What are the benefits of using relative frequency calculations for user ratings in PHP?

When dealing with user ratings in PHP, using relative frequency calculations can provide a more accurate representation of the data by taking into account the frequency of each rating relative to the total number of ratings. This can help normalize the ratings and provide a more balanced view of user opinions. 

// Sample PHP code for calculating relative frequency of user ratings
$ratings = [5, 4, 3, 5, 2, 4, 5, 1, 3, 4]; // Sample user ratings
$rating_count = count($ratings); // Total number of ratings

// Calculate frequency of each rating
$rating_frequency = array_count_values($ratings);

// Calculate relative frequency of each rating
$relative_frequency = [];
foreach($rating_frequency as $rating => $frequency) {
    $relative_frequency[$rating] = $frequency / $rating_count;
}

// Output relative frequency of each rating
foreach($relative_frequency as $rating => $frequency) {
    echo "Rating $rating: $frequency\n";
}
