Wink Has anyone taken the LPIC 1 exam and passed???


Hi ,
I am planning on sitting my LPIC 1 exam very soon, and so I had a look at the FAQs on the LPI.org.
They say the minimum pass score is 500, and average is 480 does this mean more people fail than pass?

I could be reading it wrong, but wanted to know if any here has passed recently?

Not necessarily. Average is not median. If a few people only score 20 then it drags the average score down. But it doesn't mean half the people got less than 500.

Median is a legitimate average. It all depends on how the figure was calculated.

The averages that I can think of off the top of my head are
  • Arithmetic Mean: The sum of the data set over the number of items in the data set (This is the most commonly used average)
  • Geometric mean: multiply the each item in data set and take it to root of the data set.
  • Harmonic mean: I don't really understand this but I know it is used in situations where you have rapidly increasing data set e.g. Average mpg
  • Mode/Modal: Is simply the most common value in the data set
  • Median: The vale of the item in the data set that has an index of half the total number of items in the data set

according to this link http://www.mail-archive.com/lpi-disc.../msg00695.html 500 is the median so half the people pass and half the people fail.

I would guess (but it is only a guess) that 480 is the [arithmetic]mean average and that a few low scores have dragged this down. This is impossible to say without looking at the dataset or at least having more information (such as which type of average and standard deviations).
