Ratings and Reviews

Good reference app but definitions are suspect.

pdthiem

I've found this app to be very useful and informative, but I am suspicious of it's accuracy. For example, the definition of precision is simply wrong. They define precision as;

"precision describes the degree to which individual measurements vary around a central value. Measurements with high precision are highly reproducible because repeated measurement will reliably give a similar result; "

I teach statistics and research methodology at a major California university and the above is actually for the concept of measurement reliability. "Precision" is actually defined as the degree to which one measurement differentiates one quantity from another. It's most easily thought of as how many decimal points a measurement can be made to. In other words, three decimals is more precise than one or two decimals. A measurement made to three places can differentiate two different quantities that a measurement made to two decimals cannot.

The moral of the story is that this is a useful reference source, but as with any other source, collaborating evidence should always be gotten to verify the source and/or the claims made by a reference. After all, that is how science works.

Seems good!

The negative reviews below are probably about old versions. This (possibly updated) version is pretty good. It's easy to use. It's good for looking something in particular up or just flipping through random terms and facts while sitting in a waiting room or in line. It might be nice if there were a back button so you could easily return to one you just looked at, and a quiz feature would be awesome!

Not High Quality👎

I was trying to find some vocabulary words for my science project to help me get some info, so I downloaded this app to help me. Well, I looked up just one of my vocabulary words, subsurface topography, and they didn't have it. So, I just typed in another vocab word, geological forces, and it didn't have that word either. Also, I notice some words in the app were misspelled too. Ps: I'm only in 6th grade so the vocab words might be kinda babyish to some of u ppl reading this review.
