Sampling Error The margin <strong>of</strong> <strong>the</strong> sampling error for <strong>the</strong> total survey <strong>of</strong> 820 <strong>Jewish</strong> households is +/- 3.2 percentage points. Within <strong>the</strong> RDD portion <strong>of</strong> <strong>the</strong> sample, <strong>the</strong> margin <strong>of</strong> error is +/- 8.2 percentage points. The margins <strong>of</strong> error for <strong>the</strong> population estimates by region are as follows: Figure 100: Margin <strong>of</strong> Error by Region Total Jews Standard Error Margin <strong>of</strong> Error 95% Confidence Interval Lower Upper Oakland-Berkeley Corridor 64,220 5,353 10,492 53,728 74,712 Hayward Area 9,955 3,164 6,201 3,754 16,156 Tri-valley Tri-cities 23,720 3,888 7,620 16,100 31,341 LAMORINDA 5,013 1,827 3,581 1,433 8,594 Central Contra Costa 22,207 3,427 6,717 15,490 28,924 680 Corridor 6,379 2,458 4,818 1,561 11,196 Western Contra Costa 11,376 1,803 3,533 7,843 14,910 <strong>East</strong>ern Contra Costa 10,672 2,752 5,394 5,278 16,066 Solano County 12,076 2,837 5,560 6,516 17,636 Napa County 11,197 4,573 8,963 2,235 20,160 Total 176,816 10,425 20,433 156,383 197,249 Please note that <strong>the</strong> margin <strong>of</strong> error estimates do not account for sources <strong>of</strong> error o<strong>the</strong>r than sampling error, such as self-selection bias, attrition bias, or exclusion bias. The overall margin <strong>of</strong> error estimates are <strong>the</strong> most conservative estimates <strong>of</strong> <strong>the</strong> margin <strong>of</strong> error and apply when percentages are close to 50 percent. As percentages move closer to 0 or 100, <strong>the</strong> margin <strong>of</strong> error shrinks. Please see <strong>the</strong> table below for guidance. Also remember that subpopulations will have a larger margin <strong>of</strong> error. 109
