How to sort posts by highest rated

First off I’d like to commend this plugin. It’s really the best I’ve used on my site
I’d like to sort my posts by highest rated on the front page. I saw that someone already raised an issue like this on the group and a code was provided. I tried it and it worked but there’s still a modification I’m in need of.
For instance two posts have been each rated 5 stars and one of the posts has a high number of people voting than the other, I’d like the post with the higher visitor votes to precede the other.

Below is the code that worked for me

`add_filter(‘posts_join_paged’,’yasr_join_paged’);
add_filter(‘posts_where’, ‘yasr_where’);
add_filter(‘posts_groupby’, ‘yasr_groupby’);
add_filter(‘posts_orderby’, ‘yasr_posts_orderby’);

function yasr_join_paged($join_paged_statement) {
if(is_home() && is_main_query()) {
global $wpdb;
return “, {$wpdb->prefix}yasr_log AS YL”;
}
return $join_paged_statement;
}

function yasr_where($where) {
if(is_home() && is_main_query()) {
global $wpdb;
return ” AND YL.post_id = {$wpdb->prefix}posts.ID”;
}
return $where;
}

function yasr_groupby($groupby) {
if(is_home() && is_main_query()) {
global $wpdb;
return ” YL.post_id, {$wpdb->prefix}posts.ID”;
}
return $groupby;
}

function yasr_posts_orderby($orderby_statement) {
if(is_home() && is_main_query()) {
return ” (ROUND(SUM(YL.vote) / COUNT(YL.post_id), 1)) DESC”;
}
return $orderby_statement;}

Thanks
