Hi Waterside; 
 
See if this meets your needs.
<pre><code class="code-10 nolinks" id="code-20-41368261-1">// Used to create test data
Random rnd = new Random(DateTime.Now.Second);
// The data itself
List&lt;int&gt; data = new List&lt;int&gt;();
// Fill the list of test data
for (int i = 0; i &lt;= 100; i++)
{
 data.Add(rnd.Next(0, 101));
}

// The query to get the Frequency in each range.
// GroupingNo 0 = 0 - 9, 1 = 10 - 19 and so on.
var groupings = (from num in data
 group num by num / 10 into rGroup
 orderby rGroup.Key
 select new
 {
 GroupingNo = rGroup.Key,
 Frequency = rGroup.Count()
 }
 ).ToList();

Hi. &nbsp;Sorry for leaving this so long (Holidays :) 
 
@Fernando I'm getting and error at 'num by num/10' 
 
I'm using vb.net so I tried... 
 
Dim groupings = (From num In data 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Group num By numgroup = CInt(num / 10) Into Group 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Order By numgroup 
&nbsp; &nbsp; &nbsp; &nbsp; Select New With {.Range = numgroup, .Total = Group.Count}).ToList 
 
but I get .. 
 
In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.
</div>

<div>
I shall share my solution in VB.Net soon.
</div>

<div>
Thank you both. 
 
Fernando's solution was more what I had in mind, but Karrtik's approach would allow me to specify custom groupings such as 10-20, 20-60, 60-70, which will come in handy :)

How would I split a query's data into groups to analyse distribution ? 
 
If my data was say integers from 1 to 100, I'd like to get 
 
1-10 count = 6 
11-20 count =3 
21-30 count = 5 
31-40 count = 2 etc 
 
It would be really cool if there was a method to specify the number of groupings for the range of data values. 
 
pseudo for above.. &nbsp;Group at d.Max / 10 (ten groupings) 
 
Any thoughts ?
