Using Response Rate variables in filters

Example – low responders

Using Panel Manager you may want to filter on panel members with a low response rate over the last twelve months.  To do this you could create a named filter using the variable Response Rate (Last 12 Months).

In this example the filter will return all panellists where the response rate is between 1% and 25% over the last twelve months.

When the filter has been executed the columns Response Rate (Last 12 Months) and the Total Invites (Last 12 Months) could also be displayed.

You can now examine the low-responding panellists and decide how to deal with them.

You may want to add more conditions to your filter, or display more columns in Panel Manager to help with identification.

Example - speeders

A positive average or median diff interview length indicates that the panellist usually takes longer than expected to complete an interview.  A negative average or median diff interview length indicates that the panellist usually takes less time than expected to complete an interview – so may be a speeder.

Using Panel Manager you may want to identify possible speeders by looking at the median interview length over the last twelve months.  To do this you could create a named filter using the variable Median Diff IntLength (Last 12 Months).

In this example the filter will return all panellists where the median diff interview length is less than or equal to zero.

Note that to enter a negative range, the negative values must be entered enclosed in single quotes.  For example, to filter on the range -300 to -100 enter the numeric range ‘-300’-‘-100’.

When the filter has been executed, you could also display the column Median Diff IntLength v Expected (Last 12 Months).

You can now examine the possible speeders and decide how to deal with them.

You may want to add more conditions to your filter, or display more columns in Panel Manager to help with identification.
