for example. That’s good enough. This year I asked the girls to rate the books they read, based on a 5-point scale I borrowed/stole from Goodreads: 1 = I didn’t like it; 2 = It was okay; 3 = I liked it; 4 = I really liked it; 5 = It was amazing!. Rachel either wasn’t really good at rating books, or she really thought that 85% of the books she read were amazing. She only disliked one book: Mike Thaler’s The Halloween Party From The Black Lagoon.
Trends over timeLooking at how Rachel read throughout the year also shows some interesting patterns. The amount she read was not very stable—she only read 9 books in May (one was Fellowship of the Rings, which probably explains the slowdown), while reading around 30 in July, November, and December (July because of our huge road trip, December because of Christmas break, and November because… reasons?). On average she read around 18 books and around 4,700 pages each month, or 5 books and around 1,200 pages every week.
Weekly data gives a more granular look at these trends. Notably, there are a few weeks where Rachel didn’t read anything at all. Lord of the Rings killed pretty much all reading in May, and early fall was inexplicably hard on reading.
Though it seems that she read more during breaks from school, the difference between the average number of books and pages in weeks in school and on break is not statistically significant (books: t (22.47) = -1.01, p = 0.322; pages: t (19.81) = -1.32, p = 0.203).
It would be cool to see which days of the week she read the most, but like last year, we were all lazy and didn’t always put in the correct day. Oops.
In general, Rachel didn’t read longer books as the year progressed (contrary to her Harry Potter-fueled mid-summer bump last year)—book length remained relatively constant throughout the year and wasn’t really correlated with school breaks.
Finally, Rachel’s original goal was to read 400 books, but it was too ambitious and she was never on track to actually meet it (and she never got around to revising it). The figure below shows the cumulative number of books she read during year. The green reference line shows what she would have had to do to reach 400 books by the end of the year; the dotted grey line shows her average trend (one book every 1.64 days)
ConclusionSo, in 2015, Rachel read 222 books that, in general, were 254 pages long. According to Wolfram Alpha, it would take 71 days of silent reading to read all 56,482 pages (full 24-hour days; no breaks for eating or sleeping!). That means she spent almost 20% of her year reading. Crazy. We’re so impressed with all of this and proud of Rachel!
Who knows what she’ll try (and what we’ll track) next year.
Thank you for this!! We have started one for our kidos! :)ReplyDelete
