You've used the perfect description. I used to teach College Algebra at a very large community college (20K students). Each class of 30 students had 5-6 RT students. A high percentage of them needed to take College Algebra (same thing that you took in high school, just compressed into 1 semester, instead of a full year) multiple times to pass it. I definitely acknowledge that a large number of people are "math-phobic" so that's a contributing factor.chunkyfrog wrote:The RT is ignorant...
I don't say this to demean RT's but to illustrate that RT's are likely to be no better at interpreting data than the average user. While I use a brick, my RT recently sent me an APAP machine to do a 2 week at home titration study. Even though I told her that the 1st week of use had a VERY high degree of problems, like leaks (my nasal pillows were worn out and needed replacing and it took me several days to determine the cause), her recommended pressure was the 90th percentile pressure, from the report on both weeks of data. Had she examined the 2nd week only, she would have concluded that the recommended pressure should be 1.5-2.0 CM lower. Given the fact that I'm using a brick and the recommended pressure SHOULD have been in the 4.0-4.5 range, that 1.5 CM is a HUGE difference. She also know that 5.5-6.0 CM of pressure is a level where I get severe aerophagia symptoms.
I don't consider my RT to be incompetent. She's simply doesn't have a degree of comfort with data, is forced to revert to the standard reports that come from her SW and is not able to dig deeper. Given what I know of the people that I taught, she's a typical RT.
