There are some parts of your answer which you could improve by using information you have already been given so I would suggest that you reread the advice you have already received and incorporate that before asking for further help & feedback.
In particular, you have been explicitly told what the sample is for this question and been given more sources of bias.
For stats the internet has a lot of resources and information so not having a textbook shouldn't be as big a hinderance as you might think
But for the above questions I've answered all parts of the question, and all I'm asking is for someone to verify if they're correct
Surely this is ok?
Guys I know I've asked this question before but I just want to make sure my answers are correct so I know i've understood it the correct way
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
1083 registered voters
d) The sample
43% of 1083
e) The sampling method, including whether or not randomisation was employed
voluntary response survey, randomization is NOT used
f) Who (if anyone) was left out of the study
people who didn't vote and people who didn't participate in the survey
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
Can you please tell me if my answers are correct? Be as harsh as you can
Thanks
