A teacher would like to estimate the percentage of her students who play chess.
Which method should the teacher use to select the sample?
use a computer to randomly select 30 student IDs from all her students.
select all students who are currently in the chess club.
select every other student in her classes until she has selected a total of 30 students.
use a computer to randomly select 30 student IDs from all students.
+981 Hello!
The teacher her should definitely use a computer to randomly select 30 student IDs from all
students because it is more random and we can have a more accurate and reliable data set.
She shouldn’t select the people in the chess club because they obviously all play chess.
Using a computer to just select students from just her students is not broad enough.
Selecting every other student also provides an inaccurate data set because it depends on who sits next to who.
I hope this helps.
