Posted by ricardogm on 26th May 2013


You are going to solve statistic exercises with excel. I’m going to give you a tutorial and some exercises to solve. Please send me an excel document at the end of the class.

estadistica-excel.pdf (This is the tutorial)

stats.pdf. These are the exercises to solve. You have to do the calculations and create charts (pie charts, bar charts, etc). The histograms in excel are poorly implemented, in my opinion. Geogebra does a much better work. Follow  the instructions in this example:
