I am doing a statistics placement test based on the Berman text, which is a perfectly readable and reasonable introductory book. This "study guide" appears to have been generated by extracting isolated words, then collecting Internet definitions of these, and cutting and pasting these into a "book" sans editing, often using the same text multiple times. My favorite instance is the definition of "performance" (Berman treats performance management substantively as well as using it as an example); the study guide repeats three times an extended definition based on ballet and choral "performance"! Apparently whoever wrote this did not actually trouble to read Berman, which, you know, seems like a minimum for a study guide. The "performance" (and many similar) examples are so absurd that students won't usually be led astray, but other instances are off by less, but still off in misleading ways, making this a most unreliable guide. Of course I wasted my money, but I am in a kind of awe at the audacious level of bad faith involved in generating - "writing" would surely be too strong a word - a work of this nature and proffering it to the public.
