I need to locate the correct line of code to remove the title from this page

I am attempting to edit the code to remove the default title that appears on most WordPress templates. I went to loop-page.php and removed what I thought was the correct line and nothing happened.

<?php post_class(); ?>>
<?php if ( is_front_page() ) { ?>
<h2 class="entry-title"><?php the_title(); ?></h2>
<?php } else { ?>
<h1 class="entry-title"><?php the_title(); ?></h1>
<?php } ?>
