I believe question 48 of 56 is wrong on the first section of the statistics flashcards...

Values - 42, 56, 74, 78, 79, 80, 82, 86, 88, 91, 91, 97


There are 12 values, which means the median would be the average of the 2 middle values - 81

The first quartile would then be the average of the 2 middle values in the first half - or 76.

IC answer - 80 for median, and then 74 for Q1.

if you look at the graphic, the 2 sides of the values are uneven.

Am I right?

Looks like your correct and the card is wrong. That is unless this is some funny type of stastics I have never studied. Math was never my best subject but this is pretty simple.
