				Sampling
				Plan/Procedures:  
				 
				A
				systematic sample of all visitors (at all locations listed in
				table 1 above) will be contacted by trained within the parks
				during the survey period.
				The
				survey design and sampling plan for this collection visitor
				studies is based upon a similar method applied system-wide for
				Social Economic Monitoring (SEM) survey and previous versions of
				the Visitor Service Project surveys. 
				 
 The
				sampling will be based on the 2015 visitation statistics. We will
				intercept visitors at a 5 to 10 minute intervals.  When each
				visitor group is stopped and asked to participate we will
				determine acceptance or refusal.  If they accept the person with
				the nearest birthday from the group will be selected, a
				questionnaire and reply business mail envelop for returning the
				questionnaire will be distributed to that person.  Contact
				information for follow up purpose and information used for
				non-response bias checking will be recorded using a script as
				described in the Instrument Administration section below.
				If
				the visitor refuses, information used for non-response bias
				testing will be recorded as described in the section below. 
				 
 Each
				interviewer will be instructed to contact visitors at a
				5-10minute interval at each of the park locations. For every two
				hours of survey distribution a half hour counting period will be
				performed. During the counting period, visitors will not be
				contacted. The count data will be used for weighting the survey
				results if needed. The actual interval used will be recorded on
				the survey log by interviewers. The Interviewer will be trained
				on every aspect of on-site surveying including: using sampling
				intervals, avoiding sampling bias, and how to handle all types of
				interviewing situations, especially safety of the visitors and
				the interviewers. Quality control will be ensured by monitoring
				interviewers in the field, and by checking their paperwork at the
				end of each survey day. 
 
					
					Instrument
					Administration: 
					 
				The
				initial contact with visitors will be used to explain the study
				and determine if visitors are interested in participating. This
				should take approximately 1 minute. All individuals asked to
				participate in the study will be asked the non-response bias
				questions to collect information that will be used in the final
				analysis (see item 9e below). Visitors that refuse to participate
				will be asked if they would be willing to take two minutes to
				respond to the non-response bias questions. The number of
				refusals will be recorded and used to calculate the overall
				response rate for the collection. 
				 Visitors
				selected for participation in the survey will be read the
				following script: 
				
 
				“Hello,
				my name is _________.  I am conducting a survey for the National
				Park Service to better understand your
				opinions about this park's programs and services.
				Your participation is voluntary and all responses will be kept
				anonymous. Would you be willing to take a questionnaire and mail
				it back to us using the self-addressed envelope?” 
				
 
					
						
						
							
							
								| 
									If
									YES
									– then ask, “has any member of your group been
									asked to participate in this survey before?” |  
								| 
									If
									“YES”
									(already asked to participate) then, “Thank
									you for agreeing to participate in this study we hope that
									you will return the questionnaire soon.  Have a great day.” |  
								| 
									If
									“NO”
									(have not been previously asked to participate) then, 
									 “Thank
									you for agreeing to participate. Who in your group is at
									least 18 years old and has the next birthday?
									[The surveyor will ask them to start the process by
									answering the non-response bias questions (listed below).
									The responses will be recorded in spaces provided on the
									tracking sheet. The surveyor will hand them a survey packet
									including the questionnaire and a self-addressed stamp
									envelope]. |  
								| 
									If
									NO– (soft refusal) - ask them if they would be willing
									to answer the non-response bias questions (listed below) and
									then thank them for their time.
									[The
									surveyor will record responses in spaces provided on the
									tracking sheet]. |  
								| 
									If
									NO– (hard refusal) - end the contact and thank them
									for their time. |  
				
 
				Once
				the visitor has agreed to participate in the study, we will ask
				them to provide or personally record their name, address, and
				phone number or email address on the survey tracking sheet –
				this information will only be used to follow-up with all
				non-respondents.  At the end of the on-site sampling period, all
				visitors accepting a survey packet on-site will be mailed a thank
				you/reminder postcard within 11 working days. A reminder letter
				with a stamped, addressed replacement questionnaire will be sent
				to non-respondents 21 working days after the end of the survey
				period. Once the data collection is complete, all hard copies of
				contact information will be destroyed by shredding and deleting
				any electronic files.

					Expected
					Response Rate/Confidence Levels: 
				The
				same methodology for this collection has been applied in similar
				studies at other NPS site with similar resources or in the same
				geographical area and based on the data of the survey at ARCH in
				2003 and at GLCA in 2007. 
				
 
					
					Arches
					National Park at 73% (n=652) response rate (August 10-18, 2003)Glen
					Canyon National Recreation Area (summer) 59% (n=1,175) response
					rate (July 14-20, 2007)
					Glen
					Canyon National Recreation Area (spring) at 64% (n=968) response
					rate (May 2-8, 2007) 
				
 
				A
				total of 2,092 visitors will be contacted during the sampling
				periods (ARCH n=924 and GLCA n=1,168). We estimate that 1,925
				(92%) visitors will agree on-site to participate in the survey.
				The number of refusals will be recorded and reported in a survey
				log, and will be used in calculating the response rate. Among
				which 404 visitors at ARCH (44%) and 591 visitors at GLCA (55%)
				are expected to complete and return the survey by mail. This
				response rate was estimated based on surveys result of similar
				NPS units in the area as cited in section b. Based on the survey
				sample size, there will be 95% confidence that the day-use survey
				findings will be accurate to within 4 to 6 percentage points.
