So I've got this project I'm doing in statistics dealing with election results.
Basically I must determine whether winning with over 55% of the votes in presidential elections should be considered a "landslide".
I've got the percentage of votes the winners attained in the past 13 presidential elections.
I see two ways of analyzing this:
Consider the data binomial, where p=1 if a presidential candidate won with 55% of the votes or more; thus k would represent the number of candidates that won with more than 55% of the votes.
Or I consider the data normal, taking a sample mean of the percentage of votes the winner has.
I'm not very sharp when it comes to stastistics, so I'm a bit confused on which route to take.
Any help is much appreciated!
