The survey was conducted by telephone by student volunteers at the College of Southern Maryland on Nov. 7-8 and 13-15. The numbers were selected randomly from the telephone book.
The 594 respondents were roughly proportionally representative of the three counties, with 27 percent of respondents from Calvert County, 40 percent of respondents from Charles County and 29 percent from St. Mary’s County; the three counties’ populations respectively comprise 26 percent, 43 percent and 31 percent of the region’s total.
The overall margin of error was 4 percentage points.
Sampling error increases when broken down by sex, age and other characteristics, meaning the results are less reliable. The survey summary warned that “caution should be used when making inferences about the segmented data” on these bases.
