So I stumbled upon this question and I wanted to figure out how to find the mean, median, mode, highest number, lowest number, how many evens, and how many odds are in each row... I honestly can't figure this out...
I want it to display next to the table I have created, which is the last table... and I want to connect the new colums to the original table... do you see what I mean?

Here is my code:

<p>
  <?php
$x=0;
$min=900;
$max=2000;
// initialize array of random values
$random_array = array();
// initialize temporary array for sorting
$temp_array = array();
// start html table for random values
echo "<table border=\"1\">";
// create $random_array with random numbers, display html table rows and
// store each value in onedimensional $temp_array for sorting
for($row=1;$row<=10; $row++){
    echo "<tr>\n";
    for($col=1;$col<=10; $col++) {
        $x=rand($min,$max);
        $random_array[$row][$col] = $x;
        echo"<td>$x</td>\n"; 
        // add value to the $temp_array
        $temp_array[] = $x;
    }
    echo "</tr>";
}
// end the html table
echo "</table>";
?>
</p>
<p>
  <?php
// sort the $temp_array (sort works on onedimensional arrays)
sort($temp_array);
// start a table for sorted values
echo "<table border=\"1\">";
// initialize counter that will be the $temp_array's key
$key = 0;
// display html table rows of sorted values
for($row=1;$row<=10; $row++){
    echo "<tr>\n";
    for($col=1;$col<=10; $col++) {
        echo"<td>{$temp_array[$key]}</td>\n";
        // increase the key
        $key++; 
    }
    echo "</tr>";
}
// end the html table of sorted values
echo "</table>";
?>
</p>
<p>
  <?php
// sort the $temp_array (sort works on onedimensional arrays)
rsort($temp_array);
// start a table for sorted values
echo "<table border=\"1\">";
// initialize counter that will be the $temp_array's key
$key = 0;
// display html table rows of sorted values
for($row=1;$row<=10; $row++){
    echo "<tr>\n";
    for($col=1;$col<=10; $col++) {
        echo"<td>{$temp_array[$key]}</td>\n";
        // increase the key
        $key++; 
    }
    echo "</tr>";
}
// end the html table of sorted values
echo "</table>";
?>
</p>
<?php
echo "<table border=\"1\">";
$AVE=0;
$mean=0;
for($row=1;$row<=10; $row++){
    echo "<tr>\n";
    for($col=1;$col<=10; $col++) {
        $AVE=$AVE+$random_array[$row][$col];
        $mean=$mean($random_array) . '<br>';
        if($random_array[$row][$col] % 2 == 0) {
            $char = '*';
        } else {
            $char = '%';
        }
        $C=$random_array[$row][$col];
        echo"<td>$char $C</td>\n";
        // add value to the $temp_array
        $temp_array[] = $x;
    }
    echo "</tr>";
}
echo "</table>";
        $CAL_AVE=$AVE/400;
        echo "$CAL_AVE";
        echo 'Mean: '.mmmr($random_array, 'mean') . '<br>';
?>

Tell me if you need more of an explanation of what I am attempting :)
Thanks!

You already outputted the table, so connecting them is not possible. What you should do is calculate before outputting those tables, and then create the new one in a single loop.

Ok, lemme try that!

Well, i'm not that successful... do you mind giving me an example? I am a newbie coder, so my skills are weak compared to yours.

You now use separate loops for your tables, you need to merge them into one. So instead of having:

for($row = 1; $row <= 10; $row++) {
  echo "<tr>\n";
  for($col = 1; $col <= 10; $col++) {

three times, you only need that once. The different bodies use different arrays, so make sure they are all generated before the new loop.
