Slovin's formula. NEED HELP!

[sunja90]

---

I know how the formula works. But I'm conducting a research study (thesis) and am confused as how to use it during sampling different populations.

For example, I am going to survey three different schools with the year level and gender as a variable. These are not the real data of my research, just random number examples.

SCHOOL 1 POPULATION
Freshmen - 98
Sophomore 100
Junior - 200
Senior -34


SCHOOL 2 POPULATION
Freshmen - 35
Sophomore 87
Junior - 100
Senior -341


SCHOOL 3 POPULATION
Freshmen - 124
Sophomore - 200
Junior - 166
Senior - 78

I'm pretty sure you don't just use the formula right away. I remember we used percentages and stuff, but I forgot how the exact steps worked. After which, you're supposed to get a number you can use in identifying which students to sample. (stratified sampling. e.g. you get 9 and therefore every 9th student will be interviewed)

Please help, I don't want to screw up during defense panel because of my sampling.

TS wla kay faculty adviser sa imo thesis? This would be a good time to ask his/her help/advice/lecture on that matter.

Bai TS, ayaw na lang pagsampling, take 1 or 2 sections each year level per school. Dili pa ka maglisud sa imo data gathering ana kaysa magrandom sampling ka sa total population per school down to per year level kay pwede ra man nimo mabilin sa adviser sa section ang questioners(if mag-questioner ka).
