Working with statistics in Hellín

Students of IES Izpisúa Belmonte (Hellín) are working in the survey

• They translated they survey into Spanish so that their  classmates can answer easily the questions.
• Since teachers have decided that the sample is 20% of students, we decided to do a stratified random sample (for class groups)
• We made a random selection (students learnt how to use the # key in their scientific calculators). For this selection they used the following data:

• GROUP	NUMBER STUDENTS	NUMBER STUDENTS IN SAMPLE
  4º A	17	3
  4ºB	26	5
  1ºBACH A	33	7
  1º BACH B	29	6
  2º BACH A	31	6
  2ºBACH B	31	6

• Once we have the sample,students answer the survey
