MIYHS CORE QUESTIONS: 2015 VERSUS 2017 COMPARISON REPORT	
	
CENTRAL MAINE PHD	
	
2017 MIYHS GRADE 5-6 REPORT	

UNDERSTANDING THE DATA	
	
Reporting Thresholds and Student Confidentiality	
	
Core reports have been run on the following levels for individual geographic units receiving weighted data, as survey design, response rates, and confidentiality protections allow:	
·         Grade 5-6:  State, Public Health District (PHD), SAU, and School	
·         Middle School:  State, PHD, County, SAU, and School	
·         High School:  State, PHD, County, SAU, and School	

To protect student confidentiality, responses based on fewer than 6 individuals will not be shown.  Also, individual reports have not been generated for schools or school districts yielding fewer than 20 usable surveys.	
	
How to Read this Report	
	
For the Grade 5-6 core reports, all non-demographic questions included on the 2017 MIYHS survey instrument are presented.  For middle school (MS) and high school (HS), only questions that appeared on all four survey versions are included in the core reports.  Questions are grouped by topic area.	
	
Please note that the numbers listed to the left of the questions in this report are for formatting purposes only; they do not represent actual question numbers on the survey instruments themselves.	
	
When questions and/or answer options have changed from 2015 to 2017 and there may be a change in the way the results could be interpreted, the word "Modified" is listed after the question.  Please go to  for more information on the modified variables.	
	
Each estimate is the weighted percentage of students who answered in the way specified in the question title; for instance, in 2017, 22.5% of Maine's high school students said they had consumed alcohol at least once in the 30 days prior to taking the MIYHS. The percentages are weighted to adjust for non-response and to make the estimates more representative of all Maine students, not just those who took the survey.	
	
Because the weighted percentage is an estimate, there is some error involved.  This is reflected in the Confidence Interval, which is bounded by the Lower Confidence Limit (LCL) and the Upper Confidence Limit (UCL).  Confidence intervals quantify the degree of uncertainty in rate or prevalence estimates that result from sampling or random variability. Like the margin of error presented in political polls, the confidence interval presents a range of values within which the true underlying rate or prevalence is likely to lie. The 95% confidence interval is most commonly used, and is presented in this report.

UNDERSTANDING THE DATA	
	
Comparing Data:  Is a Difference Statistically Significant?	
	
In the last three columns of the tables in the core report, we present the results of statistical tests designed to determine whether the difference between values is more than would have been expected by chance.  Statistical significance was determined by comparing confidence intervals. If the confidence interval around one percentage does not overlap with the confidence interval around another percentage, then the estimates are considered significantly different.  Each geographic unit is compared to the state in 2015 and in 2017, and the values for these two survey years are compared within the geographic unit as well.  If there is an "H" in a significance tests column, the percentage on this indicator is statistically higher than the state average or the previous survey year; if there is an "L", this indicates that the percentage on this indicator is statistically lower than the state average or the previous survey year.   If the cell is blank, then the comparison is not statistically significantly different. To protect the privacy of students in small schools where data has not been released, statistically significant differences between the state and the school are not shown for indicators that are very rare or very common in Maine (i.e., almost no students or almost all students reported it).  Otherwise, the reports will still display statistically significant differences, even if privacy concerns prevent us from showing local data.
