We put in relation two questions of opinion:
I like going to the school 1 And I like what I learn to the school 2 Frequency File of data : Number of records: 343 The percentages are established with regard to lines. All the records were selected.

With regard to the sex. 3 We want to know if the supplied answers are different with regard to the sex.

First, there is a frequency distribution according to the sex
4 And for all the pupils. 5 Note that only records including valid answers are considered here. Frequency File of data : Number of records: 343 The percentages are established with regard to lines.

Following the frequency distributions, we present the value of the chi-square indicating the degree of link between both distributions (here and 7.257). 6 For the first distribution, the indication of probability is situated at 0.00 indicating that there is a strong difference between both distributions; by examining the distributions, we notice that it is the girls who seem most "like going to the school". For the second distribution, the difference is less significant (a margin of error about 10%). Frequency File of data : Number of records: 343 The percentages are established with regard to lines.

If several variables are chosen, a summary of chi-square is presented.
