Can I please have some help?
For the following statement about a statistical survey, identify the following items (if possible). If you can’t tell,
then say so – this often happens when we hear or read about a survey.
A recent online poll conducted by an Australian newspaper of 1083 registered voters found
that 43% of the respondents believe it is likely that bushfires are linked to climate change
a) The possible population of interest
Registered voters
b) The population parameter
Proportion of registered voters who believe it’s likely that bushfires are linked to climate change
c) The sampling frame
Not stated in the question
d) The sample
1083 registered voters
e) The sampling method, including whether or not randomisation was employed
voluntary response sample
f) Who (if anyone) was left out of the study
People who didn’t participate in the study
g) Any potential sources of bias you can detect and any problems you see in generalising to the population of
interest
People are more likely to participate in the survey if they have a strong opinion towards either side. What source of bias would this be?
Can someone please tell me if my answers are correct?
