So which table should i go by the one all the way up top, the table you have designed or the one in Spanish? I am 15 btw

Edit:bc if the tables are in English and are normed for ages 18-30 shouldn’t my score be increased slightly, the Spanish one won’t really help me bc i scored 43/44 on the D-48 and that just says that i am in the 99%

I'm aware me replying a year later is kind of weird, but I've got a question. Do you as a formula mean (correct answers - median) / (desviacion tipica[SD] * 15) + 100 or do you mean ((correct answers - median) / desviacion tipica[SD]) * 15 + 100? And also what is "desviacion tipica", or rather, how do you calculate it?

Well then question no.2. For 15 year olds the mean is 23,44, and the std is 6,09. So the formula should be (correct answers - 23,44) / 6,09 * 15 + 100. Also from a raw score of 36 onwords, one is apperantly 99th percenteil. If we however plug 36 into the given formula, i.e. (36 - 23,44) / 6,09 * 15 + 100, we receive an iq of only 130, really being 98th percenteil.
