adding wp_footer() hook inside theme and then this code to add script to footer and worked fine for me
function slider_option()
{
$default=array(
'effect'=> 'random', // Specify sets like: 'fold,fade,sliceDown'
'slices'=> 15, // For slice animations
'boxCols'=> 8, // For box animations
'boxRows'=> 4, // For box animations
'animSpeed'=> 500, // Slide transition speed
'pauseTime'=> 3000, // How long each slide will show
'startSlide'=> 0, // Set starting Slide (0 index)
'directionNav'=> true, // Next & Prev navigation
'controlNav'=> true, // 1,2,3... navigation
'controlNavThumbs'=> false, // Use thumbnails for Control Nav
'pauseOnHover'=> false, // Stop animation while hovering
'manualAdvance'=> false, // Force manual transitions
'prevText'=> 'Prev', // Prev directionNav text
'nextText'=> 'Next', // Next directionNav text
'randomStart'=> false);
extract($default);
$slider_script;
?>
<script type='text/javascript'>
$(window).load(function() {
$('#slider_slide').nivoSlider({
effect:<?php echo "$effect"; ?>,

});});
</script>
<?php
}
add_action('wp_footer','slider_option');
?>
