 Try to anticipate where these types of problems (procedural errors) might occur as you collect data for your 'Idea" in the following activity.  It is likely that you will need to refine your data collection procedure in a similar way that you have just refined your resources in the previous part of this activity.
+As an aside:  Once your students are used to working in the spirit of enquiry you can pose short enquiry problems to be solved for homework or at various stages of a lesson.  For example, the teacher in the above clip might have asked the students to work out a solution to the problem of the measuring tape not starting at the floor with the proviso that the solution should not include measuring Martha again or moving the measuring tape.  The answer of course is to measure the gap between the tape and the floor and add this to Martha's incorrect height measurement.  By giving the students a few minutes to discuss the problem in groups of thee or four, they may have come up with this (or perhaps another even better) solution - students can sometimes surprise us with their ingenuity.  Once the size of the gap has been worked out, this result can be added to all other measurements carried out using that tape - the students will see this as a worthwhile exercise because it means that they don't have to measure everyone who used that tape again!
