Mode Component (class) in Coldfusion

In statistics, the mode is the value that occurs the most frequently in a data set or a probability distribution. In some fields, notably education, sample data are often called scores, and the sample mode is known as the modal score. [1]

The code below will find the mode value in a non sorted array.

Save the below component with the name mode.cfc in a directory under wwwroot, in my case I save my components in a directory called classes:
<cfcomponent>
    <cffunction name="getMode" access="public" returntype="string">
      <cfargument name="amode" type="array" required="true">
      <cfset oldcount=0><cfset oldtemp=0>
      <cfloop from="1" to="#arrayLen(amode)-1#" index="i">
        <cfset temp=amode[i]>
        <cfset count=1>
        <cfloop from="#i+1#" to="#arrayLen(amode)-1#" index="j">
          <cfif temp is amode[j]>
            <cfset count=count+1>
          </cfif>
          <cfif count GT oldcount>
            <cfset oldtemp=temp>
            <cfset oldcount=count>

          </cfif>

        </cfloop>

      </cfloop>
      <cfreturn oldtemp>

    </cffunction>

</cfcomponent>



To call this component in your code you have to do the following:

1-Invoke the object:

    <cfobject
    name="mode"
    component="classes.mode">

2- Call the getMode method and forward the array of the values:

    <cfoutput> #mode.getMode(amode1)# </cfoutput>



Hope this will help.
